django ORm автозаполнение двойного подчеркивания не работает на Pycharm

Question

Есть мои модели

class BNumberGroup(SoftDeleteModel, TimeStampedModel):
    uuid = models.UUIDField(db_index=True, default=uuid_lib.uuid4, editable=False)
    name = models.CharField(max_length=128, default="")
    user = models.ForeignKey(User, on_delete=models.CASCADE)
    operator = models.ForeignKey(Operator, on_delete=models.CASCADE)
    redirect = models.ForeignKey(Redirects, on_delete=models.CASCADE, null=True, blank=True)

    TIMEZONES = tuple(zip(pytz.all_timezones, pytz.all_timezones))
    timezone = models.CharField(max_length=32, choices=TIMEZONES, default='UTC')

    def __str__(self):
        return "-".join([self.name, str(self.operator.name), str(self.user.first_name)])


class BNumber(SoftDeleteModel):
    uuid = models.UUIDField(db_index=True, default=uuid_lib.uuid4, editable=False)
    number = models.CharField(max_length=123)
    b_number_groups = models.ForeignKey(BNumberGroup, on_delete=models.SET_NULL, null=True)

    def __str__(self):
        return str(self.number)

, когда я пишу BNumber.objects.filter(b_numbers_groups__) PyCharm не показывает другие параметры, такие как:

BNumber.objects.filter(b_numbers_groups__)
                       b_numbers_groups__uuid
                       b_numbers_groups__name
                       b_numbers_groups__user
                       b_numbers_groups__operator__id

введите описание изображения здесь

        queryset = BNumber.objects.filter(b_numbers_groups__uuid=uuid)
