yii2 使用gii自动生成代码怎么添加分页

在搜索模型例如FeedbackSearch.php中的search方法中添加

"pagination" => [
                "pageSize" => 5,
            ],

例如：

public function search($params)
    {
        $query = Feedback::find();


        // add conditions that should always apply here


        $dataProvider = new ActiveDataProvider([
            "query" => $query,
            "pagination" => [
                "pageSize" => 5,
            ],
        ]);


        $this->load($params);


        if (!$this->validate()) {
            // uncomment the following line if you do not want to return any records when validation fails
            // $query->where("0=1");
            return $dataProvider;
        }


        // grid filtering conditions
        $query->andFilterWhere([
            "id" => $this->id,           
            "ctime" => $this->ctime,
            "utime" => $this->utime,
        ]);
