Php Kohana未定义属性：请求：：$action

我正在尝试使用本教程设置我的第一个Kohana网页-

按照说明操作后，我在第49行留下了这个错误-未定义的属性：Request:：$action

这是DefaultTemplate.php中与该行相关的代码

48   if (!$view){
49       $view = 'pages/'.$this->request->controller().'/'.$this->request->action.'_tpl';
50     }
51     $this->template->content = View::factory($view, $this->data);
52   }
53 }
54 ?> 

这是由News.php调用的，它是呈现某些内容的标准调用

class Controller_News extends Controller_DefaultTemplate {
    public function  __construct(\Request $request, \Response $response) {
        parent::__construct($request, $response);
    }
    public function action_index(){
        $this->render();
    }
}

用于获取此错误的程序的完整列表为：

APPPATH/classes/Controller/DefaultTemplate.php [ 49 ] » Kohana_Core::error_handler(arguments)
APPPATH/classes/Controller/News.php [ 13 ] » Controller_DefaultTemplate->render()
SYSPATH/classes/Kohana/Controller.php [ 84 ] » Controller_News->action_index()

任何帮助都将不胜感激。

本教程已有4年历史，因此可能有点过时

使用当前版本的Kohana，您可以通过以下操作访问受保护的属性

$request->\u action

：

$this->request->action();

请毫不犹豫地检查

system/classes/Kohana

中的源代码，这些代码清晰且注释良好
