Функциональность обмена сообщениями в почтовых ящиках Django не работает ⇐ Python

[Anonymous]

Я пытаюсь добавить функциональность обмена сообщениями на мой веб-сайт электронной коммерции, где покупатели могут сообщать продавцам, а продавцы могут сообщать покупателям, как только покупатель что-то купит у них (еще не написал код для этого, просто хочу базовый функциональность обмена сообщениями). Вот что я пробовал. Через сообщение о сообщении_SELLER я могу напрямую сообщать об этом конкретном продавке, он приведет меня к почтовому ящику этого продавца, а user_messages_view похоже на почтовый ящик сообщений этого пользователя, отправленного и полученного, и пользователь может Выберите сообщение, чтобы открыть разговор. Именно тогда, когда пользователь получает сообщение, инициированное другим пользователем, в почтовом ящике показано неверное самоотверждение, а не фактическое сообщение. Несмотря на то, что счетчик непрочитанных сообщений правильно показывает нечитанные сообщения для этого пользователя. < /P> Как я могу решить проблему? /p>
