Kohana 未定义属性：Request::$action

Question

我正在尝试使用本教程设置我的第一个 Kohana 网页 - http://kohana-tutorial.blogspot.co.uk/2010/10/lesson-1-getting-started.html

按照说明操作后，出现此错误 - 未定义属性：第 49 行的 Request::$action。

这是与该行相关的代码，在 DefaultTemplate.php

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，这是渲染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();
    }
}

导致此错误的完整程序列表是：

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

如有任何帮助，我们将不胜感激。

本教程已有 4 年历史，所以可能有点过时了。

使用当前版本的 Kohana，您可以通过以下方式访问受保护的属性 $request->_action：

$this->request->action();

不要犹豫，检查 online documentation 甚至 system/classes/Kohana 中的源代码，它清晰且注释良好。

Kohana 未定义属性：Request::$action

Kohana Undefined property: Request::$action

php
