Usage

Everything is same in the twig files. For example, if you have a route that does not have any relation with translation like admin just use:

admin:
    pattern:  /admin
    defaults: { _controller: ACMEDemoBundle:Admin/Default:index }

But you have translation aware route like register than use like that:

site_register_tr:
    pattern: /ajax/kayit-ol
    defaults: { _controller: ACMEDemoBundle:Register:register }
site_register_en:
    pattern: /ajax/register
    defaults: { _controller: ACMEDemoBundle:Register:register }
