在 Django 中访问超类方法

Question

我有以下模型，一个用户class User(AbstractBaseUser, PermissionsMixin, Base):    email = models.EmailField(db_index=True, unique=True, max_length=255)    mobile = PhoneNumberField(null=True)    username = models.CharField(db_index=True, null=False, unique=True, max_length=255)一个基类class Room(Base):    name = models.CharField(db_index=True, unique=True, max_length=255)    status = models.CharField(default=RoomStatus.ACTIVE, max_length=256, null=True)    members = models.ManyToManyField(User)    last_activity = models.DateTimeField(default=timezone.now)还有两个孩子class LeagueRoom(Room):    league = models.ForeignKey(League, on_delete=models.CASCADE, null=True)    location = models.ForeignKey(Location, on_delete=models.CASCADE, null=True)class ClubRoom(Room):    club = models.ForeignKey(Club, on_delete=models.CASCADE, null=True)    location = models.ForeignKey(Location, on_delete=models.CASCADE, null=True)我想leagueroom_set为用户访问。我不知道该怎么做。用户当前有一个属性room_set，但我希望访问特定的 room_set。有人可以帮我弄这个吗？

Answer 1

你可以从另一端开始：

league_rooms = LeagueRoom.objects.filter(members=my_user)
