Enhance the ability to create writes and reads from complex case classes graph.
Add into your build.sbt the following lines:
resolvers += "null-vector" at "https://nullvector.jfrog.io/artifactory/releases" libraryDependencies += "null-vector" %% "play-json-mapping" % "<version>"
This example use the same model using in play-json examples:
import play.api.libs.json._ import org.nullvector.JsonMapper._ case class Location(lat: Double, long: Double) case class Resident(name: String, age: Int, role: Option[String]) case class Place(name: String, centerLocation: Location, residents: Seq[Resident]) implicit val w: Writes[Place] = writesOf[Place] implicit val r: Reads[Place] = readsOf[Place] //or just: implicit val m: Format[Place] = mappingOf[Place]
And use as follow:
val place = Place( "Watership Down", Location(51.235685, -1.309197), Seq( Resident("Fiver", 4, None), Resident("Bigwig", 6, Some("Owsla")) ) ) val json: JsValue = place.asJson
Scala Enumerations are also automatic mapping:
case class Money(amount: BigDecimal, currency: Money.Currency) object Money extends Enumeration { type Currency = Value val ARS, BRL, USD, MXN = Value } ... implicit val moneyMapping: Format[Money] = JsonMapper.mappingOf[Money]
