Question

I have a problem with default parameters and using Play Json Read. Here is my code:

  case class Test(action: String, storeResult: Option[Boolean] = Some(tru         


        

Answer 1

It looks as if support for default parameters is in version 2.6.

A workaround for prior versions is to do something like the following:

object TestBuilder {
  def apply(action: String, storeResult: Option[Boolean], returndata: Option[Boolean]) =
    Test(
      action, 
      Option(storeResult.getOrElse(true)), 
      Option(returndata.getOrElse(true))
    )
}

implicit val testReads: Reads[Test] =
  (
    (JsPath \\ "action").read[String](minLength[String](1)) and
    (JsPath \\ "store_result").readNullable[Boolean] and
    (JsPath \\ "returndata").readNullable[Boolean]
  )(TestBuilder.apply _)
