Konrad, Thanks for the reply!
In fact I have the very same code separation:
*object ApiJsonProtocol extends ApiJsonProtocoltrait ApiJsonProtocol
extends SprayJsonSupport with DefaultJsonProtocol { implicit val
feedFormat = jsonFormat2(Feed) // implicit val feedsWriter =
seqFormat[Feed]}*
*class FeedRoute(feedRepository: FeedRepository) extends ApiRoute with
ApiJsonProtocol {*
* override val underlying: Route = {*
* pathPrefix("feeds") {*
*pathEndOrSingleSlash {*
*get {*
*parameters('from.as[Int] ? 0, 'limit.as[Int] ? 10, 'title ? "") { (from,
limit, title) =>*
*complete(*
*// TODO use (from, limit, title)*
*feedRepository.findAll()*
*)*
*}*
*}*
*}*
* }*
*}*
*}*
But without the extra "*implicit val feedsWriter = seqFormat[Feed]*" it
does not compile.
On GitHub I've found several examples of people trying to solve the same
problem:
1) Use of .toJson before wrapping into complete(...)
https://github.com/ArchDev/akka-http-rest/blob/master/src/main/scala/me/archdev/restapi/http/routes/UsersServiceRoute.scala
2) Declaring implicit val for each Seq[of somethings] but in this
particular case the author went further and coded full RootJsonWriter
https://github.com/dit4c/dit4c/blob/f66f833ef35d58234391e9e0f09ad36b7a4a6206/dit4c-machineshop/src/main/scala/dit4c/machineshop/ApiService.scala
So, it appears I'm not the only one who finds this a little bit confusing.
Regards,
Ilya
