It would help others to define a few terms here before leaping into the acronyms: ABC = "abstract base class", MTI = "multi-table inheritance", I'm guessing. > > I first tired it with MTI and set Entry.objects.all() as the queryset > attribute.

Yes, by adding a field called "child_type" or something similar and noting the content type of the most derived child, for example. > Then I tried ABC with the same models.

They different types aren't related to each other. You need to make "N" querysets and write your own version of the generic view (remember, generic views are just an aid -- they don't fit all requirements and not using them is always an option). > This seems like a fairly common use-case, Which is why it's been answered a number of times in the past. :-) Malcolm --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Django users" group.
