I have 3 futures of type Response. The first future returns a JsValue which defines if future 2 and future 3 shall be executed or only future 3 shall be executed.
Pseudocode: If Future 1 then {future2 and future 3} else future 3
Iam trying to do this in a play framwork action which means in order to use the result of the futures later I cant use onSuccess, onFailure and onComplete because all of them return Unit and not the actual JsValue from the last future.
I tried to do this with map() and andThen but I am a Scala noob and I guess i wasn't able to do it because I always just missed a little point. Here is my current approach which does not work!
def addSuggestion(indexName: String, suggestion: String) = Action.async {
val indexExistsQuery: IndexExistsQuery = new IndexExistsQuery(indexName);
val addSuggestionQuery: AddSuggestionQuery = new AddSuggestionQuery(indexName, suggestion)
val indexCreationQuery: CreateCompletionsFieldQuery = new CreateCompletionsFieldQuery(indexName)
val futureResponse: Future[Response] = for {
responseOne <- EsClient.execute(indexExistsQuery)
responseTwo <- EsClient.execute(indexCreationQuery) if (indexExistsQuery.getBooleanResult(indexExistsQuery.getResult(responseOne)))
responseThree <- EsClient.execute(addSuggestionQuery)
} yield responseThree
futureResponse.map { response =>
Ok("Feed title: " + (response.json))
}
