[英]Symfony2 Optional parameter in routing has no value
I am struggling with this detail while defining a route in Symfony2 在Symfony2中定义路线时,我在这个细节上苦苦挣扎
Mi routing: 小米路由:
blog:
path: /blog/{page}
defaults: { _controller: ManualRouteBundle:Blog:show, page: 33 }
My controller: 我的控制器:
<?php
namespace Manual\RouteBundle\Controller ;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
class BlogController extends Controller{
public function showAction($page){
return $this->render('ManualRouteBundle:Blog:show.html.twig') ;
}
}
My view: 我的观点:
Blog # {{page}}
When I try to access with this address 当我尝试使用该地址访问时
http://test/web/blog
instead of 代替
http://test/web/blog/1
I get this error 我得到这个错误
Variable "page" does not exist in ManualRouteBundle:Blog:show.html.twig at line 1
500 Internal Server Error - Twig_Error_Runtime
Isn't page value supposed to be 33? 页面值不应该是33吗?
I got the answer on #symfony, I have to pass the variable to the view. 我得到了#symfony的答案,我必须将变量传递给视图。
$this->render() like this: $this->render('show.html.twig', array('page' => $page));
Weird behavior imho. 怪异的行为恕我直言。
