Symfony2 locale in route

Question

I followed Symfony2 doc http://symfony.com/doc/2.0/book/translation.html#the-locale-and-the-url and added locale to my routes. But, I can't find the way to carry locale through routes as I place {{ path('myroute') }} in twig template, but locale always gets fallback value instead taking current locale.

I tried {{ path('myroute', {'_locale': _locale}) }} but I got error "Variable "_locale" does not exist".

Any idea?

Answer 1

Fixed with {{ path('address', {'_locale': app.request.attributes.get('_locale')}) }} thanks to this thread http://www.mail-archive.com/[email protected]/msg34838.html.

Answer 2

In Symfony2.1 the locale is stored in the request, so you have to use this:

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

Two pages:

localhost.lo/xx/about

localhost.lo/xx/hello/{name}

where xx - several locales described in routing.yml

-- 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());
    }
}

Shorthand notation:

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