How to let the user switch language in playframework 2

Question

In my play 1.x controller I had this:

public static void language(final String language){
    Lang.change(language);
    Header referer = request.headers.get("referer");
    if(referer == null){
        index();
    }else{
        redirect(referer.value());
    }
}

I would like to do the same in play 2.x but I have the impression that functionality is not available any more. This is what I have so far

  def language(language:String) = Action { implicit request =>

    // TODO change language

    val referer = request.headers.get("referer")
    referer.map{ referer =>
      Redirect(referer, FOUND);
    }getOrElse(
      Ok(views.html.index())
    )
  }

Answer 1

According to the documentation, in Play 2.4, inside the controller you can do

ctx().changeLang(new Lang(Lang.forCode("fr")));

You need to have a file conf/messages.fr so the application can refer to it for the message. You can start from the messages.default file and put your own messages.

You can store the language in the user session. You can find an example here

in fact there is no such system so you have to implement the language cookie yourself and pass the language to the template, see this example: github.com/julienrf/chooze/blob/master/app/controllers/… – Simon
