yii的构造函数 [ 2.0 版本 ]

yii的构造函数方法跟thinkphp差不多，只不过得先定义一个属性，直接贴代码：

public function init(){
      parent::init();

      $this->dish = new Dish();
    }

    public function actionIndex($id)
    {
      $storeid=Yii::$app->request->get('id');
      $where['storeid'] = $storeid;
      $count=$this->dish->find()->where($where)->count();
      $page=new Pagination(['defaultPageSize'=>20,'totalCount'=>$count]);
      $msgs=$this->dish->find()->where($where)->orderBy('dishid desc')->orderBy('status asc')->offset($page->offset)->limit($page->limit)->all();
      return $this->render('index',['page'=>$page,'msgs'=>$msgs]);
    }

还没有完，要在开头public一下哦：代码如下：

class DishController extends Controller
{
    /**
     * @inheritdoc
     */
    public $dish;
