функция отправки django не сохраняет данные в базе данных

#python #html #django #web-applications

#python #HTML #django #веб-приложения

Вопрос:

Я только начал использовать django, и это мое первое приложение. я создал «контактную форму» в зависимости от нескольких руководств, которые я видел, но она не сохраняет данные в базе данных и не направляет меня на HTML-страницу «Спасибо».

перепробовал много сценариев, но ни один из них не сработал, кто-нибудь может помочь? я открыт для изменения любой вещи в коде, чтобы заставить его работать и сохранить данные, которые мне нужно сохранить.

Комментарии:

1. Я думал, что форма должна быть определена внутри тега <form> </form> . Я не вижу этого в твоем form.html

2. спасибо за ваш ответ, я все изменил, и это сработало
