Ошибка ограничения NOT NULL: profiles_tweet.author_id

Я хочу сохранить твит с ожидающим состоянием, но это дает ошибку целостности.

И еще я хочу просмотреть все твиты автора, но я не могу их отфильтровать.

Я хочу, чтобы если какой-либо твит автора что-то хранился как ожидающий в базе данных. и я хочу его просмотреть в своем профиле.
