Hi,
I've encountered a bug with the contenttypes framework when a model is
removed. You'll end up with a AttributeError in _add_to_cache():
'NoneType' object has no attribute '_meta'
That's because the ContentType still exists, byt ContentType.
I would like to solve it, yet I'm not sure about the recommended approach:
1. returning None for ContentType.objects.get_for_id() when the model does not
exist.
2. Raise an exception that the referenced model does not exist.
What is your idea on this?
This bug currently hits me because django-polymorphic (which I use) uses the
contenttype framework to upcast the models. As the models are removed, but the
contenttype still exists, making queries causes an AttributeError. When Django
returns a normal response, I'll see how to address this issue in django-
polymorphic too.
Best regards,
Diederik
