extend core class to have constructor input parameters.

[eluser]Hummer[/eluser]
Is it possible to extend a core class to have input parameters in the constructor?

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class MY_Model extends CI_Model {

var $input_parms = "";

public function __construct( $params )
{
$this->input_parms = $parms;
parent::__construct();

}
}


When I do this I get this warning:


Severity: Warning

Message: Missing argument 1 for MY_Model::__construct(), called in /var/www/html/codeigniter/system/core/Common.php on line 174 and defined

Filename: core/MY_Model.php

Line Number: 47




Should I be concerned about the warning?

Is the extended class incorrect?
