Я хочу принять указанные ниже данные JSON от пользователя и сохранить их в базе данных (MySql).
{
"organisation_name":"abc pqr"
}

Я переопределил первичный ключ по умолчанию для Django модели в каждом классе моей модели. Я просто хочу принять organisation_name от пользователя, а organisation_id должен быть сгенерирован в соответствии с принципами Первичный ключ . Я не понимаю, почему он запрашивает идентификатор_организации, поскольку я уже упоминал его как Первичный ключ в моей Django модели. Я также пытался отправить organisation_id с organisation_name в JSON, но он по-прежнему возвращает ту же ошибку.
