Generic resource routes issues

[Ryan Proud]

I'm attempting to create a trait which will define a default set of routes given a path, but I'm running into an issue illegal inheritance issue.  I'm just wondering if there's a way around this.  It's basically my inexperience with Scala that is preventing me from seeing a solution, or lack of one.  Any help would be appreciated.

trait DefaultResourceRoutes[M <: Serializable] {
  this: HttpService with Actor =>

  def resourceRoutes(resourceName: String)(implicit um: FromRequestUnmarshaller[M]) = path(resourceName) {
    get {
      complete(s"$resourceName-getAll")
    } ~
    post {
      entity(as[M]) { entity =>
        complete(s"$resourceName-create")
      }
    } ~
      patch {
        entity(as[M]) { entity =>
          complete(s"$resourceName-update")
        }
      }
  } ~
    path(resourceName / LongNumber) { entityId =>
      get {
        complete(s"$resourceName-get")
      }
    } ~
    path(resourceName / "name" / Segment) { namePattern =>
      get {
        complete(s"$resourceName-getByName")
      }
    }
}

object Boot extends App {

  implicit val system = ActorSystem("API")

  /* Use Akka to create our Spray Service */
  val router= system.actorOf(Props[Router], "api-router")

  /* and bind to Akka's I/O interface */
  IO(Http) ! Http.Bind(router, "0.0.0.0", 8888)
}

class Router extends HttpServiceActor with ApiService with ActorLogging {
  def receive = runRoute(fooRoutes ~ barRoutes)
}

trait ApiService extends HttpService with FooService with BarService

trait FooService extends HttpService with Actor with DefaultResourceRoutes[Foo] {
  import Json4sProtocol._
  def fooRoutes = resourceRoutes("foo")
}

trait BarService extends HttpService with Actor with DefaultResourceRoutes[Bar] {
  import Json4sProtocol._
  def barRoutes = resourceRoutes("bar")
}

object Json4sProtocol extends Json4sSupport {
  override implicit def json4sFormats: Formats = DefaultFormats
}
