Codeigniter: problem extending Database Driver

Im using Codeigniter 2.x and been trying to extend the database class and followed the wiki but im getting this error:

Fatal error: Uncaught Error: Call to undefined method MY_DB_mysqli_driver::where() in /system/libraries/Session.php on line 218

Error: Call to undefined method MY_DB_mysqli_driver::where() in /system/libraries/Session.php on line 218

On line 218 of /system/libraries/Session.php:

$this->CI->db->where('session_id', $session['session_id']);

My extended class is just the example from the wiki:

<?php
class MY_DB_mysqli_driver extends CI_DB_mysqli_driver
{
    public function __construct($params)
    {
        parent::__construct($params);
        log_message('debug', 'Extended DB driver class instantiated!');
    }

    public function get_first($table)
    {
        return $this->limit(1)->get($table);
    }
}

The error you're getting is actually correct. I just downloaded version 2 to make sure of it.

You're extending the CI_DB_mysqli_driver when what you're actually adding to it should be in the active records library and not the database driver.

Instead of extending your CI_DB_driver create an extension of CI_DB_active_record and add the get_first functionality in it.

I must add that if that function is all you want to add to your core I wouldn't even bother to extend the core with it, since you're just trading one line by another line, there's no gain in it.

Also, most of these extensions can be done in a good base Model instead of hacking into the core.
