+Related objects (e.g. `ForeignKey` fields) are represented using a nested serializer. A nested serializer provides a minimal representation of an object, including only its URL and enough information to construct its name. When performing write api actions (`POST`, `PUT`, and `PATCH`), any `ForeignKey` relationships do not use the nested serializer, instead you will pass just the integer ID of the related model.  
 
 When a base serializer includes one or more nested serializers, the hierarchical structure precludes it from being used for write operations. Thus, a flat representation of an object may be provided using a writable serializer. This serializer includes only raw database values and is not typically used for retrieval, except as part of the response to the creation or updating of an object.

+## Static Choice Fields
+
+Some model fields, such as the `status` field in the above example, utilize static integers corresponding to static choices. The available choices can be retrieved from the read-only `_choices` endpoint within each app. A specific `model:field` tuple may optionally be specified in the URL.
+
+Each choice includes a human-friendly label and its corresponding numeric value. For example, `GET /api/ipam/_choices/prefix:status/` will return:
+
+```
+[
+    {
+        "value": 0,
+        "label": "Container"

+    },
+    {
+        "value": 3,
+        "label": "Deprecated"
+    }
+]
+```
+
+Thus, to set a prefix's status to "Reserved," it would be assigned the integer `2`.
+
+A request for `GET /api/ipam/_choices/` will return choices for _all_ fields belonging to models within the IPAM app.

The chassis would appear in the rack elevation as a 2U device with four device bays. Each server within it would be defined as a 0U device installed in one of the device bays. Child devices do not appear on rack elevations, but they are included in the "Non-Racked Devices" list within the rack view.

+
+# Virtual Chassis
+
+A virtual chassis represents a set of devices which share a single control plane: for example, a stack of switches which are managed as a single device. Each device in the virtual chassis is assigned a position and (optionally) a priority. Exactly one device is designated the virtual chassis master: This device will typically be assigned a name, secrets, services, and other attributes related to its management.
+
+It's important to recognize the distinction between a virtual chassis and a chassis-based device. For instance, a virtual chassis is not used to model a chassis switch with removable line cards such as the Juniper EX9208, as its line cards are _not_ physically separate devices capable of operating independently.

+NetBox supports the definition of virtual machines arranged in clusters. A cluster can optionally have physical host devices associated with it.
+
+# Clusters
+
+A cluster is a logical grouping of physical resources within which virtual machines run. A cluster must be assigned a type, and may optionally be assigned an organizational group.
+
+Physical devices (from NetBox's DCIM component) may be associated with clusters as hosts. This allows users to track on which host(s) a particular VM may reside. However, NetBox does not support pinning a specific VM within a cluster to a particular host device.
+
+### Cluster Types
+
+A cluster type represents a technology or mechanism by which a cluster is formed. For example, you might create a cluster type named "VMware vSphere" for a locally hosted cluster or "DigitalOcean NYC3" for one hosted by a cloud provider.
+
+### Cluster Groups
+
+Cluster groups may be created for the purpose of organizing clusters.
+
+---
+
+# Virtual Machines
+
+A virtual machine represents a virtual compute instance hosted within a cluster. Each VM must be associated with exactly one cluster.
+
+Like devices, each VM can have interfaces created on it. These behave similarly to device interfaces, and can be assigned IP addresses, however given their virtual nature they cannot be connected to other interfaces. VMs can also be assigned layer four services. Unlike physical devices, VMs cannot be assigned console or power ports, or device bays.
+
+The following resources can be defined for each VM:
+
+* vCPU count
+* Memory (MB)
+* Disk space (GB)

+# Utility Views
+
+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
+
+### 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.

