我正试图从已经从AbstractBaseUser继承的User类进行继承，但我收到一个错误，告诉我AUTH_User_MODEL指的是模型的身份验证。尚未安装的用户"，并且我确信我添加了AUTH_User_MODEL="身份验证"。User'在settings.py中，我想知道我如何才能克服这个错误并成功地从User类中固有这是代码：

我认为问题在于将自定义用户模型作为抽象模型。
请重新检查、核实和确认。
对于以后会遇到这种情况的人，我已经通过使用代理模型而不是使用抽象类解决了这个问题，您也可以从User类中创建一个一对一字段，并将其用于其他类，或者您可以简单地在User模型中创建角色属性，而不是为其创建其他模型，并跟踪您创建的每个视图中的角色。
