Beginner in CodeIgniter

[eluser]Avril[/eluser]
Hi!

I've decided to learn CodeIgniter to create a small but secure blog site for a client.
I'm a PHP & jQuery dev and I'm used to make custom CMS or edit existing once, but CI is very new to me so I could ask some bizar questions .

So I've just started and I'm already running into a problem ^^.

Here's what I get as error message:

A PHP Error was encountered

Severity: Notice

Message: Undefined property: Blog::$db

Filename: controllers/blog.php

Line Number: 7

and here's my code:

Code:

class Blog extends Controller{

    function index(){
    
        $q = $this->db->get('blog_posts');
        
        if( $q->num_rows() > 0){
        
            foreach( $q as $row ){
            
                $array[] = $row;
                
            }
            
            return $array;
            
        }
        
    }
    
}

Not realy sure what I'm doing wrong here?

Never mind, I've found it, I was working with the Controller instead of the Model. D'Oh!
