Yii多对多关系查询

Question

对于有许多客户端和拥有多个用户的客户端的用户，使用许多关系查询。尝试查看特定用户的特定客户记录。如果该客户端不与该用户关联，则重定向到其他页面。

// the relation in the client model 
public function relations() 
{ 
    // NOTE: you may need to adjust the relation name and the related 
    // class name for the relations automatically generated below. 
    return array(
       'owners'=>array(self::MANY_MANY, 'User','owner_client(owner_id, client_id)'), 
        ); 
} 

//the relation in the user model 
public function relations() 
{ 


    return array(

     'clients'=>array(self::MANY_MANY, 'Clients','owner_client(owner_id, client_id)'), 
    ); 
} 

//determine if user can view this client 
//client record 
     $client_record = Clients::model()->findByPk($id); 
     //many query to find users 
     $users = $client_record->owners; 

     //if user id is not found in array, redirect 
     if (!in_array(Yii::app()->user->id, $users)) 
     { 
      $this->redirect(array('/site/dashboard')); 
     } 

上面的代码重定向，尽管我知道客户是关系到登录

Answer 1

当你调用$users = $client_record->owners;用户，什么你找回你所有的用户模型是一个数组与当前客户端相关联。因此，您将整数与对象进行比较，这意味着您的in_array（）条件将始终失败。

我建议你建立一个条件查询来做你的验证检查。像这样的东西应该工作：

$model = Clients::model()->with(
    array(
     'owners'=>array(
      'select'=>'owner_id', 
      'condition'=>'user.id = '.Yii::app()->user->id, 
     ), 
    ) 
)->findByPk($id); 

if ($model === null) { 
    $this->redirect(array('/site/dashboard')); 
}
