Помощь с кодом входа в CodeIgniter

Question

Я получаю сообщение об ошибке с этой строкой:

$result = $this->user->login($username, $password);

Выполнение вызова метода или объекта, который не определен.

Контроллер:

<?php if (! defined('BASEPATH')) exit(' No direct script access allowed');

class verifyLogin extends CI_Controller{

    function _contruct()
    {
        parent::_construct();
        $this->load->model('User','',TRUE);

    }

    function index()
    {
        //validate the credentials
        $this->load->library('form_validation');

        $this->form_validation->set_rules('username', 'Username','trim|required|xss_clean');
        $this->form_validation->set_rules('password', 'Password','trim|required|xss_clean|callback_check_database');

        if($this->form_validation->run() == FALSE)
        {
            //if validation fails then redirect to login page
            $this->load->view('login_view');
        }
            else
            {
                //go to private area
                redirect('home', 'refresh');
            }
    }

    function check_database($password)
    {

        //validate against database 
        $username = $this->input->post('username');

        //query the database
        $result = $this->user->login($username, $password);

        if($result)
        {
            $sess_array = array();
            foreach($result as $row)
            {
                $sess_array = array(
                'id' => $row->id, 
                'username' => $row->username
                );
                $this->session->set_userdata('logged_in', $sess_array);
            }
                return TRUE;
        }
        else
        {
            $this->form_validation->set_message('check_database', 'Invalid username or password');
                return false;
                }
            }
}

?>

Модель:

<?php
class User extends CI_Model
{
    function login($username, $password)
    {
        $this-> db -> select('id, username, password');
        $this-> db -> from('users');
        $this-> db -> where('username = ' . "'" . $username . "'");
        $this-> db -> where('password = ' . "'" . MD5($password) . "'");
        $this-> db -> limit(1);

        $query = $this -> db -> get();

        if($query -> num_rows() == 1)
        {
            return $query->result();
        }
            else
            {
                return false;
            }

    }
}
