playframework - Scala foreach member variable -

-

is there way loop each member variable of class? it's trivial lists , arrays have construct case class each json field mapping member variable use play framework's reads/validator api

did mean this:

case class someclass(a: int, b: int) someclass(1,2).productiterator.foreach{ => println(a)}

this give output of: 1 2

or if trying construct object json. can define reads in case class deserialises json object :

override def reads(json: jsvalue): jsresult[someclass] = jssuccess(someclass(     (json \ "a").as[int],     (json \ "b").as[int]   )   )

then use deserialisation:

val json = json.obj() //your json json.validate[someclass]  json.fold(   errors => {     json.obj("status" -> "not ok", "message" -> jserror.tojson(errors))   },   preset => {     json.obj("status" -> "ok")   } )
