Итак, у меня есть точка входа /surveys//. Я обращаюсь к ней PUT методом для обновления данных и передаю следующие данные:
{
"id": 135,
"statuses": [],
"name": "asdasdasdsad",
"description": "asdasdasdasd",
"unique_url": "eecc2d5de02543bfba909d1660f8798f",
"is_active": false,
"is_anonymous": false,
"have_answers": false,
"created_at": "2018-08-30T20:02:29.231761",
"answers_count": 0,
"expiration_date": null,
"creator": 167
}
И у меня вылетает ошибка:
Cannot set values on a ManyToManyField which specifies an intermediary model. Use surveys.Status's Manager instead.
