Good grief. After spending hours trying to figure out what was wrong, I immediately found the problem after making this post. Here's the solution:
I had overridden UserProfile.__init__() like this: class UserProfile(models.Model): def __init__(self, website='http://www.default.com'): while its superclass looks like this: class Model(object): ... def __init__(self, *args, **kwargs): Somewhere deep inside Django the 'model.__init__()' was being called to create a UserProfile passing it a bunch of parameters it was not prepared to accept. So I just changed it to: class UserProfile(models.Model): def __init__(self, website='http://www.default.com', *args, **kwargs): ... and all was well. That explained the 'TypeError: __init__() takes at most 2 arguments (4 given) ' message. -- You received this message because you are subscribed to the Google Groups "Django users" group.
