I still don't understand how JsObj works.. I've tried almost every
combination, it's more like luck that some stuff i do works.
def listLanguages(): LiftResponse = {
def displayLanguage(l: Locale): (String, String) = {
var r = l.getDisplayLanguage
if (l.getDisplayCountry != "")
r += " | " + l.getDisplayCountry
return (l.toString, r)
}
JsonResponse(JsObj(
"results" ->
JsArray(Locale.getAvailableLocales.flatMap(s =>
displayLanguage(s)) :_*)
))
}
Believe me, i tried every possible combination of JsObj in there, it
*always* got to nag something. We really need some samples for stuff
like that..
One time it tells me that it needs a List(String, String), as soon as
i have that, it want's a List(String, JsExp), so i change it to that,
then it complains again over the first problem..
it really is the big time killer for beginners to play around with
stuff like that because the API-Docs are too "dry" to understand
anything from it.
best regards.
