Set a default variable in my controller constructor

[eluser]sohei[/eluser]
Hi all,
I have some variables that appears often in my controller.
So I want to define them in my constructor:

Code:

function __construct()
        {
            parent::__construct();
$this->load->model('artist_model');
            $data['works'] = $this->artist_model->getWorks(8);
        }

But when I call them in my view, it doesn't work.. Can anyone tell me why?

Thanks,
sohei
