«Не удается запросить Conversationt, используйте набор запросов для профиля»

Question

Я пытаюсь запросить мои Conversation объекты и получить объект convo, который может быть уже создан или не создан между двумя пользователями. Затем я хочу получить get_or_create один проход в двух пользователей. Теперь я получаю объект запроса не может. Используйте профиль "... не уверен, почему это так. Я должен возвращать список, который я могу добавить, или, если он не может его получить, он должен его создать. Conversation объект имеет поле ManyToMany с именем Members. Profile - это моя пользовательская модель, которую я создал.
