You get back the MyPerson object because that's the model you've specified as the profile class. Django's model inheritance does *not* automatically descend to the most derived child class instance. There are a number of good reasons for that, all covered in other threads on both this list and django-developers. You can still descend to the child classes, since they're linked via one-to-one fields, so it's a reverse relation access. Or you could include a type field in the MyPerson model that indicates the type of the child model, so that you know immediately which type of model it is.
