Caching an action in a multi-language website using Play Framework's Cached API

Question

In order to cache actions per label and language for a given number of seconds, I wrote the following helper method (where label, is the name I give to my action):

Answer 1

Maybe the problem is in the getLanguage method. Try this, as recommended by the docs:

def getLanguage(request: RequestHeader): String = {
    request.acceptLanguages
           .map(_.code)
           .headOption
           .getOrElse(helpers.LanguageHelpers.FRENCH)
}

Also, take a look at Controller.request2lang() method and see if it could be helpful to you.
