Scala save future value to variable - scala

Question

my function to insert person:
def InsertPerson = Action(BodyParsers.parse.json) { request =>
val b = request.body.validate[Person]
b.fold(
//errorForm => Future.successful(Ok(views.html.index(errorForm, Seq.empty[User]))),
errors => {
BadRequest(Json.obj("status" -> "error", "message" -> JsError.toJson(errors)))
},
person => {
val f = ApplTagService.insertPerson(person)
f.map(res => "User successfully added").recover {
case ex: Error => ex.getMessage
}
f onFailure {
case t => println("An error has occured: " + t.getMessage)
}
Ok(Json.obj("status" -> f.toString() ))
})}
I send Json from CI to scala for insert person, then I want to give an alert if that insert is success or not, I need to save ex.getMessage or t.getMessage on a variable and send it to CI
what I get now on f.toString() in CI is scala.concurrent.impl.Promise$DefaultPromise#793e6657
How can I show ex.getMessage or t.getMessage in CI?

You can use Action.async(BodyParsers.parse.json) instead of Action(BodyParsers.parse.json) when you want to return a Future[Result] instead of a Result
In this case your match will look like this
b.fold(
errors => Future.successful(BadRequest(Json.obj("status" -> "error", "message" -> JsError.toJson(errors)))),
person => {
val f = ApplTagService.insertPerson(person)
val fMessage = f.map(res => "User successfully added").recover {
case ex: Error => ex.getMessage
}
f onFailure {
case t => println("An error has occured: " + t.getMessage)
}
fMessage.map(message => Ok(Json.obj("status" -> message )))
})
