$userResource = $app['rest']->resource('/users', new UsersController($app, $users));

$userResource->convert('user', function($user, Request $request) use ($users) {
	$id = $request->attributes->get('id');

$userResource->assertId('\d{2}');

$app->run();

That the point for
convert('user', function($user,
You are never use this part in the example
and even override it in the foreach.
