Symfony2 default locale in routing

Question

I have a problem with routing and the internationalization of my site built with Symfony2.
If I define routes in the routing.yml file, like this:

This is what I use for automatic locale detection and redirection, it works well and doesn't require lengthy routing annotations:

routing.yml

The locale route handles the website's root and then every other controller action is prepended with the locale.

locale:
  path: /
  defaults:  { _controller: AppCoreBundle:Core:locale }

main:
  resource: "@AppCoreBundle/Controller"
  prefix: /{_locale}
  type: annotation
  requirements:
    _locale: en|fr

CoreController.php

This detects the user's language and redirects to the route of your choice. I use home as a default as that it the most common case.

public function localeAction($route = 'home', $parameters = array())
{
    $this->getRequest()->setLocale($this->getRequest()->getPreferredLanguage(array('en', 'fr')));

    return $this->redirect($this->generateUrl($route, $parameters));
}

Then, the route annotations can simply be:

/**
 * @Route("/", name="home")
 */
public function indexAction(Request $request)
{
    // Do stuff
}

Twig

The localeAction can be used to allow the user to change the locale without navigating away from the current page:

{{ targetLanguage }}

Clean & simple!
