Django Serializer ничего не вставляет в базу данных (без ошибок)

Как я указал в заголовке, в мою базу данных ничего не вставляется, хотя другие поля вставляются. Моя цель состоит в том, чтобы принять json запрос на пост:

{
    "user": "0",
    "total_price":29.60,
    "type":"PENDING",
    "products": [{
        "id_product":"0"
        },{
        "id_product":"1"
        },
        {
        "id_product":"3"
        }
        ]

}

Я беру этот пост-запрос и пропускаю его через свой сериализатор, чтобы сохранить его в своей базе данных. поле products в json - это "список внешних ключей, указывающих на первичный ключ в модели Products.

".
