        # If we are in a raw save, save the object exactly as presented.
        # That means that we don't try to be smart about saving attributes
        # that might have come from the parent class - we just save the
        # attributes we have been given to the class we have been given.
        # We also go through this process to defer the save of proxy objects
        # to their actual underlying model.
