Given the following route

Route::get('groups/(:any)', array('as' => 'group', 'uses' => 'groups@show'));

And the URL I would like to use,

http://www.example.com/groups/1

I would like to be able to use the (:any) value in my controller.

My controller looks like

class Groups_Controller extends Base_Controller {

    public $restful = true;    

    public function get_show($groupID) {
        return 'I am group id ' . $groupID;
    }  


}

How is this possible to do? I have tried a few things including the following

Route::get('groups/(:any)', array('as' => 'group', 'uses' => 'groups@show((:1))'));

but it did not work.

UPDATE

Anytime I try to pass in the arguments as show above i get a 404 error.

Thanks for the help!
