object Node {
  import Connector.db

  def apply(nid: Int): Option[Node] = {
    db withSession {
      val ntype = Query(NodeMap).filter(_.nid is nid).map(_.ntype).firstOption

      ntype.map { typestring =>
        typestring match {
          case "page" => new Page(nid)
          case "landing_pages" => new LandingPage(nid)
        }
      }
    }
  }
}

  val image = getImage
}
