Fixes#8920
Limits the amount of non-racked devices on Site and Location view to 10 and provides a link to the device list this is pre-filtered to the relevant site or location.
When using permissions that use tags, a user may receive multiple permissions
of the same type if multiple tags are assigned to the device. This causes the
RestrictedQuerySet class to generate a query similar to this:
>>> dcim.models.Device.objects.filter(Q(tags__name='tag1')|Q(tags__name='tag2'))
<ConfigContextModelQuerySet [<Device: device1>, <Device: device1>]>
This query returns the same object twice if both tags are assigned to it. This
is due to the use of the django-taggit library. The library's documentation
describes this behavior as expected and suggests using an explicit distinct()
call in queries to avoid duplicates.
However, the use of DISTINCT in queries has a global side effect -
deduplication of responses, which may or may not be acceptable behavior
(depending on further use). Since it is not known how RestrictedQuerySet will
be used in the rest of the code, it was decided to dedupe using a subquery.

When users are authenticated with an API token not all permissions where
assigned to the session because the LDAP group memberships where not
available.
Now the information is loaded from the directory if the user is found.
If not the local group memberships are used.
This prevents a crash when the current user has authenticated himself
with an API token. In this case the user will not have the permissions
given to his LDAP groups.
When AUTH_LDAP_FIND_GROUP_PERMS is set to true the filter to find the
users permissions is extended to search for all permissions assigned to
groups in which the LDAP user is.

With this commit all dates in the UI are now consistently displayed.
I changed the long date format as suggested by @xkilian and confirmed by my own
research.
* DATETIME_FORMAT
* Before July 20, 2020 4:52 p.m.
* Now 20th July, 2020 16:52
"20th July, 2020" would be spoken as "the 20th of July, 2020" but the "the" and
"of" are never written.
The only exception is `object_list.html`. I tried it but there it does not
work so easily because the dates are passed to Jinja as SafeString.

New validate_form method on ComponentCreateView handles validation generically, which any post() method on ComponentCreateView can use to validate the form but handle the response differently as needed.
There are situations in which it is convenient to be able to modify the name of the cookie that the application uses for storing the session token (conflicts with other cookies on the same domain, for example).
At present, a mix of link types are used in the Netbox
documentation from markdown file links to relative and
absolute anchor links.
Of the three types, linking to markdown files is the
most ideal because it allows navigation locally on disk,
as well as being translated into working links at render
time.
While not obvious, mkdocs handles converting markdown
links to valid URLs.

NetBox is an infrastructure resource modeling (IRM) tool designed to empower
network automation, used by thousands of organizations around the world.
Initially conceived by the network engineering team at
[DigitalOcean](https://www.digitalocean.com/), NetBox was developed specifically
to address the needs of network and infrastructure engineers. It is intended to
function as a domain-specific source of truth for network operations.
Myriad infrastructure components can be modeled in NetBox, including:
* Hierarchical regions, site groups, sites, and locations
* Racks, devices, and device components
* Cables and wireless connections
* Power distribution
* Data circuits and providers
* Virtual machines and clusters
* IP prefixes, ranges, and addresses
* VRFs and route targets
* FHRP groups (VRRP, HSRP, etc.)
* AS numbers
* VLANs and scoped VLAN groups
* Organizational tenants and contacts
In addition to its extensive built-in models and functionality, NetBox can be
customized and extended through the use of:
* Custom fields
* Custom links
* Configuration contexts
* Custom model validation rules
* Reports
* Custom scripts
* Export templates
* Conditional webhooks
* Plugins
* Single sign-on (SSO) authentication
* NAPALM integration
* Detailed change logging
NetBox also features a complete REST API as well as a GraphQL API for easily
integrating with other tools and systems.
NetBox runs as a web application atop the [Django](https://www.djangoproject.com/)
Python framework with a [PostgreSQL](http://www.postgresql.org/) database. For a

Per the terms of the Apache 2 license, NetBox is offered "as is" and without any guarantee or warranty pertaining to its operation. While every reasonable effort is made by its maintainers to ensure the product remains free of security vulnerabilities, users are ultimately responsible for conducting their own evaluations of each software release.
## Recommendations
Administrators are encouraged to adhere to industry best practices concerning the secure operation of software, such as:
* Do not expose your NetBox installation to the public Internet
* Do not permit multiple users to share an account
* Enforce minimum password complexity requirements for local accounts
* Prohibit access to your database from clients other than the NetBox application
* Keep your deployment updated to the most recent stable release
## Reporting a Suspected Vulnerability
If you believe you've uncovered a security vulnerability and wish to report it confidentially, you may do so via email. Please note that any reported vulnerabilities **MUST** meet all the following conditions:
* Affects the most recent stable release of NetBox, or a current beta release
* Affects a NetBox instance installed and configured per the official documentation
* Is reproducible following a prescribed set of instructions
Please note that we **DO NOT** accept reports generated by automated tooling which merely suggest that a file or file(s) _may_ be vulnerable under certain conditions, as these are most often innocuous.
If you believe that you've found a vulnerability which meets all of these conditions, please email a brief description of the suspected bug and instructions for reproduction to **security@netbox.dev**. For any security concerns regarding NetBox deployed via Docker, please see the [netbox-docker](https://github.com/netbox-community/netbox-docker) project.
### Bug Bounties
As NetBox is provided as free open source software, we do not offer any monetary compensation for vulnerability or bug reports, however your contributions are greatly appreciated.
NetBox supports database query caching using [django-cacheops](https://github.com/Suor/django-cacheops) and Redis. When a query is made, the results are cached in Redis for a short period of time, as defined by the [CACHE_TIMEOUT](../../configuration/optional-settings/#cache_timeout) parameter (15 minutes by default). Within that time, all recurrences of that specific query will return the pre-fetched results from the cache.
If a change is made to any of the objects returned by the query within that time, or if the timeout expires, the results are automatically invalidated and the next request for those results will be sent to the database.
## Invalidating Cached Data
Although caching is performed automatically and rarely requires administrative intervention, NetBox provides the `invalidate` management command to force invalidation of cached results. This command can reference a specific object my its type and numeric ID:
Every time an object in NetBox is created, updated, or deleted, a serialized copy of that object is saved to the database, along with meta data including the current time and the user associated with the change. These records form a persistent record of changes both for each individual object as well as NetBox as a whole. The global change log can be viewed by navigating to Other > Change Log.
Every time an object in NetBox is created, updated, or deleted, a serialized copy of that object taken both before and after the change is saved to the database, along with meta data including the current time and the user associated with the change. These records form a persistent record of changes both for each individual object as well as NetBox as a whole. The global change log can be viewed by navigating to Other > Change Log.
A serialized representation of the instance being modified is included in JSON format. This is similar to how objects are conveyed within the REST API, but does not include any nested representations. For instance, the `tenant` field of a site will record only the tenant's ID, not a representation of the tenant.
Each object in NetBox is represented in the database as a discrete table, and each attribute of an object exists as a column within its table. For example, sites are stored in the `dcim_site` table, which has columns named `name`, `facility`, `physical_address`, and so on. As new attributes are added to objects throughout the development of NetBox, tables are expanded to include new rows.
However, some users might want to associate with objects attributes that are somewhat esoteric in nature, and that would not make sense to include in the core NetBox database schema. For instance, suppose your organization needs to associate each device with a ticket number pointing to the support ticket that was opened to have it installed. This is certainly a legitimate use for NetBox, but it's perhaps not a common enough need to warrant expanding the internal data schema. Instead, you can create a custom field to hold this data.
Custom fields must be created through the admin UI under Extras > Custom Fields. To create a new custom field, select the object(s) to which you want it to apply, and the type of field it will be. NetBox supports six field types:
* Free-form text (up to 255 characters)
* Integer
* Boolean (true/false)
* Date
* URL
* Selection
Assign the field a name. This should be a simple database-friendly string, e.g. `tps_report`. You may optionally assign the field a human-friendly label (e.g. "TPS report") as well; the label will be displayed on forms. If a description is provided, it will appear beneath the field in a form.
Marking the field as required will require the user to provide a value for the field when creating a new object or when saving an existing object. A default value for the field may also be provided. Use "true" or "false" for boolean fields. (The default value has no effect for selection fields.)
When creating a selection field, you should create at least two choices. These choices will be arranged first by weight, with lower weights appearing higher in the list, and then alphabetically.
## Using Custom Fields
When a single object is edited, the form will include any custom fields which have been defined for the object type. These fields are included in the "Custom Fields" panel. On the backend, each custom field value is saved separately from the core object as an independent database call, so it's best to avoid adding too many custom fields per object.
When editing multiple objects, custom field values are saved in bulk. There is no significant difference in overhead when saving a custom field value for 100 objects versus one object. However, the bulk operation must be performed separately for each custom field.
Custom links allow users to display arbitrary hyperlinks to external content within NetBox object views. These are helpful for cross-referencing related records in systems outside of NetBox. For example, you might create a custom link on the device view which links to the current device in a network monitoring system.
Custom links are created under the admin UI. Each link is associated with a particular NetBox object type (site, device, prefix, etc.) and will be displayed on relevant views. Each link is assigned text and a URL, both of which support Jinja2 templating. The text and URL are rendered with the context variable `obj` representing the current object.
Custom links appear as buttons at the top right corner of the page. Numeric weighting can be used to influence the ordering of links.
## Conditional Rendering
Only links which render with non-empty text are included on the page. You can employ conditional Jinja2 logic to control the conditions under which a link gets rendered.
For example, if you only want to display a link for active devices, you could set the link text to
```jinja2
{% if obj.status == 'active' %}View NMS{% endif %}
```
The link will not appear when viewing a device with any status other than "active."
As another example, if you wanted to show only devices belonging to a certain manufacturer, you could do something like this:
```jinja2
{% if obj.device_type.manufacturer.name == 'Cisco' %}View NMS{% endif %}
```
The link will only appear when viewing a device with a manufacturer name of "Cisco."
## Link Groups
Group names can be specified to organize links into groups. Links with the same group name will render as a dropdown menu beneath a single button bearing the name of the group.
NetBox allows users to define custom templates that can be used when exporting objects. To create an export template, navigate to Extras > Export Templates under the admin interface.
Each export template is associated with a certain type of object. For instance, if you create an export template for VLANs, your custom template will appear under the "Export" button on the VLANs list.
Export templates may be written in Jinja2 or [Django's template language](https://docs.djangoproject.com/en/stable/ref/templates/language/), which is very similar to Jinja2.
!!! warning
Support for Django's native templating logic will be removed in NetBox v2.10.
The list of objects returned from the database when rendering an export template is stored in the `queryset` variable, which you'll typically want to iterate through using a `for` loop. Object properties can be access by name. For example:
```jinja2
{% for rack in queryset %}
Rack: {{ rack.name }}
Site: {{ rack.site.name }}
Height: {{ rack.u_height }}U
{% endfor %}
```
To access custom fields of an object within a template, use the `cf` attribute. For example, `{{ obj.cf.color }}` will return the value (if any) for a custom field named `color` on `obj`.
A MIME type and file extension can optionally be defined for each export template. The default MIME type is `text/plain`.
## Example
Here's an example device export template that will generate a simple Nagios configuration from a list of devices.
```
{% for device in queryset %}{% if device.status and device.primary_ip %}define host{
use generic-switch
host_name {{ device.name }}
address {{ device.primary_ip.address.ip }}
}
{% endif %}{% endfor %}
```
The generated output will look something like this:
Native support for embedded graphs is due to be removed in NetBox v2.10. It will likely be superseded by a plugin providing similar functionality.
NetBox does not have the ability to generate graphs natively, but this feature allows you to embed contextual graphs from an external resources (such as a monitoring system) inside the site, provider, and interface views. Each embedded graph must be defined with the following parameters:
* **Type:** Site, device, provider, or interface. This determines in which view the graph will be displayed.
* **Weight:** Determines the order in which graphs are displayed (lower weights are displayed first). Graphs with equal weights will be ordered alphabetically by name.
* **Name:** The title to display above the graph.
* **Source URL:** The source of the image to be embedded. The associated object will be available as a template variable named `obj`.
* **Link URL (optional):** A URL to which the graph will be linked. The associated object will be available as a template variable named `obj`.
Graph names and links can be rendered using Jinja2 or [Django's template language](https://docs.djangoproject.com/en/stable/ref/templates/language/).
## Examples
You only need to define one graph object for each graph you want to include when viewing an object. For example, if you want to include a graph of traffic through an interface over the past five minutes, your graph source might looks like this:
All primary objects in NetBox support journaling. A journal is a collection of human-generated notes and comments about an object maintained for historical context. It supplements NetBox's change log to provide additional information about why changes have been made or to convey events which occur outside NetBox. Unlike the change log, in which records typically expire after a configurable period of time, journal entries persist for the life of their associated object.
Each journal entry has a selectable kind (info, success, warning, or danger) and a user-populated `comments` field. Each entry automatically records the date, time, and associated user upon being created.
NetBox supports integration with the [NAPALM automation](https://napalm-automation.net/) library. NAPALM allows NetBox to serve a proxy for operational data, fetching live data from network devices and returning it to a requester via its REST API. Note that NetBox does not store any NAPALM data locally.

