Marshalling Nested User Objects in Sangria

Question

I have the following input objects:

val BusinessInputType = InputObjectType[BusinessInput]("BusinessInput", List(
    InputField("userId", StringType),
    InputField("name", StringType),
    InputField("address", OptionInputType(StringType)),
    InputField("phonenumber", OptionInputType(StringType)),
    InputField("email", OptionInputType(StringType)),
    InputField("hours", ListInputType(BusinessHoursInputType))

  ))


 val BusinessHoursInputType = InputObjectType[BusinessHoursInput]("hours",  List(
    InputField("weekDay", IntType),
    InputField("startTime", StringType),
    InputField("endTime", StringType)
  ))

And here are my models with custom Marshalling:

case class BusinessInput(userId: String, name: String, address: Option[String], phonenumber: Option[String], email: Option[String], hours: Seq[BusinessHoursInput])

object BusinessInput {

  implicit val manual = new FromInput[BusinessInput] {
    val marshaller = CoercedScalaResultMarshaller.default

    def fromResult(node: marshaller.Node) = {
      val ad = node.asInstanceOf[Map[String, Any]]

      System.out.println(ad)
      BusinessInput(
        userId = ad("userId").asInstanceOf[String],
        name = ad("name").asInstanceOf[String],
        address = ad.get("address").flatMap(_.asInstanceOf[Option[String]]),
        phonenumber = ad.get("phonenumber").flatMap(_.asInstanceOf[Option[String]]),
        email = ad.get("email").flatMap(_.asInstanceOf[Option[String]]),
        hours = ad("hours").asInstanceOf[Seq[BusinessHoursInput]]

      )
    }
  }
}



case class BusinessHoursInput(weekDay: Int, startTime: Time, endTime: Time)

object BusinessHoursInput {

  implicit val manual = new FromInput[BusinessHoursInput] {
    val marshaller = CoercedScalaResultMarshaller.default
    def fromResult(node: marshaller.Node) = {
      val ad = node.asInstanceOf[Map[String, Any]]
      System.out.println("HEY")

      BusinessHoursInput(
        weekDay = ad("weekDay").asInstanceOf[Int],
        startTime = Time.valueOf(ad("startTime").asInstanceOf[String]),
        endTime = Time.valueOf(ad("endTime").asInstanceOf[String])
      )
    }
  }


}

My question is: when I have a nested InputObjectone that has custom Marshalling, I don’t see that sorting BusinessHoursInputcauses a call before it BusinessInputis sorted. I noticed this because the expression “hey” is never executed before the ad is “ad” printed BusinessInput. This causes problems later when I try to insert the clock field BusinessInputin the database because it cannot pass it to the object BusinessHoursInput. In Sangria, it is not possible to configure custom nested marshal objects before the parent is configured?

, BusinessInput . Argument BusinessInput.

FromInput - , , . , :

case class BusinessInput (userId: String, name: String, address: Option [String], phonenumber: Option [String], email: Option [String], hours: Seq [BusinessHoursInput])

object BusinessInput {
  implicit def manual(implicit hoursFromInput: FromInput[BusinessHoursInput]) = new FromInput[BusinessInput] {
    val marshaller = CoercedScalaResultMarshaller.default

    def fromResult(node: marshaller.Node) = {
      val ad = node.asInstanceOf[Map[String, Any]]

      BusinessInput(
        userId = ad("userId").asInstanceOf[String],
        name = ad("name").asInstanceOf[String],
        address = ad.get("address").flatMap(_.asInstanceOf[Option[String]]),
        phonenumber = ad.get("phonenumber").flatMap(_.asInstanceOf[Option[String]]),
        email = ad.get("email").flatMap(_.asInstanceOf[Option[String]]),
        hours = hoursFromInput.fromResult(ad("hours").asInstanceOf[Seq[hoursFromInput.marshaller.Node]])
      )
    }
  }
}

FromInput[BusinessHoursInput] BusinessHoursInput .
