Неизвестное поле(а) (groups, user_permissions, date_joined, is_superuser), указанное для Account

Я просто попробовал добавить "is_saler = models.BooleanField(default=False)" в класс Account и мигрировать. И теперь я получил ошибку при попытке изменить данные суперпользователя. Строка "is_saler = models.BooleanField(default=False)" была удалена, но после миграции я все равно получил эту ошибку.

    def create_user(self, first_name, last_name, username, email, password=None):
        if not email:
            raise ValueError('User must have an email address')

            first_name = first_name,
            last_name = last_name,
        )
