Yii2 Querybuilder with searchmodel - php

Question

My searchmodel
$query = (new \yii\db\Query())
->select(['monthsubmit',"DATE_FORMAT(monthsubmit, '%m-%Y') as c_date", 'modeler', 'count(sku) as count'])
->from('sku3d')
->groupBy(['monthsubmit', 'modeler'])
->orderBy(['monthsubmit'=>SORT_DESC, 'modeler'=>SORT_DESC]);
$dataProvider = new ActiveDataProvider([
'query' => $query,
]);
My controller
$searchModel = new Sku3dSearch();
$dataProvider = $searchModel->search(Yii::$app->request->queryParams);
My gridview
<?php echo GridView::widget([
'dataProvider' => $dataProvider,
'filterModel'=>$searchModel,
'pjax'=>true,
'panel' => [
'type' => GridView::TYPE_PRIMARY,
'heading' => '<h3 class="panel-title"><i class="glyphicon glyphicon-user"></i>Submitted SKU by Month</h3>',
],
'columns' => [
[
'attribute'=>'monthsubmit',
'width'=>'310px',
'filter'=>ArrayHelper::map(Sku3d::find()->orderBy('monthsubmit')->asArray()->all(), 'monthsubmit', 'monthsubmit'),
'group'=>true,
],
[
'attribute'=>'modeler',
'width'=>'180px',
'group'=>true,
],
'count:text:Total Sku',
]
]);
?>
At first I didn't use querybuilder in searchmodel but in controller and everything worked fine. But I need to filter it also so i moved my querybuilder into searchmodel.
When I did this, it had error "Getting unknown property:app\models\Sku3d::count".
How can I call the 'count(sku) as count' to my gridview. And also it look like my groupBy(['monthsubmit', 'modeler']) not working also.
Please tell me where I'm wrong.
Thank you.

In your searchmodel add a publica var
class Sku3dSearch extends Sku3d
{
public $count;
/**
* #inheritdoc
*/
public function rules()
......
$query = (new \yii\db\Query())
->select(['monthsubmit',"DATE_FORMAT(monthsubmit, '%m-%Y') as c_date", 'modeler', 'count(sku) as count'])
->from('sku3d')
->groupBy(['monthsubmit', 'modeler'])
->orderBy(['monthsubmit'=>SORT_DESC, 'modeler'=>SORT_DESC]);
$dataProvider = new ActiveDataProvider([
'query' => $query,
]);
}
