You'd want to use a Route Filter.

hi Garbee,

I have this folder to access the CRUD must be logged in

Route::group(array('before' => 'authSentry'), function()
{
	Route::resource('areas', 'AreasController');
});

I have this and another filter for access to shares

Route::filter('hasAccess', function($route, $request, $value)
{
	$user = Sentry::getUser();
	if (!$user->hasAccess($value)) return View::make('no-access');
});

Apparently it only works when it is declared in the constructor and I need it to work in all the methods (create, read, update, delete)

class AreasController extends BaseController {

    public function __construct()
    {
        $this->beforeFilter('hasAccess:areas');
    }

}
