model's constructor with parameters

Hi everybody,

I'm facing the same pb: I wanted to add some parameters to the __construct() method of a model and I got the same error message.
After reading this topic, I now understand why, so I'm looking for a solution to suit my need and the only solution I found without hacking CI is to add a "create" method in every model which looks like:

PHP Code:

public static function create($id, $title, $body) {
    $retour = new Topic();

    $retour->set_id($id);
    $retour->set_title($title);
    $retour->set_body($body);

    return $retour;
} 


and I can use it like this:

PHP Code:

Topic::create($id, $title, $body); 


it's suitable but maybe there is a better solution

Do you think it's a good way to do it ?
Is there a better solution ?

Thanks
Vincent
