### Extra link and actions
Any methods on the viewset decorated with `@link` or `@action` will also be routed.
Any methods on the viewset decorated with `@detail_route` or `@list_route` will also be routed.
For example, given a method like this on the `UserViewSet` class:
from myapp.permissions import IsAdminOrIsSelf
from rest_framework.decorators import action
@action(permission_classes=[IsAdminOrIsSelf])
def set_password(self, request, pk=None):
from myapp.permissions import IsAdminOrIsSelf
from rest_framework.decorators import detail_route
class UserViewSet(ModelViewSet):
...
@detail_route(methods=['post'], 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'`
For more information see the viewset documentation on [marking extra actions for routing][route-decorators].
# 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.

Trailing slashes are conventional in Django, but are not used by default in some other frameworks such as Rails. Which style you choose to use is largely a matter of preference, although some javascript frameworks may expect a particular routing style.
The router will match lookup values containing any characters except slashes and period characters. For a more restrictive (or lenient) lookup pattern, set the `lookup_value_regex` attribute on the viewset. For example, you can limit the lookup to valid UUIDs:
class MyModelViewSet(mixins.RetrieveModelMixin, viewsets.GenericViewSet):
lookup_field = 'my_model_id'
lookup_value_regex = '[0-9a-f]{32}'
## DefaultRouter

**initkwargs**: A dictionary of any additional arguments that should be passed when instantiating the view. Note that the `suffix` argument is reserved for identifying the viewset type, used when generating the view name and breadcrumb links.
## Customizing dynamic routes
You can also customize how the `@list_route` and `@detail_route` decorators are routed.
To route either or both of these decorators, include a `DynamicListRoute` and/or `DynamicDetailRoute` named tuple in the `.routes` list.
The arguments to `DynamicListRoute` and `DynamicDetailRoute` are:
**url**: A string representing the URL to be routed. May include the same format strings as `Route`, and additionally accepts the `{methodname}` and `{methodnamehyphen}` format strings.
**name**: The name of the URL as used in `reverse` calls. May include the following format strings: `{basename}`, `{methodname}` and `{methodnamehyphen}`.
**initkwargs**: A dictionary of any additional arguments that should be passed when instantiating the view.
## Example
The following example will only route to the `list` and `retrieve` actions, and does not use the trailing slash convention.
from rest_framework.routers import Route, SimpleRouter
from rest_framework.routers import Route, DynamicDetailRoute, SimpleRouter
class ReadOnlyRouter(SimpleRouter):
class CustomReadOnlyRouter(SimpleRouter):
"""
A router for read-only APIs, which doesn't use trailing slashes.
"""
routes = [
Route(url=r'^{prefix}$',
mapping={'get': 'list'},
name='{basename}-list',
initkwargs={'suffix': 'List'}),
Route(url=r'^{prefix}/{lookup}$',
mapping={'get': 'retrieve'},
name='{basename}-detail',
initkwargs={'suffix': 'Detail'})
Route(
url=r'^{prefix}$',
mapping={'get': 'list'},
name='{basename}-list',
initkwargs={'suffix': 'List'}
),
Route(
url=r'^{prefix}/{lookup}$',
mapping={'get': 'retrieve'},
name='{basename}-detail',
initkwargs={'suffix': 'Detail'}
),
DynamicDetailRoute(
url=r'^{prefix}/{lookup}/{methodnamehyphen}$',
name='{basename}-{methodnamehyphen}',
initkwargs={}
)
]
The `SimpleRouter` class provides another example of setting the `.routes` attribute.
Let's take a look at the routes our `CustomReadOnlyRouter` would generate for a simple viewset.
`views.py`:
class UserViewSet(viewsets.ReadOnlyModelViewSet):
"""
A viewset that provides the standard actions
"""
queryset = User.objects.all()
serializer_class = UserSerializer
lookup_field = 'username'
@detail_route()
def group_names(self, request):
"""
Returns a list of all the group names that the given
user belongs to.
"""
user = self.get_object()
groups = user.groups.all()
return Response([group.name for group in groups])
`urls.py`:
router = CustomReadOnlyRouter()
router.register('users', UserViewSet)
urlpatterns = router.urls
The following mappings would be generated...
<table border=1>
<tr><th>URL</th><th>HTTP Method</th><th>Action</th><th>URL Name</th></tr>
<tr><td>/users</td><td>GET</td><td>list</td><td>user-list</td></tr>
<tr><td>/users/{username}</td><td>GET</td><td>retrieve</td><td>user-detail</td></tr>
<tr><td>/users/{username}/group-names</td><td>GET</td><td>group_names</td><td>user-group-names</td></tr>
</table>

## How clients are identified
The `X-Forwarded-For` and `Remote-Addr` HTTP headers are used to uniquely identify client IP addresses for throttling. If the `X-Forwarded-For` header is present then it will be used, otherwise the value of the `Remote-Addr` header will be used.
If you need to strictly identify unique client IP addresses, you'll need to first configure the number of application proxies that the API runs behind by setting the `NUM_PROXIES` setting. This setting should be an integer of zero or more. If set to non-zero then the client IP will be identified as being the last IP address in the `X-Forwarded-For` header, once any application proxy IP addresses have first been excluded. If set to zero, then the `Remote-Addr` header will always be used as the identifying IP address.
It is important to understand that if you configure the `NUM_PROXIES` setting, then all clients behind a unique [NAT'd](http://en.wikipedia.org/wiki/Network_address_translation) gateway will be treated as a single client.
Further context on how the `X-Forwarded-For` header works, and identifing a remote client IP can be [found here][identifing-clients].
## Setting up the cache
The throttle classes provided by REST framework use Django's cache backend. You should make sure that you've set appropriate [cache settings][cache-setting]. The default value of `LocMemCache` backend should be okay for simple setups. See Django's [cache documentation][cache-docs] for more details.
