Actually I am trying to save the same data again in the database. So I retrieved the value from the db and then tried to save it again. But I am getting an error when I call the save function.

    Symfony \ Component \ Debug \ Exception \ FatalErrorException (E_ERROR) 
    Call to undefined method stdClass::save()
    Open: C:\xampp\htdocs\psi-aims\app\models\Orders.php
    public static function updateByOrderId($orderId)
    {
     /**
     *   Copy the Original Row with statusId As INACTIVE and refId AS PRIMARY KEY 
     **/
     $currentOrders = Orders::getForCopy($orderId);
     $currentOrders->mstStatus_id = 2;
     $currentOrders->save();
