Unknown Method – yii\base\UnknownMethodException
Calling unknown method: yii\db\ActiveQuery::getCount()
my controller
public function actionIndex()

$sql = "SELECT presensi.presensi_tanggal 'tanggal', sum(if( hadir.keteranganhadir_id='1',1,0)) 'hadir', sum(if( hadir.keteranganhadir_id='2',1,0)) 'tidak_hadir', count(*) 'total' FROM hadir, keteranganhadir, presensi where hadir.keteranganhadir_id = keteranganhadir.keteranganhadir_id and hadir.presensi_id = presensi.presensi_id group by presensi.presensi_tanggal";

'tanggal',
'hadir',

How can i fix the problem?

Answer 1

Gridview looks for dataprovider, not array of activerecord models you have sent:
http://www.yiiframework.com/doc-2.0/yii-data-sqldataprovider.html
in your controller/actionIndex
$count = Yii::$app->db->createCommand('
SELECT COUNT(*) FROM user WHERE status=:status
', [':status' => 1])->queryScalar();
$dataProvider = new SqlDataProvider([
'sql' => 'SELECT * FROM user WHERE status=:status',
'params' => [':status' => 1],
'totalCount' => $count,
'sort' => [
'attributes' => [
'age',
'name' => [
'asc' => ['first_name' => SORT_ASC, 'last_name' => SORT_ASC],
'desc' => ['first_name' => SORT_DESC, 'last_name' => SORT_DESC],
'default' => SORT_DESC,
'label' => 'Name',
],
],
],
'pagination' => [
'pageSize' => 20,
],
]);
return $this->render('index', [
'hadir' => $dataProvider,
]);

Answer 2

You can try this:
In Controller.php file:
public function actionIndex()
{
$searchModel = new InvoiceSearch();
$dataProvider = $searchModel->search(Yii::$app->request->queryParams);
return $this->render('index', [
'searchModel' => $searchModel,
'dataProvider' => $dataProvider,
]);
}
Your view file seems to be true. Just add above code in your controller file.
