python - 类型错误 : Field 'id' expected a number but got (()

Question

你好，我需要你的帮助:)

我在学校参与这个 Django 元素。我用 AbstractBaseUser 类替换了 auth_user 表，并创建了一个名为 UserLogin 的新类。所以创建一个 super 用户工作正常，但创建用户注册页面不工作

我现在花了大约 10 个小时来解决这个错误。希望你能帮助我谢谢你

如果你需要更多信息，请写下来

这是整个错误信息

TypeError: Field 'id' expected a number but got ((), {'email': 'admin@adminator.ch', 'first_name': 'ksfd', 'last_name': 'dfsg', 'location': 'Bern', 'date_of_birth': datetime.datetime(2020, 9, 29, 0, 0, tzinfo=<UTC>), 'plz': 4589, 'license_plate_number': 80291, 'license_plate_char': 'BE', 'country': 'CH', 'address': 'adminstrasse', 'phone_number': '0453268', 'raw_password': 'Balmistar45!', 'is_staff': False, 'is_superuser': False}).

所以我只想写下问题的解决方案。或者只是对我有帮助的事情。

正如@Charles 所说，这只是一个迁移错误，我的元素也有问题。当我的 friend 克隆 repo 并试用它时，代码完美运行。

所以我刚刚删除了计算机上的元素。创建了一个新元素并将其从我的 GitHub 存储库中合并下来，它成功了。

所以我希望我能在这方面帮助别人。
