# 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']
|
|
```
|
|
