Проблема с формой входа в систему Django: форма недействительна, несмотря на правильные учетные данные ⇐ Python

[Anonymous]

Я столкнулся с проблемой с моей формой входа в Django. Несмотря на предоставление правильных учетных данных, форма последовательно возвращается как недействительную. Вот подробное описание моей настройки и проблемы, с которой я сталкиваюсь. Аутентификация для обработки входа пользователя. Моя цель - аутентифицировать пользователей и перенаправить их на определенную страницу после успешного входа в систему. Тем не менее, проверка формы не выполняется, даже если учетные данные точны, а пользователь существует в базе данных.
