That can't work. I guess what you're trying to do can be accomplished with ImageGroup.objects.select_related().latest(). Or any other filter you require, instead of the latest() shortcut. See how to read out the list of related fields in the django docs, and also not that you can do filter() on fields of the related models as well, for example Image.objsects.filter(imagegroup__new__islive=True). Also - "News" has no singular form,"New" is a weird class name to use, isn't it ? :) > I read the docs and found examples in this group but I can't get my > head around it how it works on my model layout. > > any help will be greatly appreciated. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Django users" group.
