php - 如何在cakephp的组件中运行查询？

Question

我想在 cakephp 的组件文件中运行查询，但它显示 fatal error ，当我在 Controller 中执行此操作时它工作得很好，但我想在组件中执行。

 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'));
    } 


}

但是它显示这个错误

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

我该如何解决这个问题？提前致谢

我认为您没有指定您的组件使用 Auth 组件。您可以使用以下代码片段完成此操作:

public $components = array('Auth');
