Я сравнительно новичок в разработке Django rest API. В настоящее время я работаю над сохранением Organisation class и при обновлении этой модели я столкнулся с показанной ниже ошибкой:
Ошибка: у объекта 'tuple' нет атрибута '_committed '
Просто чтобы все знали: ошибка возникла только для вызова PUT, а не для вызова POST.
