Scalaz's Applicative Functor for Futures.
// Zip together a couple Futures, including one that returns an Option
// and pass them to a function to give me a new object:
api.channels.tree zip api.pages.getByRoute(route) map {
case (tree, Some(page)) => Some(new PagePresenter(context, tree, page))
case _ => None
}
// Now with an Applicative Functor!
(api.channels.tree |@| api.pages.getByRoute(route)) {

When receiving a multipart POST, parse the application/json part into an entity, and capture the file upload.
pathEndOrSingleSlash {
(post & parameter("rev")) { rev =>
// This is very important, so we can provide a more specific
// implicit to overcome the Json4sSupport default unmarshaller

sam / FunctionalComposition.scala
Created September 5, 2013 15:43
Simple example of a Play Framework / ScalaTest spec using functional composition to keep the building of two similar Requests (only difference is the Request-Method) DRY.
"Delete" taggedAs(tag.RolesTag) in {
val request = (FakeRequest(_:String, "/admin/roles/role-bob")) andThen
withAdminCredentials andThen
(route(_:FakeRequest[AnyContentAsEmpty.type]))
for { result <- request(DELETE) } {
status(result) must equal(SEE_OTHER)
flash(result).data must contain key("deleted")
}

Last active August 26, 2016 22:04
A trivial, common example and for-comprehensions failing at it.
// fold
client ! Projects(rows.headOption.fold(Nil)(_ \ "value" extract))
// map.getOrElse
client ! Projects(rows.headOption
.map(_ \ "value" extract)
.getOrElse(Nil))
// Option.toList
client ! Projects(rows.headOption.toList.map(_ \ "value" extract))

There's got to be a better way...

Example of a json4s Format for a sealed trait (Id) with two implementations (NewId or IdWithRev).
import org.json4s._
case object IdSerializer extends CustomSerializer[Id](formats => ( {
case JObject(JField("prefix", JString(prefix)) :: JField("id", JString(id)) :: JField("rev", JString(rev)) :: Nil) => IdWithRev(prefix, id, rev)
case JObject(JField("prefix", JString(prefix)) :: JField("id", JString(id)) :: Nil) => NewId(prefix, id)
}, {
case NewId(prefix, id) => JObject(JField("prefix", JString(prefix)) :: JField("id", JString(id)) :: Nil)
case IdWithRev(prefix, id, rev) => JObject(JField("prefix", JString(prefix)) :: JField("id", JString(id)) :: JField("rev", JString(rev)) :: Nil)
}
))
