Yii Framework 中CGridView默认排序的设置 [ 技术分享 ]

默认生成的代码CGridView的dataProvider是$model->search(); 我们找到模型类的search方法：

public function search()
{
    // Warning: Please modify the following code to remove attributes that
    // should not be searched.
    $criteria=new CDbCriteria;
    $criteria->compare('title',$this->title,true);
    return new CActiveDataProvider(get_class($this), array(
        'pagination'=>array(
        'pageSize'=>20,//设置每页显示20条
    ),
    'sort'=>array(
        'defaultOrder'=>'create_time DESC', //设置默认排序是create_time倒序
    ),
    'criteria'=>$criteria,
    ));
}