When deploying NetBox in a multiprocess manner (e.g. running multiple Gunicorn workers) the Prometheus client library requires the use of a shared directory to collect metrics from all worker processes. To configure this, first create or designate a local directory to which the worker processes have read and write access, and then configure your WSGI service (e.g. Gunicorn) to define this path as the `prometheus_multiproc_dir` environment variable.
!!! warning
If having accurate long-term metrics in a multiprocess environment is crucial to your deployment, it's recommended you use the `uwsgi` library instead of `gunicorn`. The issue lies in the way `gunicorn` tracks worker processes (vs `uwsgi`) which helps manage the metrics files created by the above configurations. If you're using Netbox with gunicorn in a containerized enviroment following the one-process-per-container methodology, then you will likely not need to change to `uwsgi`. More details can be found in [issue #3779](https://github.com/netbox-community/netbox/issues/3779#issuecomment-590547562).

A webhook is a mechanism for conveying to some external system a change that took place in NetBox. For example, you may want to notify a monitoring system whenever the status of a device is updated in NetBox. This can be done by creating a webhook for the device model in NetBox and identifying the webhook receiver. When NetBox detects a change to a device, an HTTP request containing the details of the change and who made it be sent to the specified receiver. Webhooks are configured in the admin UI under Extras > Webhooks.
## Conditional Webhooks
## Configuration
A webhook may include a set of conditional logic expressed in JSON used to control whether a webhook triggers for a specific object. For example, you may wish to trigger a webhook for devices only when the `status` field of an object is "active":
* **Name** - A unique name for the webhook. The name is not included with outbound messages.
* **Object type(s)** - The type or types of NetBox object that will trigger the webhook.
* **Enabled** - If unchecked, the webhook will be inactive.
* **Events** - A webhook may trigger on any combination of create, update, and delete events. At least one event type must be selected.
* **HTTP method** - The type of HTTP request to send. Options include `GET`, `POST`, `PUT`, `PATCH`, and `DELETE`.
* **URL** - The fuly-qualified URL of the request to be sent. This may specify a destination port number if needed.
* **HTTP content type** - The value of the request's `Content-Type` header. (Defaults to `application/json`)
* **Additional headers** - Any additional headers to include with the request (optional). Add one header per line in the format `Name: Value`. Jinja2 templating is supported for this field (see below).
* **Body template** - The content of the request being sent (optional). Jinja2 templating is supported for this field (see below). If blank, NetBox will populate the request body with a raw dump of the webhook context. (If the HTTP cotent type is set to `application/json`, this will be formatted as a JSON object.)
* **Secret** - A secret string used to prove authenticity of the request (optional). This will append a `X-Hook-Signature` header to the request, consisting of a HMAC (SHA-512) hex digest of the request body using the secret as the key.
* **SSL verification** - Uncheck this option to disable validation of the receiver's SSL certificate. (Disable with caution!)
* **CA file path** - The file path to a particular certificate authority (CA) file to use when validating the receiver's SSL certificate (optional).
## Jinja2 Template Support
[Jinja2 templating](https://jinja.palletsprojects.com/) is supported for the `additional_headers` and `body_template` fields. This enables the user to convey object data in the request headers as well as to craft a customized request body. Request content can be crafted to enable the direct interaction with external systems by ensuring the outgoing message is in a format the receiver expects and understands.
For example, you might create a NetBox webhook to [trigger a Slack message](https://api.slack.com/messaging/webhooks) any time an IP address is created. You can accomplish this using the following configuration:
* Object type: IPAM > IP address
* HTTP method: `POST`
* URL: Slack incoming webhook URL
* HTTP content type: `application/json`
* Body template: `{"text": "IP address {{ data['address'] }} was created by {{ username }}!"}`
### Available Context
The following data is available as context for Jinja2 templates:
*`event` - The type of event which triggered the webhook: created, updated, or deleted.
*`model` - The NetBox model which triggered the change.
*`timestamp` - The time at which the event occurred (in [ISO 8601](https://en.wikipedia.org/wiki/ISO_8601) format).
*`username` - The name of the user account associated with the change.
*`request_id` - The unique request ID. This may be used to correlate multiple changes associated with a single request.
*`data` - A serialized representation of the object _after_ the change was made. This is typically equivalent to the model's representation in NetBox's REST API.
### Default Request Body
If no body template is specified, the request body will be populated with a JSON object containing the context data. For example, a newly created site might appear as follows:
For more detail, see the reference documentation for NetBox's [conditional logic](../reference/conditions.md).
## Webhook Processing
When a change is detected, any resulting webhooks are placed into a Redis queue for processing. This allows the user's request to complete without needing to wait for the outgoing webhook(s) to be processed. The webhooks are then extracted from the queue by the `rqworker` process and HTTP requests are sent to their respective destinations. The current webhook queue and any failed webhooks can be inspected in the admin UI under Django RQ > Queues.

