Yii Active Record 如何在 DataProvider 中为每个模型安装场景？

public function searchView()
            {
                $criteria = new CDbCriteria([
                    'select' => 'last_comment,name,data,cdate,mdate,edate,coperator,eoperator',
                    'with' => ['houses', 'houses.city', 'houses.district', 'houses.street','stages']
                ]);
               $model = $this;
               //$model->scenario = 'searchView'; this is for dataprovider
                return new CActiveDataProvider($model , [
                    'criteria' => $criteria,
                    'sort' => [
                        'defaultOrder' => 'cdate DESC'
                    ],
                    'pagination' => $this->searchFrom || $this->searchTo || $this->district_key || $this->city_key ? false : ['pageSize' => 100]
                ])

;
                }

【解决方案1】：

您始终可以循环访问 CActiveDataProvider 的数据属性。数据是一个简单的模型数组

首先你需要将它存储在变量中：

$dataProvider = new CActiveDataProvider($model , [
                    'criteria' => $criteria,
                    'sort' => [
                        'defaultOrder' => 'cdate DESC'
                    ],
                    'pagination' => $this->searchFrom || $this->searchTo || $this->district_key         || $this->city_key ? false : ['pageSize' => 100]
                    ]);

你可以循环遍历模型：

foreach($dataProvider->data as $model){
    $model->scenario = 'searchView';
}

您可以在每个模型上返回带有场景的数据提供者

return $dataProvider;

我希望这就是你所需要的
