Symfony2如何检查i18n关闭当前操作（路由）的操作或模板？

Question

I would like to switch off the language switcher for actions that has i18n disabled in route. I do not want to hardcode actions identifiers anywhere, instead I would like to get information about status of i18n for current template/action.

/**
 * @Route("/path", name="route_name", options={"i18n" = false})
 * @Template("someAppBundle:Frontend/Home:something.html.twig")
 */
public function somethingAction()
{
    //How to check here if i18n is switch off?
    //How to check it directly in twig template?
    return array();
}

Answer 1

you can access route options via

$request->attributes->get('i18n')

or (in twig):

app.request.attributes.get('i18n')
