    You can provide an implementation of QueryStringBindable[A] for any type A you want to be able to bind directly from the request query string.

    For example, if you have the following type to encode pagination:

    /**
     * @param index Current page index
     * @param size Number of items in a page
     */
    case class Pager(index: Int, size: Int)

    Play will create a Pager(5, 42) value from a query string looking like /foo?p.index=5&p.size=42 if you define an instance of QueryStringBindable[Pager] available in the implicit scope.

    For example:

    object Pager {
      implicit def queryStringBinder(implicit intBinder: QueryStringBindable[Int]) = new QueryStringBindable[Pager] {
        override def bind(key: String, params: Map[String, Seq[String]]): Option[Either[String, Pager]] = {
          for {
            index <- intBinder.bind(key + ".index", params)
            size <- intBinder.bind(key + ".size", params)
          } yield {
            (index, size) match {
              case (Right(index), Right(size)) => Right(Pager(index, size))
              case _ => Left("Unable to bind a Pager")
            }
          }
        }
        override def unbind(key: String, pager: Pager): String = {
          intBinder.unbind(key + ".index", pager.index) + "&" + intBinder.unbind(key + ".size", pager.size)
        }
      }
    }

    To use it in a route, just write a type annotation aside the parameter you want to bind:

    GET  /foo        controllers.foo(p: Pager)
