I am new with Yii2, using Gii tool,I have created the model and CRUD components for simple 'Message' class with one field 'content' mapped to tbl_message.
I am getting error, When trying to retrieve one message object by using findByPk function as follows:
$message = Message::model()->findByPk(4);
Error message:
Call to undefined method app\models\Message::model()
This would be enough :
$message = Message::findOne(4)