This allows the user's request to complete without needing to wait for the outgoing webhook(s) to be processed. The webhooks are then extracted from the queue by the `rqworker` process and HTTP requests are sent to their respective destinations. The current webhook queue and any failed webhooks can be inspected in the admin UI under System > Background Tasks.
A request is considered successful if the response has a 2XX status code; otherwise, the request is marked as having failed. Failed requests may be retried manually via the admin UI.
This guide explains how to configure single sign-on (SSO) support for NetBox using [Microsoft Azure Active Directory (AD)](https://azure.microsoft.com/en-us/services/active-directory/) as an authentication backend.
## Azure AD Configuration
### 1. Create a test user (optional)
Create a new user in AD to be used for testing. You can skip this step if you already have a suitable account created.
### 2. Create an app registration
Under the Azure Active Directory dashboard, navigate to **Add > App registration**.
Enter a name for the registration (e.g. "NetBox") and ensure that the "single tenant" option is selected.
Under "Redirect URI", select "Web" for the platform and enter the path to your NetBox installation, ending with `/oauth/complete/azuread-oauth2/`. Note that this URI **must** begin with `https://` unless you are referencing localhost (for development purposes).
NetBox also supports multitenant authentication via Azure AD, however it requires a different backend and an additional configuration parameter. Please see the [`python-social-auth` documentation](https://python-social-auth.readthedocs.io/en/latest/backends/azuread.html#tenant-support) for details concerning multitenant authentication.
### 3. Create a secret
When viewing the newly-created app registration, click the "Add a certificate or secret" link under "Client credentials". Under the "Client secrets" tab, click the "New client secret" button.
You can optionally specify a description and select a lifetime for the secret.
Restart the NetBox services so that the new configuration takes effect. This is typically done with the command below:
```no-highlight
sudo systemctl restart netbox
```
## Testing
Log out of NetBox if already authenticated, and click the "Log In" button at top right. You should see the normal login form as well as an option to authenticate using Azure AD. Click that link.
You should be redirected to Microsoft's authentication portal. Enter the username/email and password of your test account to continue. You may also be prompted to grant this application access to your account.
If successful, you will be redirected back to the NetBox UI, and will be logged in as the AD user. You can verify this by navigating to your profile (using the button at top right).
This user account has been replicated locally to NetBox, and can now be assigned groups and permissions within the NetBox admin UI.
## Troubleshooting
### Redirect URI does not Match
Azure requires that the authenticating client request a redirect URI that matches what you've configured for the app in step two. This URI **must** begin with `https://` (unless using `localhost` for the domain).
If Azure complains that the requested URI starts with `http://` (not HTTPS), it's likely that your HTTP server is misconfigured or sitting behind a load balancer, so NetBox is not aware that HTTPS is being use. To force the use of an HTTPS redirect URI, set `SOCIAL_AUTH_REDIRECT_IS_HTTPS = True` in `configuration.py` per the [python-social-auth docs](https://python-social-auth.readthedocs.io/en/latest/configuration/settings.html#processing-redirects-and-urlopen).
### Not Logged in After Authenticating
If you are redirected to the NetBox UI after authenticating successfully, but are _not_ logged in, double-check the configured backend and app registration. The instructions in this guide pertain only to the `azuread.AzureADOAuth2` backend using a single-tenant app registration.
This guide explains how to configure single sign-on (SSO) support for NetBox using [Okta](https://www.okta.com/) as an authentication backend.
## Okta Configuration
!!! tip "Okta developer account"
Okta offers free developer accounts at <https://developer.okta.com/>.
### 1. Create a test user (optional)
Create a new user in the Okta admin portal to be used for testing. You can skip this step if you already have a suitable account created.
### 2. Create an app registration
Within the Okta administration dashboard, navigate to **Applications > Applications**, and click the "Create App Integration" button. Select "OIDC" as the sign-in method, and "Web application" for the application type.
On the next page, give the app integration a name (e.g. "NetBox") and specify the sign-in and sign-out URIs. These URIs should follow the formats below:
Restart the NetBox services so that the new configuration takes effect. This is typically done with the command below:
```no-highlight
sudo systemctl restart netbox
```
## Testing
Log out of NetBox if already authenticated, and click the "Log In" button at top right. You should see the normal login form as well as an option to authenticate using Okta. Click that link.
You should be redirected to Okta's authentication portal. Enter the username/email and password of your test account to continue. You may also be prompted to grant this application access to your account.
If successful, you will be redirected back to the NetBox UI, and will be logged in as the Okta user. You can verify this by navigating to your profile (using the button at top right).
This user account has been replicated locally to NetBox, and can now be assigned groups and permissions within the NetBox admin UI.
Local user accounts and groups can be created in NetBox under the "Authentication and Authorization" section of the administrative user interface. This interface is available only to users with the "staff" permission enabled.
At a minimum, each user account must have a username and password set. User accounts may also denote a first name, last name, and email address. [Permissions](../permissions.md) may also be assigned to users and/or groups within the admin UI.
## Remote Authentication
NetBox may be configured to provide user authenticate via a remote backend in addition to local authentication. This is done by setting the `REMOTE_AUTH_BACKEND` configuration parameter to a suitable backend class. NetBox provides several options for remote authentication.
NetBox includes an authentication backend which supports LDAP. See the [LDAP installation docs](../../installation/6-ldap.md) for more detail about this backend.
Another option for remote authentication in NetBox is to enable HTTP header-based user assignment. The front end HTTP server (e.g. nginx or Apache) performs client authentication as a process external to NetBox, and passes information about the authenticated user via HTTP headers. By default, the user is assigned via the `REMOTE_USER` header, but this can be customized via the `REMOTE_AUTH_HEADER` configuration parameter.
NetBox supports single sign-on authentication via the [python-social-auth](https://github.com/python-social-auth) library. To enable SSO, specify the path to the desired authentication backend within the `social_core` Python package. Please see the complete list of [supported authentication backends](https://github.com/python-social-auth/social-core/tree/master/social_core/backends) for the available options.
Most remote authentication backends require some additional configuration through settings prefixed with `SOCIAL_AUTH_`. These will be automatically imported from NetBox's `configuration.py` file. Additionally, the [authentication pipeline](https://python-social-auth.readthedocs.io/en/latest/pipeline.html) can be customized via the `SOCIAL_AUTH_PIPELINE` parameter.
NetBox v3.2.3 and later support native integration with [Sentry](https://sentry.io/) for automatic error reporting. To enable this functionality, simply set `SENTRY_ENABLED` to True in `configuration.py`. Errors will be sent to a Sentry ingestor maintained by the NetBox team for analysis.
```python
SENTRY_ENABLED=True
```
### Using a Custom DSN
If you prefer instead to use your own Sentry ingestor, you'll need to first create a new project under your Sentry account to represent your NetBox deployment and obtain its corresponding data source name (DSN). This looks like a URL similar to the example below:
```
https://examplePublicKey@o0.ingest.sentry.io/0
```
Once you have obtained a DSN, configure Sentry in NetBox's `configuration.py` file with the following parameters:
You can optionally attach one or more arbitrary tags to the outgoing error reports if desired by setting the `SENTRY_TAGS` parameter:
```python
SENTRY_TAGS={
"custom.foo":"123",
"custom.bar":"abc",
}
```
!!! warning "Reserved tag prefixes"
Avoid using any tag names which begin with `netbox.`, as this prefix is reserved by the NetBox application.
### Testing
Once the configuration has been saved, restart the NetBox service.
To test Sentry operation, try generating a 404 (page not found) error by navigating to an invalid URL, such as `https://netbox/404-error-testing`. (Be sure that debug mode has been disabled.) After receiving a 404 response from the NetBox server, you should see the issue appear shortly in Sentry.
NetBox includes a `housekeeping` management command that should be run nightly. This command handles:
* Clearing expired authentication sessions from the database
* Deleting changelog records older than the configured [retention time](../configuration/dynamic-settings.md#changelog_retention)
* Deleting job result records older than the configured [retention time](../configuration/dynamic-settings.md#jobresult_retention)
This command can be invoked directly, or by using the shell script provided at `/opt/netbox/contrib/netbox-housekeeping.sh`. This script can be linked from your cron scheduler's daily jobs directory (e.g. `/etc/cron.daily`) or referenced directly within the cron configuration file.
On Debian-based systems, be sure to omit the `.sh` file extension when linking to the script from within a cron directory. Otherwise, the task may not run.
The `housekeeping` command can also be run manually at any time: Running the command outside scheduled execution times will not interfere with its operation.

Object-based permissions enable an administrator to grant users or groups the ability to perform an action on arbitrary subsets of objects in NetBox, rather than all objects of a certain type. For example, it is possible to grant a user permission to view only sites within a particular region, or to modify only VLANs with a numeric ID within a certain range.

When replicating a production database for development purposes, you may find it convenient to exclude changelog data, which can easily account for the bulk of a database's size. To do this, exclude the `extras_objectchange` table data from the export. The table will still be included in the output file, but will not be populated with any data.
These configuration parameters are primarily controlled via NetBox's admin interface (under Admin > Extras > Configuration Revisions). These setting may also be overridden in `configuration.py`; this will prevent them from being modified via the UI.

