Я работаю над бэкэндом на основе django.
У меня есть Submentor модель.Эта модель будет иметь список из имен , связанный с ней.Итак, я сделал модель под названием Список .они оба имеют отношения manytoMany .Теперь я сделал еще одну модель под названием names .Это имеет отношение ManytoMany и Список .В списке будет много имен.Каждый Субментор будет иметь один Список каждый.
После кодирования, когда я пытаюсь добавить значение в Список из консоли администратора, я получаю core.Name.none вместоимя в моем списке субменторов.
Что я делаю не так?
