Я пытаюсь сохранить клиента в модели заказа, но клиент не сохраняется, он показывает, что customer1@gmail.com должен быть экземпляром клиента. А также хочу сохранить продавца в модели заказа. Потому что продукт связан с продавцом. Когда я заказываю что-то и после того, как заказ сохранен, я должен видеть, у какого продавца я купил этот товар. Но здесь я не могу спасти продавца.
