Я собираю CRM, и у меня небольшие проблемы. Все работало просто отлично, пока я не попытался провести время с DateTimeField с SQLAlchemy. Перед добавлением поля времени запись будет создаваться и добавляться в базу данных без каких-либо проблем. Однако после этого я просто не смогу создать запись. Страница перезагрузится, и у меня не будет ошибок проверки. Я подключился к этому, и наконец получил ошибку. Все данные проходят нормально, кроме времени. Время подается как <wtforms.fields.core.DateTimeField object at 0x10fe67210>. Как мне обойти эту проблему? Я чувствую, что решение простое, и я буду чувствовать себя глупым, если не увижу его раньше. Ваша помощь очень ценится!
Вот весь журнал ошибок:
sqlalchemy.exc.StatementError
