Django: Изменение поля модели в базе данных при нажатии на кнопку

Я создаю веб-приложение для пиццерии. Нужно добавить действие: при нажатии на кнопку "Заказ доставлен" статус заказа должен меняться на "Заказ выполнен". Как это сделать? Необходимо, чтобы при нажатии на кнопку поле статуса в заказе менялось
