Symfony2 locale in route - php

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/symfony-users#googlegroups.com/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

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