Решил сделать такой простой сайт на джанго, типо Pinterest.
Сделал Detail и Create.
В форие создания поста пишу заоловок,
Загружаю картинку,
Нажимаю кнопку и вылазеет сообщение "файл не загружен".
Думаю: "Наверное она сохранилась", смотрю её нет.

В модели я написал что б картинка сохранялась в папку static/images
но джанго в корневой папке проекта создаёт images/static/images и сохраняет туда картинку.
(так происходит когда я загружаю их через админку)
