Views

To make sure the browser doesn’t cache a view, add the never_cache decorator to the view function:

from django.views.decorators.cache import never_cache
@never_cache
def edit_article(request, title...

…this will add the following header to the HTTP response:

Cache-Control : max-age=0

Note: I haven’t tested this yet…

To control the cache on a view function:

from django.views.decorators.cache import cache_page

@cache_page(60 * 15)
def my_view(request):
    ...

… or in the URL configuration:

from django.views.decorators.cache import cache_page

urlpatterns = ('',
    (r'^foo/(\d{1,2})/$', cache_page(my_view, 60 * 15)),
)

Note:

It appears much simpler to use cache_page on the view function, but this couples the view to it’s cache behaviour. To solve this issue, set the cache settings in the URLconf.
cache_page takes a single argument: the cache timeout, in seconds.
