CakePHP 3 - 模型 - 从数组的第三层访问数据

Question

CakePHP 3

我的模型

用户有很多徽章

标题有很多徽章

徽章属于标题

徽章属于用户

在我的用户视图中，我想访问 Titles 的值，但我不知道如何访问。

**Users Controller**

public function view($id = null)
{
  $this->viewBuilder()->layout('admin');
  TableRegistry::get('Users');
    $user = $this->Users->get($id, [
        'contain' => ['Badges', 'Projects', 'Reports', 'Rewards']
    ]);
    $this->set(compact('user'));
    $this->set('_serialize', ['user']);
}





    UsersTable.php
    $this->hasMany('Badges', [
            'foreignKey' => 'user_id'
        ]);

    TitleTable.php
    $this->belongsTo('Users', [
        'foreignKey' => 'user_id',
        'joinType' => 'INNER'
    ]);
    $this->belongsTo('Titles', [
        'foreignKey' => 'title_id',
        'joinType' => 'INNER'
    ]);


    BadgesTable.php
    $this->hasMany('Badges', [
        'foreignKey' => 'title_id'
    ]);

                    (

                [[repository]] => Badges
            )
    )

[[new]] => 
[[accessible]] => Array
    (
        [*] => 1
    )

[[repository]] => Users

)

我想要的是从标题表中获取数据（即名称）

    [badges] => Array
         (
        [0] => App\Model\Entity\Badge Object
            (
                [id] => 1
                [user_id] => 1
                [title_id] => 11
                [created] => Cake\I18n\FrozenTime Object

Answer 1

在您的contain 中，您可以使用'Model.Model' 获取更多相关数据，如下所示：

$user = $this->Users->get($id, [
    'contain' => ['Badges.Titles', 'Projects', 'Reports', 'Rewards']
]);
