## Built-in OpenAPI schema support
|
|
|
|
REST framework now has a first-pass at directly including OpenAPI schema support. (Formerly known as Swagger)
|
|
|
|
Specifically:
|
|
|
|
* There are now `OpenAPIRenderer`, and `JSONOpenAPIRenderer` classes that deal with encoding `coreapi.Document` instances into OpenAPI YAML or OpenAPI JSON.
|
|
* The `get_schema_view(...)` method now defaults to OpenAPI YAML, with CoreJSON as a secondary
|
|
option if it is selected via HTTP content negotiation.
|
|
* There is a new management command `generateschema`, which you can use to dump
|
|
the schema into your repository.
|
|
|
|
Here's an example of adding an OpenAPI schema to the URL conf:
|
|
|
|
```python
|
|
from rest_framework.schemas import get_schema_view
|
|
from rest_framework.renderers import JSONOpenAPIRenderer
|
|
from django.urls import path
|
|
|
|
schema_view = get_schema_view(
|
|
title="Server Monitoring API",
|
|
url="https://www.example.org/api/",
|
|
renderer_classes=[JSONOpenAPIRenderer],
|
|
)
|
|
|
|
urlpatterns = [path("schema.json", schema_view), ...]
|
|
```
|
|
|
|
And here's how you can use the `generateschema` management command:
|
|
|
|
```shell
|
|
$ python manage.py generateschema --format openapi > schema.yml
|
|
```
|
|
|
|
There's lots of different tooling that you can use for working with OpenAPI
|
|
schemas. One option that we're working on is the [API Star](https://docs.apistar.com/)
|
|
command line tool.
|
|
|
|
You can use `apistar` to validate your API schema:
|
|
|
|
```shell
|
|
$ apistar validate --path schema.json --format openapi
|
|
✓ Valid OpenAPI schema.
|
|
```
|
|
|
|
Or to build API documentation:
|
|
|
|
```shell
|
|
$ apistar docs --path schema.json --format openapi
|
|
✓ Documentation built at "build/index.html".
|
|
```
|
|
|
|
API Star also includes a [dynamic client library](https://docs.apistar.com/client-library/)
|
|
that uses an API schema to automatically provide a client library interface for making requests.
|
|
|
|
## Composable permission classes
|
|
|
|
You can now compose permission classes using the and/or operators, `&` and `|`.
|
|
|
|
For example...
|
|
|
|
```python
|
|
permission_classes = [IsAuthenticated & (ReadOnly | IsAdminUser)]
|
|
```
|
|
|
|
If you're using custom permission classes then make sure that you are subclassing
|
|
from `BasePermission` in order to enable this support.
|
|
|
|
## ViewSet _Extra Actions_ available in the Browsable API
|
|
|
|
Following the introduction of the `action` decorator in v3.8, _extra actions_ defined on a ViewSet are now available
|
|
from the Browsable API.
|
|
|
|
|
|
|
|
When defined, a dropdown of "Extra Actions", appropriately filtered to detail/non-detail actions, is displayed.
|
|
|

|
|
|
|
## Supported Versions
|
|
|
|
REST framework 3.9 supports Django versions 1.11, 2.0, and 2.1.
|
|
|
|

|
|
|
|
## Deprecations
|
|
|
|
### `DjangoObjectPermissionsFilter` moved to third-party package.
|
|
|
|
The `DjangoObjectPermissionsFilter` class is pending deprecation, will be deprecated in 3.10 and removed entirely in 3.11.
|
|
|
|
It has been moved to the third-party [`djangorestframework-guardian`](https://github.com/rpkilby/django-rest-framework-guardian)
|
|
package. Please use this instead.
|
|
|
|
### Router argument/method renamed to use `basename` for consistency.
|
|
|
|
* The `Router.register` `base_name` argument has been renamed in favor of `basename`.
|
|
* The `Router.get_default_base_name` method has been renamed in favor of `Router.get_default_basename`. [#5990][gh5990]
|
|
|
|
See [#5990][gh5990].
|
|
|
|
[gh5990]: https://github.com/encode/django-rest-framework/pull/5990
|
|
|
|
`base_name` and `get_default_base_name()` are pending deprecation. They will be deprecated in 3.10 and removed entirely in 3.11.
|
|
|
|
### `action` decorator replaces `list_route` and `detail_route`
|
|
|
|
Both `list_route` and `detail_route` are now deprecated in favour of the single `action` decorator.
|
|
They will be removed entirely in 3.10.
|
|
|
|
The `action` decorator takes a boolean `detail` argument.
|
|
|
|
* Replace `detail_route` uses with `@action(detail=True)`.
|
|
* Replace `list_route` uses with `@action(detail=False)`.
|
|
|
|
### `exclude_from_schema`
|
|
|
|
Both `APIView.exclude_from_schema` and the `exclude_from_schema` argument to the `@api_view` have now been removed.
|
|
|
|
For `APIView` you should instead set a `schema = None` attribute on the view class.
|
|
|
|
For function-based views the `@schema` decorator can be used to exclude the view from the schema, by using `@schema(None)`.
|

## Minor fixes and improvements
|
|
|
|
There are a large number of minor fixes and improvements in this release. See the [release notes](release-notes.md) page for a complete listing.
|
|
|
|
|
|
## What's next
|
|
|
|
We're planning to iteratively work towards OpenAPI becoming the standard schema
|
|
representation. This will mean that the `coreapi` dependency will gradually become
|
|
removed, and we'll instead generate the schema directly, rather than building
|
|
a CoreAPI `Document` object.
|
|
|
|
OpenAPI has clearly become the standard for specifying Web APIs, so there's not
|
|
much value any more in our schema-agnostic document model. Making this change
|
|
will mean that we'll more easily be able to take advantage of the full set of
|
|
OpenAPI functionality.
|
|
|
|
This will also make a wider range of tooling available.
|
|
|
|
We'll focus on continuing to develop the [API Star](https://docs.apistar.com/)
|
|
library and client tool into a recommended option for generating API docs,
|
|
validating API schemas, and providing a dynamic client library.
|
|
|
|
There's also a huge amount of ongoing work on maturing the ASGI landscape,
|
|
with the possibility that some of this work will eventually [feed back into
|
|
Django](https://www.aeracode.org/2018/06/04/django-async-roadmap/).
|
|
|
|
There will be further work on the [Uvicorn](https://www.uvicorn.org/)
|
|
web server, as well as lots of functionality planned for the [Starlette](https://www.starlette.io/)
|
|
web framework, which is building a foundational set of tooling for working with
|
|
ASGI.
