The more granular cache framework is used by caching the output of a single view. Django.views.decorators.cache defines an cache_page adorner that automatically caches the view response. He is very easy to use: From Django.views.decorators.cache

The coupling of views to the caching system is not ideal in several ways. For example, you might want to reuse the view function in a site that is not cached, or you might want to publish the view to someone who doesn't want to use it through the
