Play Framework: How to serialize/deserialize an enumeration to/from JSON
implicit val genderReads = Reads.enumNameReads(Gender) is working fine for me. Play Scala 2.4.2
Try changing it to
def reads(json: JsValue) = JsSuccess(MyEnum.withName(json.as[String].value))
Expanding on @surenyonjan's response, the following works nicely with Play Json 2.6:
object MyEnum extends Enumeration { type MyEnum = Value val e1, e2 = Value implicit val myEnumReads = Reads.enumNameReads(MyEnum) implicit val myEnumWrites = Writes.enumNameWrites}
