我是Django的新手，这是我第一次使用该框架创建Web应用程序。我的Web应用程序有3种用户类型：客户，主管和承包商。这三个用户通过称为“用户”的OneToOneField连接到自定义用户模型。 （我的自定义用户模型子类AbstractAbstractUser） 我已经创建了数据库表并运行迁移，完成了所有初始的工作，等等，但是当我尝试为我的Web应用程序创建Client用户（该子类将models.Model子类化）时，出现以下AttributeError：'Client对象没有属性“ set_password”。
我看过一些解决方案，它们建议定义自己的set_password属性（因为models.Model没有这样的属性），或者子类化AbstractBaseUser。我想尝试第一种方法，但是，对于如何为模型定义'set_password'属性，我有些困惑。 附注：请随时指出我的代码中的其他任何错误。