+# NetBox Reports
+
+A NetBox report is a mechanism for validating the integrity of data within NetBox. Running a report allows the user to verify that the objects defined within NetBox meet certain arbitrary conditions. For example, you can write reports to check that:
+
+* All top-of-rack switches have a console connection
+* Every router has a loopback interface with an IP address assigned
+* Each interface description conforms to a standard format
+* Every site has a minimum set of VLANs defined
+* All IP addresses have a parent prefix
+
+...and so on. Reports are completely customizable, so there's practically no limit to what you can test for.
+
+## Writing Reports
+
+Reports must be saved as files in the [`REPORTS_ROOT`](../configuration/optional-settings/#reports_root) path (which defaults to `netbox/reports/`). Each file created within this path is considered a separate module. Each module holds one or more reports (Python classes), each of which performs a certain function. The logic of each report is broken into discrete test methods, each of which applies a small portion of the logic comprising the overall test.
+
+!!! warning
+    The reports path includes a file named `__init__.py`, which registers the path as a Python module. Do not delete this file.
+
+For example, we can create a module named `devices.py` to hold all of our reports which pertain to devices in NetBox. Within that module, we might define several reports. Each report is defined as a Python class inheriting from `extras.reports.Report`.
+
+```
+from extras.reports import Report
+
+class DeviceConnectionsReport(Report):
+    description = "Validate the minimum physical connections for each device"
+
+class DeviceIPsReport(Report):
+    description = "Check that every device has a primary IP address assigned"
+```
+
+Within each report class, we'll create a number of test methods to execute our report's logic. In DeviceConnectionsReport, for instance, we want to ensure that every live device has a console connection, an out-of-band management connection, and two power connections.
+
+```
+from dcim.constants import CONNECTION_STATUS_PLANNED, STATUS_ACTIVE
+from dcim.models import ConsolePort, Device, PowerPort
+from extras.reports import Report
+
+
+class DeviceConnectionsReport(Report):
+    description = "Validate the minimum physical connections for each device"
+
+    def test_console_connection(self):
+
+        # Check that every console port for every active device has a connection defined.
+        for console_port in ConsolePort.objects.select_related('device').filter(device__status=STATUS_ACTIVE):

+                self.log_failure(
+                    console_port.device,
+                    "No console connection defined for {}".format(console_port.name)
+                )
+            elif console_port.connection_status == CONNECTION_STATUS_PLANNED:

+
+As you can see, reports are completely customizable. Validation logic can be as simple or as complex as needed.
+
+!!! warning
+    Reports should never alter data: If you find yourself using the `create()`, `save()`, `update()`, or `delete()` methods on objects within reports, stop and re-evaluate what you're trying to accomplish. Note that there are no safeguards against the accidental alteration or destruction of data.
+
+The following methods are available to log results within a report:
+
+* log(message)
+* log_success(object, message=None)
+* log_info(object, message)
+* log_warning(object, message)
+* log_failure(object, message)
+
+The recording of one or more failure messages will automatically flag a report as failed. It is advised to log a success for each object that is evaluated so that the results will reflect how many objects are being reported on. (The inclusion of a log message is optional for successes.) Messages recorded with `log()` will appear in a report's results but are not associated with a particular object or status.
+
+To perform additional tasks, such as sending an email or calling a webhook, after a report has been run, extend the `post_run()` method. The status of the report is available as `self.failed` and the results object is `self.result`.
+
+Once you have created a report, it will appear in the reports list. Initially, reports will have no results associated with them. To generate results, run the report.
+
+## Running Reports
+
+### Via the Web UI
+
+Reports can be run via the web UI by navigating to the report and clicking the "run report" button at top right. Note that a user must have permission to create ReportResults in order to run reports. (Permissions can be assigned through the admin UI.)
+
+Once a report has been run, its associated results will be included in the report view.
+
+### Via the API
+
+To run a report via the API, simply issue a POST request to its `run` endpoint. Reports are identified by their module and class name.
+
+```
+    POST /api/extras/reports/<module>.<name>/run/
+```
+
+Our example report above would be called as:
+
+```
+    POST /api/extras/reports/devices.DeviceConnectionsReport/run/
+```
+
+### Via the CLI
+
+Reports can be run on the CLI by invoking the management command:
+
+```
+python3 manage.py runreport <module>
+```
+
+One or more report modules may be specified.
