Caching

A certain woman had a very sharp consciousness but almost nomemory … She remembered enough to work, and she worked hard.- Lydia Davis

Caching in REST Framework works well with the cache utilitiesprovided in Django.

Using cache with apiview and viewsets

Django provides a method_decorator to usedecorators with class based views. This can be used withother cache decorators such as cache_page andvary_on_cookie.

from django.utils.decorators import method_decorator
from django.views.decorators.cache import cache_page
from django.views.decorators.vary import 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 theGET and HEAD responses with status 200.
