Это код, который у меня есть в моем models.py. Я пытаюсь разработать небольшой сайт, используя только администратора Django.

Это проект, над которым я работаю уже довольно давно. У меня нет большого опыта в Django / Python ..
1) Связанный ключ базы данных isssue
Как извлечь идентификатор электронной почты пользователей и сделать его автозаполненным, когда пользователь сайта администратора выбирает Имя пользователя, используя раскрывающийся список?
2) Идеи разработки альтернативной базы данных
Каков наилучший способ оптимизации списка пользователей? Есть ли другой способ, как вы, ребята, могли бы предложить мне (нубу) сделать сайт таким образом, чтобы можно было добавлять дополнительных пользователей, не ограничивая сайт размещением только 3 дополнительных пользователей?
3) related_name Выпуск
Почему я получаю следующую ошибку при использовании related_name=? Как мне это исправить?

Пожалуйста, имейте в виду, что я все еще новичок и не очень разбираюсь в предмете. Возможно, вам придется немного более наглядно объяснить, что вы имеете в виду.
Большое вам спасибо!
