Fatal error when extending model in codeigniter 2.0

[eluser]Rahat Bashir[/eluser]
Hello guys,

Fatal error: Class 'MY_CI_Model' not found in C:\xampp\htdocs\accounting\application\models\save_journal_model.php on line 3

I have extended the CI_Model and named it as MY_CI_Model as below:

Code:

class MY_CI_Model extends CI_Model
{

    function __construct()
    {
        parent::__construct();
    }

// other methods here....

}

and put it in the application/libraries folder.

Now, I have created another model named Save_Journal_Model by extending MY_CI_Model and put in the application/models

Code:

class Save_Journal_Model extends MY_CI_Model
{
    function __construct() {
        parent::__construct();
    }
}

When i am calling methods of Save_Journal_Model from my controllers, i am getting the error.

I just can't extend my child model class, MY_CI_Model

can anyone help to overcome?

Should be

Code:

MY_Model extends CI_Model

and put it in application/core folder

Then

Code:

class Save_Journal_Model extends MY_Model
{
    function __construct() {
        parent::__construct();
    }
}
