如何在CakePHP 3.x中按单值查询HasMany关联

// 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 view($id)
    {
        $user = $this->Users->find()
            ->contain(['Posts' => function ($q) use ($id) {
                return $q->matching('Posts', function ($q) use ($id) {
                    return $q->where(['Posts.id' => $id]);
                });
            }])
            ->where(['Users.id' => $id])
            ->first();

        $this->set('user', $user);
    }
}

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

<h1><?= $user->name ?></h1>

<h2>Posts:</h2>
<ul>
    <?php foreach ($user->posts as $post): ?>
        <li><?= $post->title ?></li>
    <?php endforeach; ?>
</ul>
