The per-view cache

A more granular way to use the caching framework is by caching the output of individual views. django.views.decorators.cache defines a cache_page decorator that will automatically cache the view's response for you. It's easy to use:

from django.views.decorators.cache import cache_page 
 
@cache_page(60 * 15) 
def my_view(request): 
    ...

cache_page takes a single argument: the cache timeout, in seconds. In the above example, the result of the my_view() view will be cached for 15 minutes. (Note that I've written it as 60 * 15 for the purpose of readability. 60 * 15 will be evaluated to 900-that is, 15 minutes multiplied by 60 seconds per minute.)

The per-view cache, like the per-site cache, is keyed off of the URL. If multiple URLs point at the same view, each URL will be cached separately. Continuing the my_view example, if your URLconf looks like this:

urlpatterns = [ 
    url(r'^foo/([0-9]{1,2})/$', my_view), 
]

then requests to /foo/1/ and...