Some static choice fields on models can be configured with custom values. This is done by defining `FIELD_CHOICES` as a dictionary mapping model fields to their choices. Each choice in the list must have a database value and a human-friendly label, and may optionally specify a color. (A list of available colors is provided below.)
The choices provided can either replace the stock choices provided by NetBox, or append to them. To _replace_ the available choices, specify the app, model, and field name separated by dots. For example, the site model would be referenced as `dcim.Site.status`. To _extend_ the available choices, append a plus sign to the end of this string (e.g. `dcim.Site.status+`).
For example, the following configuration would replace the default site status choices with the options Foo, Bar, and Baz:
```python
FIELD_CHOICES = {
'dcim.Site.status': (
('foo', 'Foo', 'red'),
('bar', 'Bar', 'green'),
('baz', 'Baz', 'blue'),
)
}
```
Appending a plus sign to the field identifier would instead _add_ these choices to the ones already offered:

## Running Custom Scripts
!!! note
To run a custom script, a user must be assigned the `extras.run_script` permission. This is achieved by assigning the user (or group) a permission on the Script object and specifying the `run` action in the admin UI as shown below.
### Via the Web UI
Custom scripts can be run via the web UI by navigating to the script, completing any required form data, and clicking the "run script" button.
### Via the API
To run a script via the REST API, issue a POST request to the script's endpoint specifying the form data and commitment. For example, to run a script named `example.MyReport`, we would make a request such as the following:
The required ``<module>.<script>`` argument is the script to run where ``<module>`` is the name of the python file in the ``scripts`` directory without the ``.py`` extension and ``<script>`` is the name of the script class in the ``<module>`` to run.

@@ -269,7 +323,6 @@ class NewBranchScript(Script):
NetBox validates every object prior to it being written to the database to ensure data integrity. This validation includes things like checking for proper formatting and that references to related objects are valid. However, you may wish to supplement this validation with some rules of your own. For example, perhaps you require that every site's name conforms to a specific pattern. This can be done using custom validation rules.
## Custom Validation Rules
Custom validation rules are expressed as a mapping of model attributes to a set of rules to which that attribute must conform. For example:
```json
{
"name":{
"min_length":5,
"max_length":30
}
}
```
This defines a custom validator which checks that the length of the `name` attribute for an object is at least five characters long, and no longer than 30 characters. This validation is executed _after_ NetBox has performed its own internal validation.
The `CustomValidator` class supports several validation types:
*`min`: Minimum value
*`max`: Maximum value
*`min_length`: Minimum string length
*`max_length`: Maximum string length
*`regex`: Application of a [regular expression](https://en.wikipedia.org/wiki/Regular_expression)
*`required`: A value must be specified
*`prohibited`: A value must _not_ be specified
The `min` and `max` types should be defined for numeric values, whereas `min_length`, `max_length`, and `regex` are suitable for character strings (text values). The `required` and `prohibited` validators may be used for any field, and should be passed a value of `True`.
!!! warning
Bear in mind that these validators merely supplement NetBox's own validation: They will not override it. For example, if a certain model field is required by NetBox, setting a validator for it with `{'prohibited': True}` will not work.
### Custom Validation Logic
There may be instances where the provided validation types are insufficient. NetBox provides a `CustomValidator` class which can be extended to enforce arbitrary validation logic by overriding its `validate()` method, and calling `fail()` when an unsatisfactory condition is detected.
self.fail("Active sites must have a description set!",field='status')
```
The `fail()` method may optionally specify a field with which to associate the supplied error message. If specified, the error message will appear to the user as associated with this field. If omitted, the error message will not be associated with any field.
## Assigning Custom Validators
Custom validators are associated with specific NetBox models under the [CUSTOM_VALIDATORS](../configuration/dynamic-settings.md#custom_validators) configuration parameter. There are three manners by which custom validation rules can be defined:
1. Plain JSON mapping (no custom logic)
2. Dotted path to a custom validator class
3. Direct reference to a custom validator class
### Plain Data
For cases where custom logic is not needed, it is sufficient to pass validation rules as plain JSON-compatible objects. This approach typically affords the most portability for your configuration. For instance:
```python
CUSTOM_VALIDATORS={
"dcim.site":[
{
"name":{
"min_length":5,
"max_length":30,
}
}
],
"dcim.device":[
{
"platform":{
"required":True,
}
}
]
}
```
### Dotted Path
In instances where a custom validator class is needed, it can be referenced by its Python path (relative to NetBox's working directory):
```python
CUSTOM_VALIDATORS={
'dcim.site':(
'my_validators.Validator1',
'my_validators.Validator2',
),
'dcim.device':(
'my_validators.Validator3',
)
}
```
### Direct Class Reference
This approach requires each class being instantiated to be imported directly within the Python configuration file.
When it is necessary to provide authentication credentials (such as when [`LOGIN_REQUIRED`](../configuration/optional-settings.md#login_required) has been enabled), it is recommended to render export templates via the REST API. This allows the client to specify an authentication token. To render an export template via the REST API, make a `GET` request to the model's list endpoint and append the `export` parameter specifying the export template name. For example:
```
GET /api/dcim/sites/?export=MyTemplateName
```
Note that the body of the response will contain only the rendered export template content, as opposed to a JSON object or list.
## Example
Here's an example device export template that will generate a simple Nagios configuration from a list of devices.
```
{% for device in queryset %}{% if device.status and device.primary_ip %}define host{
use generic-switch
host_name {{ device.name }}

Once a report has been run, its associated results will be included in the report view.
Reports can be run via the web UI by navigating to the report and clicking the "run report" button at top right. Once a report has been run, its associated results will be included in the report view.
Models within each app are stored in either `models.py` or within a submodule under the `models/` directory. When creating a model, be sure to subclass the [appropriate base model](models.md) from `netbox.models`. This will typically be NetBoxModel or OrganizationalModel. Remember to add the model class to the `__all__` listing for the module.
Each model should define, at a minimum:
* A `Meta` class specifying a deterministic ordering (if ordered by fields other than the primary ID)
* A `__str__()` method returning a user-friendly string representation of the instance
* A `get_absolute_url()` method returning an instance's direct URL (using `reverse()`)
## 2. Define field choices
If the model has one or more fields with static choices, define those choices in `choices.py` by subclassing `utilities.choices.ChoiceSet`.
## 3. Generate database migrations
Once your model definition is complete, generate database migrations by running `manage.py makemigrations -n $NAME --no-header`. Always specify a short unique name when generating migrations.
!!! info "Configuration Required"
Set `DEVELOPER = True` in your NetBox configuration to enable the creation of new migrations.
## 4. Add all standard views
Most models will need view classes created in `views.py` to serve the following operations:
* List view
* Detail view
* Edit view
* Delete view
* Bulk import
* Bulk edit
* Bulk delete
## 5. Add URL paths
Add the relevant URL path for each view created in the previous step to `urls.py`.
## 6. Add relevant forms
Depending on the type of model being added, you may need to define several types of form classes. These include:
* A base model form (for creating/editing individual objects)
* A bulk edit form
* A bulk import form (for CSV-based import)
* A filterset form (for filtering the object list view)
## 7. Create the FilterSet
Each model should have a corresponding FilterSet class defined. This is used to filter UI and API queries. Subclass the appropriate class from `netbox.filtersets` that matches the model's parent class.
## 8. Create the table class
Create a table class for the model in `tables.py` by subclassing `utilities.tables.BaseTable`. Under the table's `Meta` class, be sure to list both the fields and default columns.
## 9. Create the object template
Create the HTML template for the object view. (The other views each typically employ a generic template.) This template should extend `generic/object.html`.
## 10. Add the model to the navigation menu
Add the relevant navigation menu items in `netbox/netbox/navigation_menu.py`.
## 11. REST API components
Create the following for each model:
* Detailed (full) model serializer in `api/serializers.py`
* Nested serializer in `api/nested_serializers.py`
* API view in `api/views.py`
* Endpoint route in `api/urls.py`
## 12. GraphQL API components
Create a Graphene object type for the model in `graphql/types.py` by subclassing the appropriate class from `netbox.graphql.types`.
Also extend the schema class defined in `graphql/schema.py` with the individual object and object list fields per the established convention.
## 13. Add tests
Add tests for the following:
* UI views
* API views
* Filter sets
## 14. Documentation
Create a new documentation page for the model in `docs/models/<app_label>/<model_name>.md`. Include this file under the "features" documentation where appropriate.
Also add your model to the index in `docs/development/models.md`.

The value of a store can, however, be modified; e.g. by appending a value to a list. Store values generally do not change once the application has been initialized.
The registry can be inspected by importing `registry` from `extras.registry`.

Below is a list of tasks to consider when adding a new field to a core model.
## 1. Generate and run database migration
## 1. Generate and run database migrations
Django migrations are used to express changes to the database schema. In most cases, Django can generate these automatically, however very complex changes may require manual intervention. Always remember to specify a short but descriptive name when generating a new migration.
[Django migrations](https://docs.djangoproject.com/en/stable/topics/migrations/) are used to express changes to the database schema. In most cases, Django can generate these automatically, however very complex changes may require manual intervention. Always remember to specify a short but descriptive name when generating a new migration.
```
./manage.py makemigrations <app> -n <name>
./manage.py migrate
```
Where possible, try to merge related changes into a single migration. For example, if three new fields are being added to different models within an app, these can be expressed in the same migration. You can merge a new migration with an existing one by combining their `operations` lists.

