PlayEnum

An Enum that has a lot of the Play-related implicits built-in so you can avoid boilerplate.

Note, the binders created here are case-sensitive.

Things included are:

implicit JSON format
implicit PathBindable (for binding from request path)
implicit QueryStringBindable (for binding from query strings)
formField for doing things like Form("hello" -> MyEnum.formField)

Example:

scala> import enumeratum._
scala> import play.api.data.Form
scala> import play.api.libs.json._

scala> sealed trait Greeting extends EnumEntry

scala> object Greeting extends PlayEnum[Greeting] {
     |   val values = findValues
     |   case object Hello   extends Greeting
     |   case object GoodBye extends Greeting
     |   case object Hi      extends Greeting
     |   case object Bye     extends Greeting
     | }

scala> val form = Form("greeting" -> Greeting.formField)
scala> form.bind(Map("greeting" -> "Hello")).value
res0: Option[Greeting] = Some(Hello)

scala> Json.toJson(Greeting.Hello) res1: JsValue = "Hello"
