如何在CI的根文件夹中调用模型函数

Question

I am facing problem to call model from the root directory of CI folder. I have made apis in apis folder of ci but not inside of application folder. My all ci controller and model are reside in application folder like MY_PROJECT/application/controllers/Controllers_files.ext MY_PROJECT/application/models/Models_files.ext

but My apis are reside in MY_PROJECT/apis/apisfile.ext

error_reporting(E_ALL);
ini_set('display_errors', 1);
$apppath =  str_replace('apis', '', dirname(__FILE__));


include($apppath.'system/core/Model.php'); # if you didnt call this, it will throw  
# Fatal error: Class 'CI_Model' not found in E:\XAMPP\htdocs\Ab\My\E-Tech\application\models\product_model.php on line 3
require($apppath.'application/models/Notification_model.php'); # Model Name



$object  = new Notification_model();
$object->sendNotification($title='dharmendra', $message="chaudhary", $row_data, $type=1, $type_id=1);
