I have a case class like this:
case class Admin(name: String, role: Role)
Role
is an Enumeration
object Role extends Enumeration {
type Role = Value
val Manager = Value
}
When I try to:
import io.circe.generic.auto._, io.circe.syntax._
val response = Admin("John", Role.Manager).asJson.noSpaces
I get the implicit Encoder not found error.
not enough arguments for method asJson: (implicit encoder: io.circe.Encoder[Admin])io.circe.Json. Unspecified value parameter encoder.
I suppose this error is due Enumeration, so I changed to:
trait Role
object Role {
object Manager extends Role
}
But this does't work too.
Lastly, I tried:
trait Role
object Manager extends Role
And no success. Can someone help me please? Thanks!
enumeratum-circe enables the following syntax
object CirceEnumeratumExample extends App {
import enumeratum._
import io.circe.generic.auto._, io.circe.syntax._
sealed trait Role extends EnumEntry
case object Role extends Enum[Role] with CirceEnum[Role] {
case object Manager extends Role
case object User extends Role
val values = findValues
}
case class Admin(name: String, role: Role)
val response = Admin("John", Role.Manager).asJson.noSpaces
println(response)
}
which outputs
{"name":"John","role":"Manager"}
where
libraryDependencies += "com.beachape" %% "enumeratum" % "1.5.13",
libraryDependencies += "com.beachape" %% "enumeratum-circe" % "1.5.21"
