Caching in REST Framework works well with the cache utilities
|
|
provided in Django.
|

|
## Using cache with apiview and viewsets
|
|
|
|
Django provides a [`method_decorator`][decorator] to use
|
|
decorators with class based views. This can be used with
|
|
with other cache decorators such as [`cache_page`][page] and
|
|
[`vary_on_cookie`][cookie].
|
|
|
|
```python
|
|
from rest_framework.response import Response
|
|
from rest_framework.views import APIView
|
|
from rest_framework import viewsets
|
|
|
|
class UserViewSet(viewsets.Viewset):
|
|
|
|
# Cache requested url for each user for 2 hours
|
|
@method_decorator(cache_page(60*60*2))
|
|
@method_decorator(vary_on_cookie)
|
|
def list(self, request, format=None):
|
|
content = {
|
|
'user_feed': request.user.get_user_feed()
|
|
}
|
|
return Response(content)
|
|
|
|
class PostView(APIView):
|
|
|
|
# Cache page for the requested url
|
|
@method_decorator(cache_page(60*60*2))
|
|
def get(self, request, format=None):
|
|
content = {
|
|
'title': 'Post title',
|
|
'body': 'Post content'
|
|
}
|
|
return Response(content)
|
|
```
|
|
|
|
**NOTE:** The [`cache_page`][page] decorator only caches the
|
|
`GET` and `HEAD` responses with status 200.
