如何在CakePHP 3中列出hasMany关系中的对象？

// src/Model/Table/UsersTable.php

namespace App\Model\Table;

use Cake\ORM\Table;

class UsersTable extends Table
{
    public function initialize(array $config)
    {
        $this->hasMany('Posts');
    }
}

// src/Controller/UsersController.php

namespace App\Controller;

use App\Controller\AppController;

class UsersController extends AppController
{
    public function index()
    {
        $users = $this->Users->find()
            ->contain('Posts') // 使用contain方法来包含关联模型
            ->all();

        $this->set(compact('users'));
    }
}

<!-- src/Template/Users/index.ctp -->

<h1>Users</h1>

<table>
    <tr>
        <th>Username</th>
        <th>Posts</th>
    </tr>
    <?php foreach ($users as $user): ?>
    <tr>
        <td><?= $user->username ?></td>
        <td>
            <?php foreach ($user->posts as $post): ?>
                <?= $post->title ?><br>
            <?php endforeach; ?>
        </td>
    </tr>
    <?php endforeach; ?>
</table>
