42class PostsController extends Controller
43{
44    public function showAction()
45    {
46        $post = Post::findFirst();
47        $menu = Menu::findFirst();
48
49        $this->view->showNavigation = true;
50        $this->view->menu           = $menu;
51        $this->view->title          = $post->title;

56        $this->view->setVar('showNavigation', true);
57        $this->view->setVar('menu',           $menu);
58        $this->view->setVar('title',          $post->title);
