Scala override error - scala

Question

I am using Play framework 2.2.x and SecureSocial and for testing I am trying to override a method in a superclass. Actually I am getting a compile error using the test helper classes from secure social and I can not figure it out as I am not all that familiar with Scala.
What I don't understand is why my ide things the method is correctly overridden but when I compile I get the error. I know scala is not that well integrated with the ides but I can not see why the override is incorrect.
/**
* This is the secure social class and method I am trying to override.
I have left the other methods out for clarity. The problem method is the doAuth method
**/
package securesocial.core
import providers.utils.RoutesHelper
import play.api.mvc.{SimpleResult, AnyContent, Request}
import play.api.{Play, Application, Plugin}
import concurrent.{Await, Future}
import play.api.libs.ws.Response
abstract class IdentityProvider(application: Application) extends Plugin with Registrable {
/**
* Subclasses need to implement the authentication logic. This method needs to return
* a User object that then gets passed to the fillProfile method
*
* #param request
* #return Either a Result or a User
* This is the method I am having trouble trying to override
*/
def doAuth()(implicit request: Request[AnyContent]):Either[SimpleResult, SocialUser]
}
This is the my class and the doAuth() override
package testkit
import play.api.Logger
import securesocial.core._
import play.api.mvc.{Result, Request}
import securesocial.core.IdentityId
class AlwaysValidIdentityProvider(app:play.api.Application) extends IdentityProvider(app){
val logger = Logger("securesocial.stubs.AlwaysValidIdentityProvider")
def authMethod: AuthenticationMethod = AuthenticationMethod("naive")
override def doAuth()(implicit request: Request[play.api.mvc.AnyContent]): Either[Result, SocialUser] ={
val userId = request.body.toString
val r =Right(SocialUserGenerator.socialUserGen(IdentityId(userId, id), authMethod).sample.get)
r
}
def fillProfile(user: SocialUser): SocialUser = {
user
}
def id: String = "naive"
}
The error I am getting is: As you can see it thinks I am overriding nothing.
[error] /Users/zola/Development/play/receipt-manager/rm-play/test/testkit/AlwaysValidIdentityProvider.scala:8: class AlwaysValidIdentityProvider needs to be abstract, since method doAuth in class IdentityProvider of type [A]()(implicit request: play.api.mvc.Request[A])Either[play.api.mvc.Result,securesocial.core.SocialUser] is not defined

Answer 1

That's because the method you are overriding is not already defined. You have a signature in the abstract class and that's it.
Try this instead:
def doAuth()(implicit request: Request[play.api.mvc.AnyContent]): Either[Result, SocialUser] ={
val userId = request.body.toString
val r =Right(SocialUserGenerator.socialUserGen(IdentityId(userId, id), authMethod).sample.get)
r
}

Answer 2

To solve the issue I looked at other classes within SecureSocial and they way they implemented the method was
def doAuth[A]()(implicit request: Request[A]): Either[Result, SocialUser] = {
val userId = request.body.toString
val r =Right(SocialUserGenerator.socialUserGen(IdentityId(userId, id), authMethod).sample.get)
r
}
