这里我使用 AbstractBaseUser 扩展用户模型。 我想添加一个新的个人资料。 我正在使用 OneToOneField 添加带有 CustomUser 模型的配置文件模型。 我的注册和登录工作正常。 但看不到配置文件，它给出了错误 但是我正面临上述问题，请帮助我！

【问题讨论】：

分享您的模型和完整的错误回溯

错误回溯粘贴在此链接中。 pastebin.com/dUvWtxS4

这是导致行 prf = Profile.objects.get(user = request.user) 的错误，顺便说一句，我在共享代码中没有看到任何变量 prf？

我认为因为 profile 是函数的名称。也许它可能导致错误。所以将个人资料更改为 prf。

然后也更新帖子..

【参考方案1】：

解决了。

我在signals.py 中遇到Profile.objects.create 的问题 它是从apps.py 导入的。 在 settings.py 安装的应用程序中，我直接包含了我的appname。 通过写'users'。 将用户更改为'users.apps.UsersConfig' 解决了这个错误。
