路径中的Symfony2语言环境

Question

我关注了Symfony2 doc http://symfony.com/doc/2.0/book/translation.html#the-locale-and-the-url并在我的路线中添加了区域设置。但是，当我将{{path（'myroute'）}}放置在twig模板中时，我找不到通过路由进行语言环境的方法，但语言环境总是得到后备值而不是当前语言环境。

我尝试{{path（'myroute'，{'_ locale'：_ locale}）}}但我收到错误“变量”_locale“不存在”。

有什么想法吗？

Answer 1

由于此帖子http://www.mail-archive.com/symfony-users@googlegroups.com/msg34838.html已修复{{ path('address', {'_locale': app.request.attributes.get('_locale')}) }}。

Answer 2

在Symfony2.1中，语言环境存储在请求中，因此您必须使用它：

{{ path('address', {'_locale': app.request.locale}) }}

两页：

localhost.lo / XX /约

localhost.lo / XX /你好/ {名称}

其中xx - routing.yml中描述的几个语言环境

- routing.yml

home:
  resource: "@JetInformBundle/Resources/config/routing.yml"
  prefix: /{_locale}
  requirements:
    _locale: ^en|de|ru|uk|pl$

- JetInformBundle routing.yml

hello:
  pattern:  /hello/{name}
  defaults: { _controller: JetInformBundle:Default:index, name: 'alexander' }

about:
  pattern:  /about
  defaults: { _controller: JetInformBundle:Default:about }

- DefaultController.php

<?php

namespace Jet\InformBundle\Controller;

use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Template;
use Symfony\Component\HttpFoundation\Request;

class DefaultController extends Controller
{
    public function indexAction($name, Request $request)
    {
        return $this->render('JetInformBundle:Default:index.html.twig',
                             array('name' => $name, 'matches' =>     $this->matchAction($request)));
    }

    public function aboutAction(Request $request)
    {
        return $this->render('JetInformBundle:Default:about.html.twig',
                              array('matches' => $this->matchAction($request)));
    }

    protected function matchAction(Request $request)
    {
        return $this->get('router')->match($request->getRequestUri());
    }
}
