kartik gridview (YII2)에서 평균 계산

Question

비용 회계 응용 프로그램을 만들고 있습니다. 그리고 어떤 경우에는 데이터를 합산하는 데 성공했지만 평균을 얻고 싶으면 오류가 발생합니다. 여기에 너무 많은 코드를 써야하지만, 아무런 결과가 없습니다. 내 데이터에서 평균을 얻으려면 어떻게해야합니까?

이것은 이미 대답 질문이었고 정답이었다,하지만 난 당신이 그림 아웃하기를 수없는 생각 해결책.

이제보기 페이지에이 코드를 추가하고

<?php 

use yii\helpers\Html; 
use yii\widgets\DetailView;

$this->title = $model->rm_code;

$this->params['breadcrumbs'][] = $this->title;
