Django中MyPy检测遇UserManager类型不兼容等错误，求解决方案

运行MyPy时出现以下错误：

error: Cannot override class variable (previously declared on base class "User") with instance variable  [misc]
error: Incompatible types in assignment (expression has type "type[BuyerManager[Any]]", base class "User" defined the type as "UserManager[User]")  [assignment]

我的代码如下：

class User(AbstractUser):
    ...


class Buyer(User):
    objects = BuyerManager()


class BuyerManager(UserManager):
    def get_queryset(self) -> QuerySet:
        return super().get_queryset().filter(status="buyer")

目前尝试过两种处理方式：

• 给objects赋值添加# type: ignore忽略类型检查：objects = BuyerManager() # type: ignore
• 考虑不重写get_queryset，而是新增buyers过滤方法在需要时调用

想了解是否有更优的解决方案，欢迎分享建议。
