I've added a small, but useful, addition to Django Better Cache, today. The new bettercache.decorators.CachedFormMethod utility is a decorator for Django form methods, which is essentially a memoizer, but with a nice twist. This is great for forms that include DB or search index reading methods which can be expensive and you'd like to cache, but normal memoization fails when the important parameters to key on are in the form data, not the arguments to the actual method. Read about the new decorator at the docs to learn more. class FriendsLookup ( forms . Form ): username = forms . CharField ( required = True ) @CachedFormMethod ( expires = 60 * 15 ) # expire in 15 minutes def get_friends_list ( self , include_pending = False ): username = self . cleaned_data [ 'username' ] friends = Friendship . objects . filter ( from_user__username = username ) if include_pending : friends = frie
