How to cache Django Rest Framework API calls?

Question

I'm using Memcached as backend to my django app. This code works fine in normal django query:

def get_myobj():         cache_key = 'mykey'         result = cache.get(cache_key, None)         if not result:             result = Product.objects.all().filter(draft=False)             cache.set(cache_key, result)         return result 

But it doesn't work when used with django-rest-framework api calls:

class ProductListAPIView(generics.ListAPIView):     def get_queryset(self):         product_list = Product.objects.all()         return product_list     serializer_class = ProductSerializer 

I'm about to try DRF-extensions which provide caching functionality:

https://github.com/chibisov/drf-extensions

but the build status on github is currently saying "build failing".

My app is very read-heavy on api calls. Is there a way to cache these calls?

Thank you.

Ok, so, in order to use caching for your queryset:

class ProductListAPIView(generics.ListAPIView):     def get_queryset(self):         return get_myobj()     serializer_class = ProductSerializer 

You'd probably want to set a timeout on the cache set though (like 60 seconds):

cache.set(cache_key, result, 60) 

If you want to cache the whole view:

from django.utils.decorators import method_decorator from django.views.decorators.cache import cache_page  class ProductListAPIView(generics.ListAPIView):     serializer_class = ProductSerializer      @method_decorator(cache_page(60))     def dispatch(self, *args, **kwargs):         return super(ProductListAPIView, self).dispatch(*args, **kwargs)
