Caching

A certain woman had a very sharp conciousness but almost no memory ... She remembered enough to work, and she worked hard.

• Lydia Davis

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

Using cache with apiview and viewsets

Django provides a method_decorator to use decorators with class based views. This can be used with with other cache decorators such as cache_page and vary_on_cookie.

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 decorator only caches the GET and HEAD responses with status 200.
