例外是：

AttributeError:无法设置属性

有人能指出哪里错了吗？

Answer 1

user = self.models(
        is_anonymous=is_anonymous,
        first_name=first_name,
        last_name=last_name,
        email=email,
        username=username,
        home_address=home_address,
        user_type=user_type,
        image_path=image_path,
        created_time=now,
        last_login=now
    )
