常规的delete方法如下：

/** 
* Deletes a particular model.
* If deletion is successful, the browser will be redirected to the 'index' page.
*/
public function actionDelete()
{ 
if(Yii::app()->request->isPostRequest)
{ 
// we only allow deletion via POST request
$this->loadModel()->delete();

// if AJAX request (triggered by deletion via admin grid view), we should not redirect the browser
if(!isset($_GET['ajax']))
$this->redirect(array('index'));
} 
else
throw new CHttpException(400,'Invalid request. Please do not repeat this request again.');
}

142 ),
143 ),

但是如果在别的地方你简单的使用 createUrl来创建的都是GET REQUEST,无法删除记录的

Error 400

解决方法：

16 <?php
17 echo CHtml::link(CHtml::encode('删除巡察记录'), array('/***/default/delete', 'id'=>$id),
18 array(
19 'submit'=>array('/***/default/delete', 'id'=>$id),
20 'class' => 'delete','confirm'=>'This will remove the image. Are you sure?'
21 )
22 );
23 ?>
