CakePHP的3

我的模型

用戶具有許多徽章

標題具有許多徽章

徽章屬於標題

徽章屬於用戶

在我的用戶視圖中，我想訪問標題的值，但我不知道如何。

**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' 
    ]);

    ) 

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

[[repository]] => Users 

）

我想要的是得到標題表（姓名）

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

Answer 1

的數據在你contain，您可以使用'Model.Model'得到像這樣進一步的相關數據：

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