As others have recommended, just use the extra() method. It's not so bad :) If you really really want to avoid that, you could add a count integer field to your Blog model and maintain its value from overridden methods Article.save() and Article.delete(). So Blog.count would get refreshed every time you add/update/delete articles and your desired query becomes a straight lookup on Blog. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Django users" group.
