Spray Form Data to Case Class

Question

New to Scala to go easy on me!

I'm using spray atm and posting requests in. I'm looking to convert the post data to a case class but it throws an error could not find implicit value for parameter um: spray.httpx.unmarshalling.FromRequestUnmarshaller. What might I be doing incorrect? The Documentation is a bit confusing.

post {
    entity(as[TextMessage]) { txt =>
        println(txt.body)
        complete("")
    }
}

And my Case Class case class TextMessage( body: String, from: String)

From the docs this should work off the bat.

Ideas?

Edit: The data isn't being posted as JSON it's posted as form data i.e. application/x-www-form-urlencoded

Make sure that the JsonFormat for the TextMessage type is in the scope, so that Spray cand find out how to marshall that type.

I haven't parsed form data with spray so I don't know if easier way exists but I would use formFields directive.

val textMessageEntity = formFields('body, 'from).as(TextMessage)

post {
    textMessageEntity { txt =>
        println(txt.body)
        complete("")
    }
}

Here is more information about formFields directive: http://spray.io/documentation/1.2.2/spray-routing/form-field-directives/formFields/
