how load helper in a model?

Hi,

I need load a custom helper in a Model...

It's possible?

I need translate $validationsRules label

Some idea?

I think to load custom helper for get user lang and set label each validationRule

thanks

the idea is something like:

helper('admin_auth'); // method comprovacio_idioma_usuari()
$idioma = comprovacio_idioma_usuari();
protected $validationRules    = [
   'nom' => ['label' => lang('Admin.nom', [], $idioma), 'rules' => 'min_length[2]|max_length[100]|required']
];
