Ahh, that's perfect. Is there any way I could use this with the 'object_list' generic view, or will I just have to roll my own view to get this one going? It's easy enough to do a view for it, but it *feels* like there'd be a way to pass some 'extra_context' to 'object_list', such that it can dynamically build QuerySets. Maybe if I could pass arguments to a callable in 'extra_context' Jay P. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Django users" group.
