正如你所说的，你会得到这些错误，因为你的表没有AbstractUser模型中定义的字段的列。最简单的解决方案是将所有缺失的字段添加到你的表中。
或者，如果你想避免这种情况，你可以让你的用户模型子类AbstractBaseUser代替。这个抽象模型只有password和last_login的字段。注意，这种方法会有更多的工作。这似乎是一个很好的指南：

"I have fixed this problem after a lot of tries. Just pass AbstractBaseUser in the class CustomUser(AbstractBaseUser) and don't include PermissionsMixin in the parameters and for the extra column which are not matching include last_login = None and the CustomUser model will run as expected. 
Adding the code for reference. "
