如何在CakePHP的組件中運行查詢？

Question

我想在cakephp中的組件文件中運行查詢，但它顯示致命錯誤，當我在控制器中執行此操作時，它工作得很好，但我想在組件中執行此操作。

function product_check(){ 

$this->User = ClassRegistry::init('User'); 
$this->UserNode = ClassRegistry::init('UserNode'); 
$this->ProductsUserNode = ClassRegistry::init('ProductsUserNode'); 

    $conditionss = array(
     # http://book.cakephp.org/2.0/en/models/retrieving-your-data.html 
     'OR' => array(
      array('ProductsUserNode.'. NODE_ID => $this->Auth->user(NODE_ID)), 
      array('ProductsUserNode.'. NODE_ID => $this->Auth->user(NODE_IDX)), 
     ), 
    ); 

    $productcheck = $this->User->UserNode 
           ->ProductsUserNode 
           ->find(
            'first' 
            , array(
              'conditions' => $conditionss 
            ) 
           ); 

    $active = $productcheck['ProductsUserNode']['is_active']; 
    if ($active == "0") 
    { 
     $this->Session->setFlash('You Are Deactived For This Product'); 
     $this->redirect(array('controller'=>'events','action'=>'view_dashboard')); 
    } 


} 

，但它表明這個錯誤

Fatal Error 
Error: Call to a member function user() on a non-object 

我該怎麼辦解決這個問題？由於提前

Answer 1

我想你不要指定你的組件使用Auth組件。你可以用下面的代碼片段做：

public $components = array('Auth'); 

參見Using other Components in your Component

Answer 2

嘗試在你的情況是用戶，這應該idealy工作，只要確保你必須

$this->ModelName = ClassRegistry::init('ModelName'); 

加載在product_check（）用戶模式：

model : User.php 

和表爲

users 

希望能幫到你！
