Cakephp 3.4 всегда сохраняет первичный ключ как NULL

Я пытаюсь вставить в свою таблицу внутренних поставок, но хочу использовать свой собственный первичный ключ (release_note), а не автоматическое увеличение sql. Итак, я сделал поле release_note видимым с помощью

echo $this->Form->input('release_note', ['type' => 'text', 'id' => 'note']);

но каждый раз, когда я пытаюсь добавить новую отправку, текст, который я ввел в этот ввод, никогда не сохраняется и не отправляется в запрос sql, поэтому всегда по умолчанию используется значение NULL.

Это моя таблица внутренних отгрузок

Это мой метод добавления InwardsShipmentsController.

public function add()

        $inwardShipment = $this->InwardShipments->newEntity();
        if ($this->request->is('post')) {
            $inwardShipment = $this->InwardShipments->patchEntity($inwardShipment, $this->request->data);
            if ($this->InwardShipments->save($inwardShipment)) {
                $this->Flash->success(__('The {0} has been saved.', 'Inward Shipment'));
                return $this->redirect(['action' => 'index']);
            } else {
                $this->Flash->error(__('The {0} could not be saved. Please, try again.', 'Inward Shipment'));



            }
        }

а это мой add.ctp там скрипт для установки release_note внизу

Это сообщение об ошибке, которое я всегда получаю, поскольку вы можете видеть, что release_note даже нет в инструкции Insert.
