I'm in the process of trying to combine some nested calls with reactivemongo in my play2 application.
I get a list of objects returned from createObjects
. I then loop over them, check if the object exist in the collection and if not insert them:
def dostuff() = Action {
implicit request =>
form.bindFromRequest.fold(
errors => BadRequest(views.html.invite(errors)),
form => {
val objectsReadyForSave = createObjects(form.companyId, form.companyName, sms_pattern.findAllIn(form.phoneNumbers).toSet)
Async {
for(object <- objectsReadyForSave) {
collection.find(BSONDocument("cId" -> object.get.cId,"userId" ->
object.userId.get)).cursor.headOption.map { maybeFound =>
maybeFound.map { found =>
Logger.info("Found record, do not insert")
} getOrElse {
collection.insert(object)
}
}
}
Future(Ok(views.html.invite(form)))
}
})
}
I feel that this way is not as good as it can be and feels not "play2" and "reactivemongo". So my question is: How should I structure my nested calls to get the result I want and get the information of which objects that have been inserted?
