Symfony 2.1 set locale

Does anybody know how to set the locale in Symfony2.1?

I am trying with:

$this->get('session')->set('_locale', 'en_US');

and

$this->get('request')->setLocale('en_US');

but none of those has any effect, the devbar tells me:

Session Attributes: No session attributes

Anyway, it is always the fallback locale that is used, as defined in config.yml

(PS: I am trying to set up the translation system as described here

It's not:

$this->get('request')->setLocale('en_US');

But: 

$this->get('request')->getSession()->set('_locale', 'en_US');

From the symfony cookbook:

"Locale is stored in the Request, which means that it's not "sticky" during a user's request. In this article, you'll learn how to make the locale of a user "sticky" so that once it's set, that same locale will be used for every subsequent request."

http://symfony.com/doc/current/cookbook/session/locale_sticky_session.html

You can notice this when you set the locale and use the symfony profiler (in dev mode) to view the sub requests.

Even though the Symfony 2.1 states that you can simply set the locale via the Request or Session objects, I never managed to have it working, setting the locale simply has no effect.

So I ended up using a listener coupled with twig routing to handle the locale/language:

The listener:

namespace FK\MyWebsiteBundle\Listener;

use Symfony\Component\HttpKernel\Event\GetResponseEvent;
use Symfony\Component\HttpKernel\KernelEvents;
use Symfony\Component\EventDispatcher\EventSubscriberInterface;

class LocaleListener implements EventSubscriberInterface
    {
    private $defaultLocale;

    public function __construct($defaultLocale = 'en')
    {
        $this->defaultLocale = $defaultLocale;
    }

    public function onKernelRequest(GetResponseEvent $event)
    {
        $request = $event->getRequest();
        if (!$request->hasPreviousSession()) {
            return;
        }

        if ($locale = $request->attributes->get('_locale')) {
            $request->getSession()->set('_locale', $locale);
        } else {
            $request->setLocale($request->getSession()->get('_locale', $this->defaultLocale));
        }
    }

    static public function getSubscribedEvents()
    {
        return array(
            // must be registered before the default Locale listener
            KernelEvents::REQUEST => array(array('onKernelRequest', 17)),
        );
    }
}

Register the listener in service.xml:

<service id="fk.my.listener" class="FK\MyWebsiteBundle\Listener\LocaleListener">
    <argument>%locale%</argument>
    <tag name="kernel.event_subscriber"/>
</service>

The routing must look like:

homepage:
pattern:  /{_locale}
defaults: { _controller: FKMyWebsiteBundle:Default:index, _locale: en }
requirements:
    _locale: en|fr|zh

And handle the routing with:

{% for locale in ['en', 'fr', 'zh'] %}
    <a href="{{ path(app.request.get('_route'), app.request.get('_route_params')|merge({'_locale' : locale})) }}">
{% endfor %}

This way, the locale will automatically be set when you click on a link to change the language.

You set the locale in your parameters.yml.

[parameters]
...
    locale            = en

The fallback from your config.yml references %locale% which is the setting from the above parameters.yml file.

If you are trying to set it on-the-fly then this should work:

$this->get('session')->setLocale('en_US');

Test it by printing it out straight after:

print_r($this->get('session')->getLocale());

Edit

In 2.1 the locale is now stored in the request but can still be set in the session. http://symfony.com/doc/2.1/book/translation.html#handling-the-user-s-locale

$this->get('session')->set('_locale', 'en_US');
// setting via request with get and setLocale
$request = $this->getRequest();
$locale = $request->getLocale();
$request->setLocale('en_US');
