 # Caching
 
-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.md#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.

+    In NetBox v2.11.10 and later queryset caching is disabled by default, and must be configured.
 
 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.

+# Adding Models
+
+## 1. Define the model class
+
+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 PrimaryModel or OrganizationalModel. Remember to add the model class to the `__all__` listing for the module.
+
+Each model should define, at a minimum:
+
+* 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()`)
+* A `Meta` class specifying a deterministic ordering (if ordered by fields other than the primary ID)
+
+## 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 -n $NAME --no-header`. Always specify a short unique name when generating migrations.
+
+!!! info
+    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. 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.
+
+Every model FilterSet should define a `q` filter to support general search queries.
+
+## 7. Create the table
+
+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.
+
+## 8. 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`.
+
+## 9. Add the model to the navigation menu
+
+For NetBox releases prior to v3.0, add the relevant link(s) to the navigation menu template. For later releases, add the relevant items in `netbox/netbox/navigation_menu.py`.
+
+## 10. 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`
+
+## 11. GraphQL API components (v3.0+)
+
+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.
+
+## 12. Add tests
+
+Add tests for the following:
+
+* UI views
+* API views
+* Filter sets
+
+## 13. 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`.
