cakehp4:无法在hasone中保存关联

Question

我编写了以下代码来将数据从MailFormsController存储到客户和消息模型

控制器/MailFormsController.php

<?php
declare(strict_types=1);
namespace AppController;
use CakeDatasourceConnectionManager;
use CakeCoreExceptionException;
use CakeORMTableRegistry;
/**
* MailForms Controller
*
* @method AppModelEntityMailForm[]|CakeDatasourceResultSetInterface paginate($object = null, array $settings = [])
*/
class MailFormsController extends AppController
{
/**
* Index method
*
* @return CakeHttpResponse|null|void Renders view
*/
public function index()
{
if($_SERVER['REQUEST_METHOD'] == 'POST'){
// $this->loadModel('Customers');
$this->Customers = TableRegistry::get('customers');
$this->Messages = TableRegistry::get('messages');
$post_data = $this->request->getData();
$customerData = $this->Customers->newEmptyEntity();
$customerData = $this->Customers->patchEntity($customerData, $this->request->getData(), ['associated' => ['Messages']]);
if ($this->Customers->save($customerData)) {
$this->Flash->success(__('The site name has been saved.'));
return $this->redirect(['action' => 'index']);
} else {
$this->Flash->error(__('The entry data could not be saved. Please, try again.'));
}
}
}
}

查看模板模板/MailForms/index.php

<?php
echo $this->Form->create();
echo $this->Form->control('name');
echo $this->Form->control('mail');
echo $this->Form->control('messages.0.message_1');
echo $this->Form->control('messages.0.message_2');
echo $this->Form->control('messages.0.message_3');
echo $this->Form->button('POST', ['type' => 'submit']);

我已经在CustomersTable.php中与hasone for Messages建立了关联，但当我运行此程序时，数据只存储在Customers表中，而不存储在Messages表中。

请告诉我这个程序有什么问题，以及如何保存关联？

因为它是hasOne关系，所以每个客户只有一条消息，您的字段应该相应地命名：

echo $this->Form->control('message.message_1');
echo $this->Form->control('message.message_2');
echo $this->Form->control('message.message_3');