You can merge a newly generated migration with an existing one by combining their `operations` lists.
!!! note
Migrations can only be merged within a release. Once a new release has been published, its migrations cannot be altered.
!!! warning "Do not alter existing migrations"
Migrations can only be merged within a release. Once a new release has been published, its migrations cannot be altered (other than for the purpose of correcting a bug).
## 2. Add validation logic to `clean()`
If the new field introduces additional validation requirements (beyond what's included with the field itself), implement them in the model's `clean()` method. Remember to call the model's original method using `super()` before or agter your custom validation as appropriate:
If the new field introduces additional validation requirements (beyond what's included with the field itself), implement them in the model's `clean()` method. Remember to call the model's original method using `super()` before or after your custom validation as appropriate:
```
class Foo(models.Model):
def clean(self):
super(DeviceCSVForm, self).clean()
super().clean()
# Custom validation goes here
if self.bar is None:
raise ValidationError()
```
## 3. Add CSV helpers
## 3. Update relevant querysets
Add the name of the new field to `csv_headers` and included a CSV-friendly representation of its data in the model's `to_csv()` method. These will be used when exporting objects in CSV format.
If you're adding a relational field (e.g. `ForeignKey`) and intend to include the data when retrieving a list of objects, be sure to include the field using `prefetch_related()` as appropriate. This will optimize the view and avoid extraneous database queries.
## 4. Update relevant querysets
## 4. Update API serializer
If you're adding a relational field (e.g. `ForeignKey`) and intend to include the data when retreiving a list of objects, be sure to include the field using `prefetch_related()` as appropriate. This will optimize the view and avoid excessive database lookups.
Extend the model's API serializer in `<app>.api.serializers` to include the new field. In most cases, it will not be necessary to also extend the nested serializer, which produces a minimal representation of the model.
## 5. Update API serializer
## 5. Add fields to forms
Extend the model's API serializer in `<app>.api.serializers` to include the new field. In most cases, it will not be necessary to also extend the nested serializer, which produces a minimal represenation of the model.
## 6. Add field to forms
Extend any forms to include the new field as appropriate. Common forms include:
Extend any forms to include the new field(s) as appropriate. These are found under the `forms/` directory within each app. Common forms include:
* **Credit/edit** - Manipulating a single object
* **Bulk edit** - Performing a change on mnay objects at once
* **Bulk edit** - Performing a change on many objects at once
* **CSV import** - The form used when bulk importing objects in CSV format
* **Filter** - Displays the options available for filtering a list of objects (both UI and API)
## 7. Extend object filter set
## 6. Extend object filter set
If the new field should be filterable, add it to the `FilterSet` for the model. If the field should be searchable, remember to reference it in the FilterSet's `search()` method.
If the new field should be filterable, add it to the `FilterSet` for the model. If the field should be searchable, remember to query it in the FilterSet's `search()` method.
## 8. Add column to object table
## 7. Add column to object table
If the new field will be included in the object list view, add a column to the model's table. For simple fields, adding the field name to `Meta.fields` will be sufficient. More complex fields may require explicitly declaring a new column.
If the new field will be included in the object list view, add a column to the model's table. For simple fields, adding the field name to `Meta.fields` will be sufficient. More complex fields may require declaring a custom column. Also add the field name to `default_columns` if the column should be present in the table by default.
## 9. Update the UI templates

* View tests
Be diligent to ensure all of the relevant test suites are adapted or extended as necessary to test any new functionality.
## 10. Update the model's documentation
Each model has a dedicated page in the documentation, at `models/<app>/<model>.md`. Update this file to include any relevant information about the new field.
Getting started with NetBox development is pretty straightforward, and should feel very familiar to anyone with Django development experience. There are a few things you'll need:
* A Linux system or environment
* A PostgreSQL server, which can be installed locally [per the documentation](../installation/1-postgresql.md)
* A Redis server, which can also be [installed locally](../installation/2-redis.md)
* A supported version of Python
### Fork the Repo
Assuming you'll be working on your own fork, your first step will be to fork the [official git repository](https://github.com/netbox-community/netbox). (If you're a maintainer who's going to be working directly with the official repo, skip this step.) Click the "fork" button at top right (be sure that you've logged into GitHub first).
The NetBox project utilizes three persistent git branches to track work:
* `master` - Serves as a snapshot of the current stable release
* `develop` - All development on the upcoming stable release occurs here
* `feature` - Tracks work on an upcoming major release
Typically, you'll base pull requests off of the `develop` branch, or off of `feature` if you're working on a new major release. **Never** merge pull requests into the `master` branch: This branch only ever merges pull requests from the `develop` branch, to effect a new release.
For example, assume that the current NetBox release is v3.1.1. Work applied to the `develop` branch will appear in v3.1.2, and work done under the `feature` branch will be included in the next minor release (v3.2.0).
### Enable Pre-Commit Hooks
NetBox ships with a [git pre-commit hook](https://githooks.com/) script that automatically checks for style compliance and missing database migrations prior to committing changes. This helps avoid erroneous commits that result in CI test failures. You are encouraged to enable it by creating a link to `scripts/git-hooks/pre-commit`:
```no-highlight
$ cd .git/hooks/
$ ln -s ../../scripts/git-hooks/pre-commit
```
### Create a Python Virtual Environment
A [virtual environment](https://docs.python.org/3/tutorial/venv.html) (or "venv" for short) is like a container for a set of Python packages. These allow you to build environments suited to specific projects without interfering with system packages or other projects. When installed per the documentation, NetBox uses a virtual environment in production.
Create a virtual environment using the `venv` Python module:
```no-highlight
$ mkdir ~/.venv
$ python3 -m venv ~/.venv/netbox
```
This will create a directory named `.venv/netbox/` in your home directory, which houses a virtual copy of the Python executable and its related libraries and tooling. When running NetBox for development, it will be run using the Python binary at `~/.venv/netbox/bin/python`.
!!! info "Where to Create Your Virtual Environments"
Keeping virtual environments in `~/.venv/` is a common convention but entirely optional: Virtual environments can be created almost wherever you please. Also consider using [`virtualenvwrapper`](https://virtualenvwrapper.readthedocs.io/en/stable/) to simplify the management of multiple venvs.
Once created, activate the virtual environment:
```no-highlight
$ source ~/.venv/netbox/bin/activate
(netbox) $
```
Notice that the console prompt changes to indicate the active environment. This updates the necessary system environment variables to ensure that any Python scripts are run within the virtual environment.
### Install Dependencies
With the virtual environment activated, install the project's required Python packages using the `pip` module:
* `REDIS`: Redis configuration, if different from the defaults
* `SECRET_KEY`: Set to a random string (use `generate_secret_key.py` in the parent directory to generate a suitable key)
* `DEBUG`: Set to `True`
* `DEVELOPER`: Set to `True` (this enables the creation of new database migrations)
### Start the Development Server
Django provides a lightweight, auto-updating HTTP/WSGI server for development use. It is started with the `runserver` management command:
```no-highlight
$ ./manage.py runserver
Watching for file changes with StatReloader
Performing system checks...
System check identified no issues (0 silenced).
February 18, 2022 - 20:29:57
Django version 4.0.2, using settings 'netbox.settings'
Starting development server at http://127.0.0.1:8000/
Quit the server with CONTROL-C.
```
This ensures that your development environment is now complete and operational. Any changes you make to the code base will be automatically adapted by the development server.
!!! info "IDE Integration"
Some IDEs, such as PyCharm, will integrate with Django's development server and allow you to run it directly within the IDE. This is strongly encouraged as it makes for a much more convenient development environment.
## Populating Demo Data
Once you have your development environment up and running, it might be helpful to populate some "dummy" data to make interacting with the UI and APIs more convenient. Check out the [netbox-demo-data](https://github.com/netbox-community/netbox-demo-data) repo on GitHub, which houses a collection of sample data that can be easily imported to any new NetBox deployment. (This sample data is used to populate the public demo instance at <https://demo.netbox.dev>.)
The demo data is provided in JSON format and loaded into an empty database using Django's `loaddata` management command. Consult the demo data repo's `README` file for complete instructions on populating the data.
## Running Tests
Prior to committing any substantial changes to the code base, be sure to run NetBox's test suite to catch any potential errors. Tests are run using the `test` management command, which employs Python's [`unittest`](https://docs.python.org/3/library/unittest.html#module-unittest) library. Remember to ensure the Python virtual environment is active before running this command. Also keep in mind that these commands are executed in the `netbox/` directory, not the root directory of the repository.
To avoid potential issues with your local configuration file, set the `NETBOX_CONFIGURATION` to point to the packaged test configuration at `netbox/configuration_testing.py`. This will handle things like ensuring that the dummy plugin is enabled for comprehensive testing.
In cases where you haven't made any changes to the database schema (which is typical), you can append the `--keepdb` argument to this command to reuse the test database between runs. This cuts down on the time it takes to run the test suite since the database doesn't have to be rebuilt each time. (Note that this argument will cause errors if you've modified any model fields since the previous test run.)
```no-highlight
$ python manage.py test --keepdb
```
You can also reduce testing time by enabling parallel test execution with the `--parallel` flag. (By default, this will run as many parallel tests as you have processors. To avoid sluggishness, it's a good idea to specify a lower number of parallel tests.) This flag can be combined with `--keepdb`, although if you encounter any strange errors, try running the test suite again with parallelization disabled.
```no-highlight
$ python manage.py test --parallel <n>
```
Finally, it's possible to limit the run to a specific set of tests, specified by their Python path. For example, to run only IPAM and DCIM view tests:
```no-highlight
$ python manage.py test dcim.tests.test_views ipam.tests.test_views
```
This is handy for instances where just a few tests are failing and you want to re-run them individually.
## Submitting Pull Requests
Once you're happy with your work and have verified that all tests pass, commit your changes and push it upstream to your fork. Always provide descriptive (but not excessively verbose) commit messages. When working on a specific issue, be sure to prefix your commit message with the word "Fixes" or "Closes" and the issue number (with a hash mark). This tells GitHub to automatically close the referenced issue once the commit has been merged.
```no-highlight
$ git commit -m "Closes #1234: Add IPv5 support"
$ git push origin
```
Once your fork has the new commit, submit a [pull request](https://github.com/netbox-community/netbox/compare) to the NetBox repo to propose the changes. Be sure to provide a detailed accounting of the changes being made and the reasons for doing so.
Once submitted, a maintainer will review your pull request and either merge it or request changes. If changes are needed, you can make them via new commits to your fork: The pull request will update automatically.
!!! note "Remember to Open an Issue First"
Remember, pull requests are permitted only for **accepted** issues. If an issue you want to work on hasn't been approved by a maintainer yet, it's best to avoid risking your time and effort on a change that might not be accepted. (The one exception to this is trivial changes to the documentation or other non-critical resources.)

