Symfony2 Route global {_locale} requirements

Question

I have in my routing.yml specified the parameter _locale requirements in every single route and I think that must be something to simplify this situation.

routing.yml

ProjectBaseBundle_index:
    pattern:  /{_locale}
    defaults: { _controller: ProjectBaseBundle:Default:index }
    requirements:
        _locale: en|es

ProjectBaseBundle_privacy:
    pattern:  /privacy/{_locale}
    defaults: { _controller: ProjectBaseBundle:Default:privacy }
    requirements:
        _locale: en|es

.....

ProjectBaseBundle_legal:
    pattern:  /legal/{_locale}
    defaults: { _controller: ProjectBaseBundle:Default:legal }
    requirements:
        _locale: en|es

I am using Symfony2.1 beta 3

Is possible to specify a global _locale requirements for all my routes?

Answer 1

I have discovered a way to do that:

Using a "master" routing to import the routing config. As my bundles usually have too much information, I have been separating the controllers, resources and routes in differents "modules". As result of that approach, I have discovered this:

Master routing.yml

ProjectBaseBundle_default:
    resource: "@ProjectBaseBundle/Resources/config/routing-default.yml"
    prefix:   /{_locale}/project/
    requirements:
        _locale: en|es|de|fr

Child routing-default.yml

ProjectBaseBundle_default_privacy:
    pattern:  /privacy
    defaults: { _controller: ProjectBaseBundle:Default:privacy }

ProjectBaseBundle_default_legal:
    pattern:  /legal
    defaults: { _controller: ProjectBaseBundle:Default:legal }

ProjectBaseBundle_default_usage:
    pattern:  /usage
    defaults: { _controller: ProjectBaseBundle:Default:usage }

With this routing config, I minimize the places where need to write the locale requirements.
