Я развернул свое приложение Django на сервере DigitalOcean через nginx, gunicorn. Сегодня я хотел добавить скрипт models.DateTimeField(auto_now_add=True) для сохранения даты отправки сообщения от пользователя, но во время миграции (после извлечения всего хранилища из github на сервере ubuntu) я получаю следующую ошибку. И я предполагаю, что проблема в файлах миграции, но я не знаю, как я могу манипулировать ими на сервере и как сделать это безопасно, без потери каких-либо данных.
Ошибка:
