使用 kohana 3.3 使用 request->param() 检索单个记录为 NULL

Question

我尝试使用kohana框架，但我有一个小问题，当我试图从我的数据库表检索单个记录。我的表:

ads
 id_ads
 title_ads
 description_ads

我的控制器:

public function action_single()
{
    $ads_id = $this->request->param('id_ads');
    $ads = ORM::factory('ads', $ads_id);
    $view = new View('ads/single');  // load the view/ads/single.php
    $view->set('ads', $ads);        // set 'ads' object to view
    $this->template->set('content', $view);
}

我的观点

<h2><?php echo $ads->title_ads; ?></h2>
<pre><?php echo $ads->description_ads; ?></pre>

当我去到localhost/kohana/index.php/ads/single/1浏览器显示什么，问题在哪里?

Answer 1

try this:

$ads_id = $this->request->param('id_ads');
$ads =ORM::factory('ads'->find($ads_id);

或

$ads_id = $this->request->param('id_ads');
$ads =ORM::factory('ads')->where("id","=",$ads_id)->find();

传递参数，我认为，是更好(更容易)扩展Controller_Template以这种方式:

class Controller_News extends Controller_Template{
...
   public function action_single()
   {
     ...
     $view->ads=$ads;
     $this->template->content = $view;
   }
}
