Django + Heroku + MongoDB Atlas (Djon go) = Ошибка базы данных без исключения

0 голосов
/ 01 мая 2020

Описание проблемы в одной строке

Всякий раз, когда мое приложение django, развернутое на heroku, пытается получить доступ к моему кластеру MongoDB Atlas для отправки формы или проверки входа администратора, оно выдает что-то вроде прикрепленной ошибки.

Дополнительные сведения

Воспроизводимая ошибка при сборке heroku здесь

Я думаю, что эта ошибка связана с тем, как heroku взаимодействует с моим кластером MongoDB Atlas, так как Я могу заставить приложение успешно читать и вносить изменения в различные записи в моей базе данных при локальном запуске сборки.

Я включил traffi c со всех IP-адресов в мой кластер Atlas, удалил по умолчанию база данных Heroku Postrgre SQL из моего приложения Heroku и переменных конфигурации, а также собственный IP-адрес моей базы данных в качестве переменной конфигурации.

Любая помощь будет принята с благодарностью.

Как выяснилось, я забыл добавить sqlparse в мои require.txt и, следовательно, heroku не смог запустить разбор Djon go из SQL в SQL. Исходя из этой проблемы кажется, что версия 0.2.4 является наиболее стабильной версией для использования.
