Well, I'm not sure if it was the intent to break this use case. Any
thoughts?
But I found a work around after talking to Rob Hudson. You can
override the syndication base class __call__ function and decorate
that. But another new thing here is you have to use the new
method_decorator [1]:
class MyFeed(Feed):
@method_decorator(cache_page(60 * 60))
def __call__(self, request, *args, **kwargs):
return super(MyFeed, self).__call__(request, *args, **kwargs)
Again, I'm not sure if this was supposed to break like this, as there
are certain advantages to do this in the URLconf, as noted in the docs
for cache_page.
