Routers
Resource routing allows you to quickly declare all of the common routes for a given resourceful controller. Instead of declaring separate routes for your index... a resourceful route declares them in a single line of code.
Some Web frameworks such as Rails provide functionality for automatically determining how the URLs for an application should be mapped to the logic that deals with handling incoming requests.
REST framework adds support for automatic URL routing to Django, and provides you with a simple, quick and consistent way of wiring your view logic to a set of URLs.
Usage
Here's an example of a simple URL conf, that uses DefaultRouter
.
router = routers.SimpleRouter()
router.register(r'users', UserViewSet, 'user')
router.register(r'accounts', AccountViewSet, 'account')
urlpatterns = router.urls
There are three arguments to the register()
method:
prefix
- The URL prefix to use for this set of routes.viewset
- The viewset class.basename
- The base to use for the URL names that are created.
The example above would generate the following URL patterns:
- URL pattern:
^users/$
Name:'user-list'
- URL pattern:
^users/{pk}/$
Name:'user-detail'
- URL pattern:
^accounts/$
Name:'account-list'
- URL pattern:
^accounts/{pk}/$
Name:'account-detail'
Extra link and actions
Any @link
or @action
methods on the viewsets will also be routed.
For example, a given method like this on the UserViewSet
class:
@action(permission_classes=[IsAdminOrIsSelf])
def set_password(self, request, pk=None):
...
The following URL pattern would additionally be generated:
- URL pattern:
^users/{pk}/set_password/$
Name:'user-set-password'
API Guide
SimpleRouter
This router includes routes for the standard set of list
, create
, retrieve
, update
, partial_update
and destroy
actions. The viewset can also mark additional methods to be routed, using the @link
or @action
decorators.
URL Style | HTTP Method | Action | URL Name |
---|---|---|---|
{prefix}/ | GET | list | {basename}-list |
POST | create | ||
{prefix}/{lookup}/ | GET | retrieve | {basename}-detail |
PUT | update | ||
PATCH | partial_update | ||
DELETE | destroy | ||
{prefix}/{lookup}/{methodname}/ | GET | @link decorated method | {basename}-{methodname} |
POST | @action decorated method |
DefaultRouter
This router is similar to SimpleRouter
as above, but additionally includes a default API root view, that returns a response containing hyperlinks to all the list views. It also generates routes for optional .json
style format suffixes.
URL Style | HTTP Method | Action | URL Name |
---|---|---|---|
[.format] | GET | automatically generated root view | api-root |
{prefix}/[.format] | GET | list | {basename}-list |
POST | create | ||
{prefix}/{lookup}/[.format] | GET | retrieve | {basename}-detail |
PUT | update | ||
PATCH | partial_update | ||
DELETE | destroy | ||
{prefix}/{lookup}/{methodname}/[.format] | GET | @link decorated method | {basename}-{methodname} |
POST | @action decorated method |
