I have sat and thought about this for a while and I still have absolutely no idea what you're asking. Could you forget about the abstract stuff with animals and cages and show some small examples of the code you're trying to write and an explanation of what isn't working? Is an animal class meant to be linked to a cage class? Is a cage even a class, or is it an attribute? Why was serializing ever an option for relational model representation? Unfortunately, you've over-generalised your problem to the degree that it probably only makes sense to you now. :-) Regards, Malcolm --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Django users" group.
