yii去掉自动排序功能

Yii去掉自动排序功能并自定义排序

    public function search($params)
    {
        $query = SvnManage::find()->addOrderBy([
            'created_at' => SORT_DESC   // 自定义按创建时间倒序排序
        ]);
        // add conditions that should always apply here
        $dataProvider = new ActiveDataProvider([
            'query' => $query,
            'sort' => false,    // 去掉自动排序功能
        ]);