## Communication
Communication among developers should always occur via public channels:
There are several official forums for communication among the developers and community members:
* [GitHub issues](https://github.com/netbox-community/netbox/issues) - All feature requests, bug reports, and other substantial changes to the code base **must** be documented in an issue.
* [The mailing list](https://groups.google.com/forum/#!forum/netbox-discuss) - The preferred forum for general discussion and support issues. Ideal for shaping a feature request prior to submitting an issue.
* [#netbox on NetworkToCode](http://slack.networktocode.com/) - Good for quick chats. Avoid any discussion that might need to be referenced later on, as the chat history is not retained long.
* [GitHub issues](https://github.com/netbox-community/netbox/issues) - All feature requests, bug reports, and other substantial changes to the code base **must** be documented in a GitHub issue.
* [GitHub discussions](https://github.com/netbox-community/netbox/discussions) - The preferred forum for general discussion and support issues. Ideal for shaping a feature request prior to submitting an issue.

## Governance
NetBox follows the [benevolent dictator](http://oss-watch.ac.uk/resources/benevolentdictatorgovernancemodel) model of governance, with [Jeremy Stretch](https://github.com/jeremystretch) ultimately responsible for all changes to the code base. While community contributions are welcomed and encouraged, the lead maintainer's primary role is to ensure the project's long-term maintainability and continued focus on its primary functions (in other words, avoid scope creep).

While community contributions are welcomed and encouraged, the lead maintainer's primary role is to ensure the project's long-term maintainability and continued focus on its primary functions.
## Project Structure
All development of the current NetBox release occurs in the `develop` branch; releases are packaged from the `master` branch. The `master` branch should _always_ represent the current stable release in its entirety, such that installing NetBox by either downloading a packaged release or cloning the `master` branch provides the same code base.

Only pull requests representing new releases should be merged into `master`.
NetBox components are arranged into functional subsections called _apps_ (a carryover from Django verancular). Each app holds the models, views, and templates relevant to a particular function:
NetBox components are arranged into Django apps. Each app holds the models, views, and other resources relevant to a particular function:
*`circuits`: Communications circuits and providers (not to be confused with power circuits)
*`dcim`: Datacenter infrastructure management (sites, racks, and devices)
*`extras`: Additional features not considered part of the core data model
*`ipam`: IP address management (VRFs, prefixes, IP addresses, and VLANs)
*`secrets`: Encrypted storage of sensitive data (e.g. login credentials)
*`tenancy`: Tenants (such as customers) to which NetBox objects may be assigned
*`users`: Authentication and user preferences
*`utilities`: Resources which are not user-facing (extendable classes, etc.)
*`virtualization`: Virtual machines and clusters
*`wireless`: Wireless links and LANs
All core functionality is stored within the `netbox/` subdirectory. HTML templates are stored in a common `templates/` directory, with model- and view-specific templates arranged by app. Documentation is kept in the `docs/` root directory.
A NetBox model represents a discrete object type such as a device or IP address. Each model is defined as a Python class and has its own SQL table. All NetBox data models can be categorized by type.
The Django [content types](https://docs.djangoproject.com/en/stable/ref/contrib/contenttypes/) framework can be used to reference models within the database. A ContentType instance references a model by its `app_label` and `name`: For example, the Site model is referred to as `dcim.site`. The content type combined with an object's primary key form a globally unique identifier for the object (e.g. `dcim.site:123`).
### Features Matrix
* [Change logging](../additional-features/change-logging.md) - Changes to these objects are automatically recorded in the change log
* [Webhooks](../additional-features/webhooks.md) - NetBox is capable of generating outgoing webhooks for these objects
* [Custom fields](../customization/custom-fields.md) - These models support the addition of user-defined fields
* [Export templates](../customization/export-templates.md) - Users can create custom export templates for these models
* [Tagging](../models/extras/tag.md) - The models can be tagged with user-defined tags
* [Journaling](../additional-features/journaling.md) - These models support persistent historical commentary
* Nesting - These models can be nested recursively to create a hierarchy
Required Python packages are maintained in two files. `base_requirements.txt` contains a list of all the packages required by NetBox. Some of them may be pinned to a specific version of the package due to a known issue. For example:
Check `base_requirements.txt` for any dependencies pinned to a specific version, and upgrade them to their most stable release (where possible).
The other file is `requirements.txt`, which lists each of the required packages pinned to its current stable version. When NetBox is installed, the Python environment is configured to match this file. This helps ensure that a new release of a dependency doesn't break NetBox.
Every minor version release should refresh `requirements.txt` so that it lists the most recent stable release of each package. To do this:
1. Create a new virtual environment.
2. Install the latest version of all required packages via pip:
```
pip install -U -r base_requirements.txt
```
3. Run all tests and check that the UI and API function as expected.
4. Update the package versions in `requirements.txt` as appropriate.
### Update Static Libraries
Update the following static libraries to their most recent stable release:
* Bootstrap 3
* Font Awesome 4
* Select2
* jQuery

The other file is `requirements.txt`, which lists each of the required packages pinned to its current stable version. When NetBox is installed, the Python environment is configured to match this file. This helps ensure that a new release of a dependency doesn't break NetBox.
Every release should refresh `requirements.txt` so that it lists the most recent stable release of each package. To do this:
1. Create a new virtual environment.

3. Run all tests and check that the UI and API function as expected.
4. Review each requirement's release notes for any breaking or otherwise noteworthy changes.
5. Update the package versions in `requirements.txt` as appropriate.
In cases where upgrading a dependency to its most recent release is breaking, it should be pinned to its current minor version in `base_requirements.txt` (with an explanatory comment) and revisited for the next major NetBox release.

## General Guidance
* When in doubt, remain consistent: It is better to be consistently incorrect than inconsistently correct. If you notice in the course of unrelated work a pattern that should be corrected, continue to follow the pattern for now and open a bug so that the entire code base can be evaluated at a later point.

If you notice in the course of unrelated work a pattern that should be corrected, continue to follow the pattern for now and submit a separate bug report so that the entire code base can be evaluated at a later point.
* Prioritize readability over concision. Python is a very flexible language that typically gives us several options for expressing a given piece of logic, but some may be more friendly to the reader than others. (List comprehensions are particularly vulnerable to over-optimization.) Always remain considerate of the future reader who may need to interpret your code without the benefit of the context within which you are writing it.

