How to access django proxy model method?

Question

Django

There is a user model:

class User(AbstractBaseUser, PermissionsMixin):

    class Type(models.TextChoices):
        default = 'default', 'Стандартный Пользователь'
        vip = 'vip', 'Вип пользователь'


    email = models.EmailField(_('email address'), unique=True)
    phone = models.CharField(
        verbose_name='Телефон', blank=False, default='', max_length=18)
    is_active = models.BooleanField(default=True)
    date_joined = models.DateTimeField(default=timezone.now)

    type_user = models.CharField(
        'Тип', choices=Type.choices, default=Type.default, max_length=15)

And 2 proxy models:

class DefaultUser(User):

    objects = DefaultUserManager()

    def test(self):
        return 1

    class Meta:
        proxy = True

class VipUser(User):

    objects = VipUserManager()

    def test(self):
        return 2

    class Meta:
        proxy = True

Question: how can I get the result of user.test () in the template, depending on the type of the current user, without additional type checks?

Answer 1

Anton , you cannot get an inheriting class from an inherited one. You can access the test method only from instances of the DefaultUser or VipUser class on a non-User
PS
Where have you seen someone do this?

class User(AbstractBaseUser, PermissionsMixin):

    class Type(models.TextChoices):
        default = 'default', 'Стандартный Пользователь'
        vip = 'vip', 'Вип пользователь'
