## Built-in API documentation
|
|
|
|
The built-in API documentation includes:
|
|
|
|
* Documentation of API endpoints.
|
|
* Automatically generated code samples for each of the available API client libraries.
|
|
* Support for API interaction.
|
|
|
|
### Installation
|
|
|
|
The `coreapi` library is required as a dependency for the API docs. Make sure
|
|
to install the latest version. The `Pygments` and `Markdown` libraries
|
|
are optional but recommended.
|
|
|
|
To install the API documentation, you'll need to include it in your project's URLconf:
|
|
|
|
from rest_framework.documentation import include_docs_urls
|
|
|
|
urlpatterns = [
|
|
...
|
|
path('docs/', include_docs_urls(title='My API title'))
|
|
]
|
|
|
|
This will include two different views:
|
|
|
|
* `/docs/` - The documentation page itself.
|
|
* `/docs/schema.js` - A JavaScript resource that exposes the API schema.
|
|
|
|
---
|
|
|
|
**Note**: By default `include_docs_urls` configures the underlying `SchemaView` to generate _public_ schemas.
|
|
This means that views will not be instantiated with a `request` instance. i.e. Inside the view `self.request` will be `None`.
|
|
|
|
To be compatible with this behaviour, methods (such as `get_serializer` or `get_serializer_class` etc.) which inspect `self.request` or, particularly, `self.request.user` may need to be adjusted to handle this case.
|
|
|
|
You may ensure views are given a `request` instance by calling `include_docs_urls` with `public=False`:
|
|
|
|
from rest_framework.documentation import include_docs_urls
|
|
|
|
urlpatterns = [
|
|
...
|
|
# Generate schema with valid `request` instance:
|
|
path('docs/', include_docs_urls(title='My API title', public=False))
|
|
]
|
|
|
|
|
|
---
|
|
|
|
|
|
### Documenting your views
|
|
|
|
You can document your views by including docstrings that describe each of the available actions.
|
|
For example:
|
|
|
|
class UserList(generics.ListAPIView):
|
|
"""
|
|
Return a list of all the existing users.
|
|
"""
|
|
|
|
If a view supports multiple methods, you should split your documentation using `method:` style delimiters.
|
|
|
|
class UserList(generics.ListCreateAPIView):
|
|
"""
|
|
get:
|
|
Return a list of all the existing users.
|
|
|
|
post:
|
|
Create a new user instance.
|
|
"""
|
|
|
|
When using viewsets, you should use the relevant action names as delimiters.
|
|
|
|
class UserViewSet(viewsets.ModelViewSet):
|
|
"""
|
|
retrieve:
|
|
Return the given user.
|
|
|
|
list:
|
|
Return a list of all the existing users.
|
|
|
|
create:
|
|
Create a new user instance.
|
|
"""
|
|
|
|
Custom actions on viewsets can also be documented in a similar way using the method names
|
|
as delimiters or by attaching the documentation to action mapping methods.
|
|
|
|
class UserViewSet(viewsets.ModelViewset):
|
|
...
|
|
|
|
@action(detail=False, methods=['get', 'post'])
|
|
def some_action(self, request, *args, **kwargs):
|
|
"""
|
|
get:
|
|
A description of the get method on the custom action.
|
|
|
|
post:
|
|
A description of the post method on the custom action.
|
|
"""
|
|
|
|
@some_action.mapping.put
|
|
def put_some_action():
|
|
"""
|
|
A description of the put method on the custom action.
|
|
"""
|
|
|
|
|
|
### `documentation` API Reference
|
|
|
|
The `rest_framework.documentation` module provides three helper functions to help configure the interactive API documentation, `include_docs_urls` (usage shown above), `get_docs_view` and `get_schemajs_view`.
|
|
|
|
`include_docs_urls` employs `get_docs_view` and `get_schemajs_view` to generate the url patterns for the documentation page and JavaScript resource that exposes the API schema respectively. They expose the following options for customisation. (`get_docs_view` and `get_schemajs_view` ultimately call `rest_frameworks.schemas.get_schema_view()`, see the Schemas docs for more options there.)
|
|
|
|
#### `include_docs_urls`
|
|
|
|
* `title`: Default `None`. May be used to provide a descriptive title for the schema definition.