Utility views are reusable views that handle common CRUD tasks, such as listing and updating objects. Some views operate on individual objects, whereas others (referred to as "bulk" views) operate on multiple objects at once.
## Individual Views
### ObjectView
Retrieve and display a single object.
### ObjectListView
Generates a paginated table of objects from a given queryset, which may optionally be filtered.
### ObjectEditView
Updates an object identified by a primary key (PK) or slug. If no existing object is specified, a new object will be created.
### ObjectDeleteView
Deletes an object. The user is redirected to a confirmation page before the deletion is executed.
## Bulk Views
### BulkCreateView
Creates multiple objects at once based on a given pattern. Currently used only for IP addresses.
### BulkImportView
Accepts CSV-formatted data and creates a new object for each line. Creation is all-or-none.
### BulkEditView
Applies changes to multiple objects at once in a two-step operation. First, the list of PKs for selected objects is POSTed and an edit form is presented to the user. On submission of that form, the specified changes are made to all selected objects.
### BulkDeleteView
Deletes multiple objects. The user selects the objects to be deleted and confirms the deletion.
## Component Views
### ComponentCreateView
Create one or more component objects beloning to a parent object (e.g. interfaces attached to a device).
### ComponentEditView
A subclass of `ObjectEditView`: Updates an individual component object.
### ComponentDeleteView
A subclass of `ObjectDeleteView`: Deletes an individual component object.
### BulkComponentCreateView
Create a set of components objects for each of a selected set of parent objects. This view can be used e.g. to create multiple interfaces on multiple devices at once.

### Styling & HTML Elements
#### [Bootstrap](https://getbootstrap.com/) 5
The majority of the NetBox UI is made up of stock Bootstrap components, with some styling modifications and custom components added on an as-needed basis. Bootstrap uses [Sass](https://sass-lang.com/), and NetBox extends Bootstrap's core Sass files for theming and customization.
All client-side scripting is transpiled from TypeScript to JavaScript and served by Django. In development, TypeScript is an _extremely_ effective tool for accurately describing and checking the code, which leads to significantly fewer bugs, a better development experience, and more predictable/readable code.
As part of the [bundling](#bundling) process, Bootstrap's JavaScript plugins are imported and bundled alongside NetBox's front-end code.
!!! danger "NetBox is jQuery-free"
Following the Bootstrap team's deprecation of jQuery in Bootstrap 5, NetBox also no longer uses jQuery in front-end code.
## Guidance
NetBox generally follows the following guidelines for front-end code:
- Bootstrap utility classes may be used to solve one-off issues or to implement singular components, as long as the class list does not exceed 4-5 classes. If an element needs more than 5 utility classes, a custom SCSS class should be added that contains the required style properties.
- Custom classes must be commented, explaining the general purpose of the class and where it is used.
- Reuse SCSS variables whenever possible. CSS values should (almost) never be hard-coded.
- All TypeScript functions must have, at a minimum, a basic [JSDoc](https://jsdoc.app/) description of what the function is for and where it is used. If possible, document all function arguments via [`@param` JSDoc block tags](https://jsdoc.app/tags-param.html).
- Expanding on NetBox's [dependency policy](style-guide.md#introducing-new-dependencies), new front-end dependencies should be avoided unless absolutely necessary. Every new front-end dependency adds to the CSS/JavaScript file size that must be loaded by the client and this should be minimized as much as possible. If adding a new dependency is unavoidable, use a tool like [Bundlephobia](https://bundlephobia.com/) to ensure the smallest possible library is used.
- All UI elements must be usable on all common screen sizes, including mobile devices. Be sure to test newly implemented solutions (JavaScript included) on as many screen sizes and device types as possible.
- NetBox aligns with Bootstrap's [supported Browsers and Devices](https://getbootstrap.com/docs/5.1/getting-started/browsers-devices/) list.
## UI Development
To contribute to the NetBox UI, you'll need to review the main [Getting Started guide](getting-started.md) in order to set up your base environment.
### Tools
Once you have a working NetBox development environment, you'll need to install a few more tools to work with the NetBox UI:
- [NodeJS](https://nodejs.org/en/download/) (the LTS release should suffice)
After Node and Yarn are installed on your system, you'll need to install all the NetBox UI dependencies:
```console
$cd netbox/project-static
$ yarn
```
!!! warning "Check Your Working Directory"
You need to be in the `netbox/project-static` directory to run the below `yarn` commands.
### Bundling
In order for the TypeScript and Sass (SCSS) source files to be usable by a browser, they must first be transpiled (TypeScript → JavaScript, Sass → CSS), bundled, and minified. After making changes to TypeScript or Sass source files, run `yarn bundle`.
`yarn bundle` is a wrapper around the following subcommands, any of which can be run individually:
All output files will be written to `netbox/project-static/dist`, where Django will pick them up when `manage.py collectstatic` is run.
!!! info "Remember to re-run `manage.py collectstatic`"
If you're running the development web server — `manage.py runserver` — you'll need to run `manage.py collectstatic` to see your changes.
### Linting, Formatting & Type Checking
Before committing any changes to TypeScript files, and periodically throughout the development process, you should run `yarn validate` to catch formatting, code quality, or type errors.
!!! tip "IDE Integrations"
If you're using an IDE, it is strongly recommended to install [ESLint](https://eslint.org/docs/user-guide/integrations), [TypeScript](https://github.com/Microsoft/TypeScript/wiki/TypeScript-Editor-Support), and [Prettier](https://prettier.io/docs/en/editors.html) integrations, if available. Most of them will automatically check and/or correct issues in the code as you develop, which can significantly increase your productivity as a contributor.
`yarn validate` is a wrapper around the following subcommands, any of which can be run individually:
NetBox provides a read-only [GraphQL](https://graphql.org/) API to complement its REST API. This API is powered by the [Graphene](https://graphene-python.org/) library and [Graphene-Django](https://docs.graphene-python.org/projects/django/en/latest/).
## Queries
GraphQL enables the client to specify an arbitrary nested list of fields to include in the response. All queries are made to the root `/graphql` API endpoint. For example, to return the circuit ID and provider name of each circuit with an active status, you can issue a request such as the following:
The response will include the requested data formatted as JSON:
```json
{
"data":{
"circuits":[
{
"cid":"1002840283",
"provider":{
"name":"CenturyLink"
}
},
{
"cid":"1002840457",
"provider":{
"name":"CenturyLink"
}
}
]
}
}
```
!!! note
It's recommended to pass the return data through a JSON parser such as `jq` for better readability.
NetBox provides both a singular and plural query field for each object type:
*`$OBJECT`: Returns a single object. Must specify the object's unique ID as `(id: 123)`.
*`$OBJECT_list`: Returns a list of objects, optionally filtered by given parameters.
For example, query `device(id:123)` to fetch a specific device (identified by its unique ID), and query `device_list` (with an optional set of filters) to fetch all devices.
For more detail on constructing GraphQL queries, see the [Graphene documentation](https://docs.graphene-python.org/en/latest/).
## Filtering
The GraphQL API employs the same filtering logic as the UI and REST API. Filters can be specified as key-value pairs within parentheses immediately following the query name. For example, the following will return only sites within the North Carolina region with a status of active:
NetBox's GraphQL API uses the same API authentication tokens as its REST API. Authentication tokens are included with requests by attaching an `Authorization` HTTP header in the following form:
```
Authorization: Token $TOKEN
```
## Disabling the GraphQL API
If not needed, the GraphQL API can be disabled by setting the [`GRAPHQL_ENABLED`](../configuration/dynamic-settings.md#graphql_enabled) configuration parameter to False and restarting NetBox.

NetBox supports Python 3.6 and 3.7 environments currently. (Support for Python 3.5 was removed in NetBox v2.8.)
NetBox supports Python 3.8, 3.9, and 3.10 environments.
## Getting Started
See the [installation guide](installation/index.md) for help getting NetBox up and running quickly.
Minor NetBox releases (e.g. v3.1) are published three times a year; in April, August, and December. These typically introduce major new features and may contain breaking API changes. Patch releases are published roughly every one to two weeks to resolve bugs and fulfill minor feature requests. These are backward-compatible with previous releases unless otherwise noted. The NetBox maintainers strongly recommend running the latest stable release whenever possible.
Please see the [official installation guide](installation/index.md) for detailed instructions on obtaining and installing NetBox.
This section entails the installation and configuration of a local PostgreSQL database. If you already have a PostgreSQL database service in place, skip to [the next section](2-redis.md).
!!! warning
NetBox requires PostgreSQL 9.6 or higher. Please note that MySQL and other relational databases are **not** currently supported.
The installation instructions provided here have been tested to work on Ubuntu 18.04 and CentOS 7.5. The particular commands needed to install dependencies on other distributions may vary significantly. Unfortunately, this is outside the control of the NetBox maintainers. Please consult your distribution's documentation for assistance with any errors.
!!! warning "PostgreSQL 10 or later required"
NetBox requires PostgreSQL 10 or later. Please note that MySQL and other relational databases are **not** supported.
## Installation
#### Ubuntu
=== "Ubuntu"
If a recent enough version of PostgreSQL is not available through your distribution's package manager, you'll need to install it from an official [PostgreSQL repository](https://wiki.postgresql.org/wiki/Apt).
```no-highlight
sudo apt update
sudo apt install -y postgresql
```
=== "CentOS"
```no-highlight
sudo yum install -y postgresql-server
sudo postgresql-setup --initdb
```
CentOS configures ident host-based authentication for PostgreSQL by default. Because NetBox will need to authenticate using a username and password, modify `/var/lib/pgsql/data/pg_hba.conf` to support MD5 authentication by changing `ident` to `md5` for the lines below:
```no-highlight
host all all 127.0.0.1/32 md5
host all all ::1/128 md5
```
Once PostgreSQL has been installed, start the service and enable it to run at boot:
```no-highlight
# apt-get update
# apt-get install -y postgresql libpq-dev
sudo systemctl start postgresql
sudo systemctl enable postgresql
```
#### CentOS
CentOS 7 does not ship with a recent enough version of PostgreSQL, so it will need to be installed from an external repository. The instructions below show the installation of PostgreSQL 9.6, however you may opt to install a more recent version.
Before continuing, verify that you have installed PostgreSQL 10 or later:
CentOS users should modify the PostgreSQL configuration to accept password-based authentication by replacing `ident` with `md5` for all host entries within `/var/lib/pgsql/9.6/data/pg_hba.conf`. For example:
```no-highlight
host all all 127.0.0.1/32 md5
host all all ::1/128 md5
```
Then, start the service and enable it to run at boot:
```no-highlight
# systemctl start postgresql-9.6
# systemctl enable postgresql-9.6
psql -V
```
## Database Creation
At a minimum, we need to create a database for NetBox and assign it a username and password for authentication. This is done with the following commands.
!!! danger
**Do not use the password from the example.** Choose a strong, random password to ensure secure database authentication for your NetBox installation.
At a minimum, we need to create a database for NetBox and assign it a username and password for authentication. Start by invoking the PostgreSQL shell as the system Postgres user.

