The Django tutorial mentions this -- a Django QuerySet is "lazy", which means that it doesn't do a query until it absolutely has to. So, for example, simply writing "SomeModel.objects.all()" doesn't immediately execute the query -- you can tack filters and whatnot onto it, and all they'll do is refine the query that eventually gets executed. In this specific case, slicing a QuerySet (e.g., "SomeModel.objects.all()[:5]" or whatever) will just add a LIMIT clause to the query that gets executed, rather than retrieving all the objects and then plucking a few out. -- "Bureaucrat Conrad, you are technically correct -- the best kind of correct." --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Django users" group.
