# Django REST framework 3.12
|
||||
|
||||
REST framework 3.12 brings a handful of refinements to the OpenAPI schema
|
||||
generation, plus support for Django's new database-agnostic `JSONField`,
|
||||
and some improvements to the `SearchFilter` class.
|
||||
|
||||
## Grouping operations with tags.
|
||||
|
||||
Open API schemas will now automatically include tags, based on the first element
|
||||
in the URL path.
|
||||
|
||||
For example...
|
||||
|
||||
Method | Path | Tags
|
||||
--------------------------------|-----------------|-------------
|
||||
`GET`, `PUT`, `PATCH`, `DELETE` | `/users/{id}/` | `['users']`
|
||||
`GET`, `POST` | `/users/` | `['users']`
|
||||
`GET`, `PUT`, `PATCH`, `DELETE` | `/orders/{id}/` | `['orders']`
|
||||
`GET`, `POST` | `/orders/` | `['orders']`
|
||||
|
||||
The tags used for a particular view may also be overridden...
|
||||
|
||||
```python
|
||||
class MyOrders(APIView):
|
||||
schema = AutoSchema(tags=['users', 'orders'])
|
||||
...
|
||||
```
|
||||
|
||||
See [the schema documentation](https://www.django-rest-framework.org/api-guide/schemas/#grouping-operations-with-tags) for more information.
|
||||
|
||||
## Customizing the operation ID.
|
||||
|
||||
REST framework automatically determines operation IDs to use in OpenAPI
|
||||
schemas. The latest version provides more control for overriding the behaviour
|
||||
used to generate the operation IDs.
|
||||
|
||||
See [the schema documentation](https://www.django-rest-framework.org/api-guide/schemas/#operationid) for more information.
|
||||
|
||||
## Support for OpenAPI components.
|
||||
|
||||
In order to output more graceful OpenAPI schemes, REST framework 3.12 now
|
||||
defines components in the schema, and then references them inside request
|
||||
and response objects. This is in contrast with the previous approach, which
|
||||
fully expanded the request and response bodies for each operation.
|
||||
|
||||
The names used for a component default to using the serializer class name, [but
|
||||
may be overridden if needed](https://www.django-rest-framework.org/api-guide/schemas/#components
|
||||
)...
|
||||
|
||||
```python
|
||||
class MyOrders(APIView):
|
||||
schema = AutoSchema(component_name="OrderDetails")
|
||||
```
|
||||
|
||||
## More Public API
|
||||
|
||||
Many methods on the `AutoSchema` class have now been promoted to public API,
|
||||
allowing you to more fully customize the schema generation. The following methods
|
||||
are now available for overriding...
|
||||
|
||||
* `get_path_parameters`
|
||||
* `get_pagination_parameters`
|
||||
* `get_filter_parameters`
|
||||
* `get_request_body`
|
||||
* `get_responses`
|
||||
* `get_serializer`
|
||||
* `get_paginator`
|
||||
* `map_serializer`
|
||||
* `map_field`
|
||||
* `map_choice_field`
|
||||
* `map_field_validators`
|
||||
* `allows_filters`.
|
||||
|
||||
See [the schema docs](https://www.django-rest-framework.org/api-guide/schemas/#per-view-customization)
|
||||
for details on using custom `AutoSchema` subclasses.
|
||||
|
||||
## Support for JSONField.
|
||||
|
||||
Django 3.1 deprecated the existing `django.contrib.postgres.fields.JSONField`
|
||||
in favour of a new database-agnositic `JSONField`.
|
||||
|
||||
REST framework 3.12 now supports this new model field, and `ModelSerializer`
|
||||
classes will correctly map the model field.
|
||||
|
||||
## SearchFilter improvements
|
||||
|
||||
There are a couple of significant improvements to the `SearchFilter` class.
|
||||
|
||||
### Nested searches against JSONField and HStoreField
|
||||
|
||||
The class now supports nested search within `JSONField` and `HStoreField`, using
|
||||
the double underscore notation for traversing which element of the field the
|
||||
search should apply to.
|
||||
|
||||
```python
|
||||
class SitesSearchView(generics.ListAPIView):
|
||||
"""
|
||||
An API view to return a list of archaeological sites, optionally filtered
|
||||
by a search against the site name or location. (Location searches are
|
||||
matched against the region and country names.)
|
||||
"""
|
||||
queryset = Sites.objects.all()
|
||||
serializer_class = SitesSerializer
|
||||
filter_backends = [filters.SearchFilter]
|
||||
search_fields = ['site_name', 'location__region', 'location__country']
|
||||
```
|
||||
|
||||
### Searches against annotate fields
|
||||
|
||||
Django allows querysets to create additional virtual fields, using the `.annotate`
|
||||
method. We now support searching against annotate fields.
|
||||
|
||||
```python
|
||||
class PublisherSearchView(generics.ListAPIView):
|
||||
"""
|
||||
Search for publishers, optionally filtering the search against the average
|
||||
rating of all their books.
|
||||
"""
|
||||
queryset = Publisher.objects.annotate(avg_rating=Avg('book__rating'))
|
||||
serializer_class = PublisherSerializer
|
||||
filter_backends = [filters.SearchFilter]
|
||||
search_fields = ['avg_rating']
|
||||
```
|
||||