postgres=# CREATE USER netbox WITH PASSWORD 'J5brHrAXFLQSif0K';
CREATE ROLE
postgres=# GRANT ALL PRIVILEGES ON DATABASE netbox TO netbox;
GRANT
postgres=# \q
sudo -u postgres psql
```
Within the shell, enter the following commands to create the database and user (role), substituting your own value for the password:
```postgresql
CREATE DATABASE netbox;
CREATE USER netbox WITH PASSWORD 'J5brHrAXFLQSif0K';
GRANT ALL PRIVILEGES ON DATABASE netbox TO netbox;
```
!!! danger "Use a strong password"
**Do not use the password from the example.** Choose a strong, random password to ensure secure database authentication for your NetBox installation.
Once complete, enter `\q` to exit the PostgreSQL shell.
## Verify Service Status
You can verify that authentication works issuing the following command and providing the configured password. (Replace `localhost` with your database server if using a remote database.)
You can verify that authentication works by executing the `psql` command and passing the configured username and password. (Replace `localhost` with your database server if using a remote database.)

## Download NetBox
This documentation provides two options for installing NetBox: from a downloadable archive, or from the git repository. Installing from a package (option A below) requires manually fetching and decompressing the archive for every future update, whereas installation via git (option B) allows for seamless upgrades by re-pulling the `master` branch.
This documentation provides two options for installing NetBox: from a downloadable archive, or from the git repository. Installing from a package (option A below) requires manually fetching and extracting the archive for every future update, whereas installation via git (option B) allows for seamless upgrades by re-pulling the `master` branch.
### Option A: Download a Release Archive
Download the [latest stable release](https://github.com/netbox-community/netbox/releases) from GitHub as a tarball or ZIP archive and extract it to your desired path. In this example, we'll use `/opt/netbox` as the NetBox root.
It is recommended to install NetBox in a directory named for its version number. For example, NetBox v2.9.0 would be installed into `/opt/netbox-2.9.0`, and a symlink from `/opt/netbox/` would point to this location. This allows for future releases to be installed in parallel without interrupting the current installation. When changing to the new release, only the symlink needs to be updated.
It is recommended to install NetBox in a directory named for its version number. For example, NetBox v3.0.0 would be installed into `/opt/netbox-3.0.0`, and a symlink from `/opt/netbox/` would point to this location. (You can verify this configuration with the command `ls -l /opt | grep netbox`.) This allows for future releases to be installed in parallel without interrupting the current installation. When changing to the new release, only the symlink needs to be updated.
### Option B: Clone the Git Repository
Create the base directory for the NetBox installation. For this guide, we'll use `/opt/netbox`.
```no-highlight
# mkdir -p /opt/netbox/ && cd /opt/netbox/
sudo mkdir -p /opt/netbox/
cd /opt/netbox/
```
If `git` is not already installed, install it:
#### Ubuntu
=== "Ubuntu"
```no-highlight
# apt-get install -y git
```
```no-highlight
sudo apt install -y git
```
#### CentOS
=== "CentOS"
```no-highlight
# yum install -y git
```
```no-highlight
sudo yum install -y git
```
Next, clone the **master** branch of the NetBox GitHub repository into the current directory. (This branch always holds the current stable release.)
Installation via git also allows you to easily try out development versions of NetBox. The `develop` branch contains all work underway for the next minor release, and the `develop-x.y` branch (if present) tracks progress on the next major release.
The `git clone` command above utilizes a "shallow clone" to retrieve only the most recent commit. If you need to download the entire history, omit the `--depth 1` argument.
The `git clone` command should generate output similar to the following:
Installation via git also allows you to easily try out different versions of NetBox. To check out a [specific NetBox release](https://github.com/netbox-community/netbox/releases), use the `git checkout` command with the desired release tag. For example, `git checkout v3.0.8`.
## Create the NetBox System User
Create a system user account named `netbox`. We'll configure the WSGI and HTTP services to run under this account. We'll also assign this user ownership of the media directory. This ensures that NetBox will be able to save uploaded files.
Move into the NetBox configuration directory and make a copy of `configuration.example.py` named `configuration.py`. This file will hold all of your local configuration parameters.

## Upgrading
If you are upgrading from an existing installation, please consult the [upgrading guide](upgrading.md).
!!! note
Beginning with v2.5.9, the official documentation calls for systemd to be used for managing the WSGI workers in place of supervisord. Please see the instructions for [migrating to systemd](migrating-to-systemd.md) if you are still using supervisord.
Prior to upgrading your NetBox instance, be sure to carefully review all [release notes](../../release-notes/) that have been published since your current version was released. Although the upgrade process typically does not involve additional work, certain releases may introduce breaking or backward-incompatible changes. These are called out in the release notes under the version in which the change went into effect.

!!! info "Checking out an older release"
If you need to upgrade to an older version rather than the current stable release, you can check out any valid [git tag](https://github.com/netbox-community/netbox/tags), each of which represents a release. For example, to checkout the code for NetBox v2.11.11, do:
sudo git checkout v2.11.11
## Run the Upgrade Script
Once the new code is in place, verify that any optional Python packages required by your deployment (e.g. `napalm` or `django-auth-ldap`) are listed in `local_requirements.txt`. Then, run the upgrade script:
```no-highlight
# ./upgrade.sh
sudo ./upgrade.sh
```
This script:
!!! warning
If the default version of Python is not at least 3.8, you'll need to pass the path to a supported Python version as an environment variable when calling the upgrade script. For example:
```no-highlight
sudo PYTHON=/usr/bin/python3.8 ./upgrade.sh
```
This script performs the following actions:
* Destroys and rebuilds the Python virtual environment
* Installs all required Python packages (listed in `requirements.txt`)
* Installs any additional packages from `local_requirements.txt`
* Applies any database migrations that were included in the release
* Builds the documentation locally (for offline use)
* Collects all static files to be served by the HTTP service
* Deletes stale content types from the database
* Deletes all expired user sessions from the database
* Clears all cached data to prevent conflicts with the new release
!!! note
It's possible that the upgrade script will display a notice warning of unreflected database migrations:
Your models have changes that are not yet reflected in a migration, and so won't be applied.
Run 'manage.py makemigrations' to make new migrations, and then re-run 'manage.py migrate' to apply them.
This may occur due to semantic differences in environment, and can be safely ignored. Never attempt to create new migrations unless you are intentionally modifying the database schema.
If the upgrade script prompts a warning about unreflected database migrations, this indicates that some change has
been made to your local codebase and should be investigated. Never attempt to create new migrations unless you are
intentionally modifying the database schema.
## Restart the NetBox Services
!!! warning
If you are upgrading from an installation that does not use a Python virtual environment, you'll need to update the systemd service files to reference the new Python and gunicorn executables before restarting the services. These are located in `/opt/netbox/venv/bin/`. See the example service files in `/opt/netbox/contrib/` for reference.
If you are upgrading from an installation that does not use a Python virtual environment (any release prior to v2.7.9), you'll need to update the systemd service files to reference the new Python and gunicorn executables before restarting the services. These are located in `/opt/netbox/venv/bin/`. See the example service files in `/opt/netbox/contrib/` for reference.
Finally, restart the gunicorn and RQ services:
```no-highlight
# sudo systemctl restart netbox netbox-rq
sudo systemctl restart netbox netbox-rq
```
!!! note
It's possible you are still using supervisord instead of systemd. If so, please see the instructions for [migrating to systemd](migrating-to-systemd.md).
## Verify Housekeeping Scheduling
If upgrading from a release prior to NetBox v3.0, check that a cron task (or similar scheduled process) has been configured to run NetBox's nightly housekeeping command. A shell script which invokes this command is included at `contrib/netbox-housekeeping.sh`. It can be linked from your system's daily cron task directory, or included within the crontab directly. (If NetBox has been installed in a nonstandard path, be sure to update the system paths within this script first.)
