При передаче данных контроллеру ошибка:
Got AttributeError when attempting to get a value for field `questions` on serializer `SurveyCreateSerializer`.
The serializer field might be named incorrectly and not match any attribute or key on the `Survey` instance.
Original exception text was: 'Survey' object has no attribute 'questions'.
Не пойму как решить, обьясните в чем ошибка.
