CActiveDataProvider根本不返回任何数据,仅返回结构

所以,我对yii有点新鲜,如果这听起来像一个蹩脚的问题,我很抱歉,但我有一些奇怪的行为。我正在尝试使用评论加载博客帖子,但actionView仅返回博客文章:

    public function actionView($id)
    {
           $model = $this->loadModel($id);
           $criteria = new CDbCriteria;
           $criteria->condition = 'postId = ' . $id;
           $criteria->order = 'commentTime desc';
           $criteria->with = array('user');
           $dataSet = new CActiveDataProvider('Comments', array(
             'criteria' => $criteria,
            )
           );
           echo "<pre>";
           print_r($dataSet);
           echo "</pre>";
           $this->render('view',array(
                    'model'=>$model,
                    'dataSet'=>$dataSet,

            ));
    }

现在是视图文件:

$this->renderPartial('_view',array('data'=>$model,));
$this->renderPartial('comments',array('data'=>$dataSet,));

有趣的是,根据日志,它甚至不是从评论表中选择,但是当我print_r时,我得到了表格的整个结构。

你正在为SQL注入(或者至少是一种可能性)建立自己的标准。如果你做这样的事情,你会得到你的结果吗?

public function actionView($id)
{
       // the with will load your comments through your Blog relationship
       // with the comments and then user your Comment -> User relationship as well
       // doing it this way eliminates the need for creating your own criteria object
       $model = Blog::model()->with('comments.user')->findByPk((int)$id);

       // we then set a defaultOrder here
       $dataSet = new CActiveDataProvider($model->comments, array(
           'sort'=>array(
               'defaultOrder'=>'commentTime desc',
           ),
        )
       );
       echo "<pre>";
       print_r($dataSet);
       echo "</pre>";

       ....

}
