Yii2：调用未定义的方法backend \ models \ CreateBookings :: model（）

Question

Trying to fetch data from db

in controllers

$model = new CreateBookings();
$data = CreateBookings::model()->findByPk();

    return $this->render('view', [
                'data' => $data,
            ]);

in view :

<?php echo $data->booking_id?>

can somebody tell me what am i doing wrong?

Answer 1

The alternative for Yii1 findByPk in Yii2 is findOne($id)

 $model = CreateBookings::findOne($id); 

or the equivalent

 $model = CreateBookings::find()
->where(['id' => $id])
->one();

for your view you can use

 $data = CreateBookings::findOne($id)) ; 

and you should have the $id value.
