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

最佳答案
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。
