Question

如何在 yii ActiveRecord DadaProvider 中为每个模型安装场景；默认应该更新

public function afterFind()
{
   if ($this->scenario === 'searchView') {
            //myCode
   }
   parent::afterFind();
}
public function searchView()
{
        $criteria = new CDbCriteria([
            'select' => 'last_comment,name,data,cdate,mdate,edate,coperator,eoperator',
            'with' => ['houses', 'houses.city', 'houses.district', 'houses.street', 'stages']
        ]);
        return new CActiveDataProvider($this, [
            'criteria' => $criteria,
            'sort' => [
                'defaultOrder' => 'cdate DESC'
        ]);
}

我认为您在获取对象时无法指定您想要的场景，我看到的最接近的东西是扩展 CActiveDataProvider ：

class CustomActiveDataProvider extends CActiveDataProvider {

    protected function fetchData()
    {
        $data = parent::fetchData();
        foreach($data as $model) {
            // do what you wanted to do in the afterFind
            // $model->afterFindSearchView()
        }
        return $data;
    }
}

然后在你的模型中创建方法afterFindSearchView，并在调用数据提供者时这样做

return new CustomActiveDataProvider($this, [
        'criteria' => $criteria,
        'sort' => [
            'defaultOrder' => 'cdate DESC'
]);
