My models look fine to me.
So you're quite familiar with your models and cannot see the problem. We are not familiar with them, but only get shown the last line of the traceback. It seems like one party has a lot more information than the other here. :-) If your model is short (and preferably, try to reduce your example to a very short case that still fails), post the model. Also, look at the full traceback in the debug screen, go to the last line and click on the local variables button. You'll be able to see what "self" and "other" are. One of them *won't* be a Field class, although it should be (since creation_counter is an attribute on the Field class). That might give you some clues as to what is going wrong. Somehow you are managing to get a string into somewhere that a Field class (or subclass) is expected. Do you have a custom save() method involved here at all? It's going to be something like that, since it's not the field definitions themselves (the model validated). Sorry I can't offer an immediate solution, but the lack of information is hurting us a bit here. Regards, Malcolm -- Save the whales.
