Problem in generating query

[eluser]-spy-[/eluser]
this is weird, i can now generate the query, and retrieve data from the database, i tried again to put my query inside the controller, it's now working.. but unfortunately i can't make it in the model...

Fatal error: Call to a member function result() on a non-object in D:\Program Files\xampp\htdocs\pupcomm\system\application\views\profile\history.php on line 44

here's my code in profile.php

Code:

<?php
class Profile extends Controller {

    function Profile()
    {
        parent::Controller();    
    }
    
    function history()
    {
        $this->load->model('Student');
        $data['query'] = $this->Student->view_list();
        //$data['query'] = $this->db->query("SELECT * FROM SAMPLE_RECORDLIST");
        $this->load->view('profile/history', $data);    
    }
}
?>

here's my code in student.php

Code:

<?php
class Student extends Model {

    function Student()
    {
        parent::Model();
    }
    
    function view_list()
    {
        $query = $this->db->get('sample_recordlist');
        return $query->result();
    }
}
?>

hope you can help me again...
