I have the following overloaded functions to match my routes file
def getMessage() = getMessage(None, None, None)
def getMessage(campaignID: Option[String]) = getMessage(campaignID, None, None)
def getMessage(campaignID: Option[String], revision: Option[Int]) = getMessage(campaignID, revision, None)
def getMessage(campaignID: Option[String], revision: Option[Int], transactionID: Option[Int] ) = Action.async { implicit request =>
db.getDocument(campaignID, revision, transactionID)
.map(result =>
Ok(Json.toJson(result))).recover {case ex: IOException => InternalServerError("Please install MongoDB")}
}
Here's my routes file:
GET /message controllers.Application.getMessage()
GET /message/:campaignID controllers.Application.getMessage(campaignID:String)
GET /message/:campaignID/:revision controllers.Application.getMessage(campaignID:String, revision:Int)
GET /message/:campaignID/:revision/:transactionID controllers.Application.getMessage(campaignID:String, revision:Int, transactionID:Int)
How do I make it work so that campaignID, revision and transactionID are completely optional on the REST call? Right now, I am receiving the following error:
[error] /Users/superman/conf/routes:9: Compilation error[Using different overloaded methods is not allowed. If you are using a single method in combination with default parameters, make sure you declare them all explicitly.]

You need only a single method in your controller, like this:
package controllers
import play.api.mvc._
class Application extends Controller {
def options(id:Long, revision: Int, transaction: Int) = Action {
Ok(views.html.index(s"id: $id, revision: $revision, transaction: $transaction"))
}
}
And then you can declare your routes like this:
GET /options controllers.Application.options(id:Long = 1, revision:Int = 2, transaction:Int = 3)
GET /options/:id controllers.Application.options(id:Long, revision:Int = 2, transaction:Int = 3)
GET /options/:id/:revision controllers.Application.options(id:Long, revision:Int, transaction:Int = 3)
GET /options/:id/:revision/:transaction controllers.Application.options(id:Long, revision:Int, transaction:Int)
