Play 2.3.x Scala - How to display json data on view?
Question
I am coming from the Node world and I am having trouble wrapping my head passing json to the view and then displaying data.
I am hitting an api to fetch 2 profiles. The res.body is json. The response is fairly large - but now I only want to display some data in my view.
// Application.scala
val profile1 = WS.url(player1URL).get()
val profile2 = WS.url(player2URL).get()
Future.sequence(Seq(profile1, profile2)).map {
response => Ok(views.html.index.render(
Json.obj("player1" -> response(0).json, "player2" -> response(1).json)))
}
//index.scala.html
@(z: play.api.libs.json.JsObject)
<body>
@z.player1 //value player1 is not a member of play.api.libs.json.JsObject
// ideally I want
// z.player1.battleTag //displays battle tag
// z.player1.paragonLevel //displays paragon level
</body>
I can display my json as string or even as json. But I cannot access the values by keys. I just want to display 3 or 4 items from each player as html. Then I can clean it up with some css later.

You can access you json by using code similar to this:
@{(z\"player1"\"battleTag").as[String]}
Or even:
<script>
var jsono = @Html(z.toString) ;
alert(jsono.player1.battleTag)
</script>