|
|
* `description`: Default `None`. May be used to provide a description for the schema definition.
|
|
* `schema_url`: Default `None`. May be used to pass a canonical base URL for the schema.
|
|
* `public`: Default `True`. Should the schema be considered _public_? If `True` schema is generated without a `request` instance being passed to views.
|
|
* `patterns`: Default `None`. A list of URLs to inspect when generating the schema. If `None` project's URL conf will be used.
|
|
* `generator_class`: Default `rest_framework.schemas.SchemaGenerator`. May be used to specify a `SchemaGenerator` subclass to be passed to the `SchemaView`.
|
|
* `authentication_classes`: Default `api_settings.DEFAULT_AUTHENTICATION_CLASSES`. May be used to pass custom authentication classes to the `SchemaView`.
|
|
* `permission_classes`: Default `api_settings.DEFAULT_PERMISSION_CLASSES` May be used to pass custom permission classes to the `SchemaView`.
|
|
* `renderer_classes`: Default `None`. May be used to pass custom renderer classes to the `SchemaView`.
|
|
|
|
#### `get_docs_view`
|
|
|
|
* `title`: Default `None`. May be used to provide a descriptive title for the schema definition.
|
|
* `description`: Default `None`. May be used to provide a description for the schema definition.
|
|
* `schema_url`: Default `None`. May be used to pass a canonical base URL for the schema.
|
|
* `public`: Default `True`. If `True` schema is generated without a `request` instance being passed to views.
|
|
* `patterns`: Default `None`. A list of URLs to inspect when generating the schema. If `None` project's URL conf will be used.
|
|
* `generator_class`: Default `rest_framework.schemas.SchemaGenerator`. May be used to specify a `SchemaGenerator` subclass to be passed to the `SchemaView`.
|
|
* `authentication_classes`: Default `api_settings.DEFAULT_AUTHENTICATION_CLASSES`. May be used to pass custom authentication classes to the `SchemaView`.
|
|
* `permission_classes`: Default `api_settings.DEFAULT_PERMISSION_CLASSES`. May be used to pass custom permission classes to the `SchemaView`.
|
|
* `renderer_classes`: Default `None`. May be used to pass custom renderer classes to the `SchemaView`. If `None` the `SchemaView` will be configured with `DocumentationRenderer` and `CoreJSONRenderer` renderers, corresponding to the (default) `html` and `corejson` formats.
|
|
|
|
#### `get_schemajs_view`
|
|
|
|
* `title`: Default `None`. May be used to provide a descriptive title for the schema definition.
|
|
* `description`: Default `None`. May be used to provide a description for the schema definition.
|
|
* `schema_url`: Default `None`. May be used to pass a canonical base URL for the schema.
|
|
* `public`: Default `True`. If `True` schema is generated without a `request` instance being passed to views.
|
|
* `patterns`: Default `None`. A list of URLs to inspect when generating the schema. If `None` project's URL conf will be used.
|
|
* `generator_class`: Default `rest_framework.schemas.SchemaGenerator`. May be used to specify a `SchemaGenerator` subclass to be passed to the `SchemaView`.
|
|
* `authentication_classes`: Default `api_settings.DEFAULT_AUTHENTICATION_CLASSES`. May be used to pass custom authentication classes to the `SchemaView`.
|
|
* `permission_classes`: Default `api_settings.DEFAULT_PERMISSION_CLASSES` May be used to pass custom permission classes to the `SchemaView`.

### Customising code samples
|
|
|
|
The built-in API documentation includes automatically generated code samples for
|
|
each of the available API client libraries.
|
|
|
|
You may customise these samples by subclassing `DocumentationRenderer`, setting
|
|
`languages` to the list of languages you wish to support:
|
|
|
|
from rest_framework.renderers import DocumentationRenderer
|
|
|
|
|
|
class CustomRenderer(DocumentationRenderer):
|
|
languages = ['ruby', 'go']
|
|
|
|
For each language you need to provide an `intro` template, detailing installation instructions and such,
|
|
plus a generic template for making API requests, that can be filled with individual request details.
|
|
See the [templates for the bundled languages][client-library-templates] for examples.
