reactivemongo

Hey im pretty new to Spray and reactive mongo . Im trying to return a list of result as json but i'm having some issue with converting the result to list of json. this is my model import reactivemongo.bson.BSONDocumentReader import reactivemongo.bson.BSONObjectID import reactivemongo.bson.Macros case class Post(id: BSONObjectID, likes: Long, message: String, object_id: String, shares: Long) object Post { implicit val reader: BSONDocumentReader[Post] = Macros.reader[Post] } the Mongo method def getAll(): Future[List[Post]] ={ val query = BSONDocument( "likes" -> BSONDocument( "$gt" -> 27))

I'm writing a Play/Scala application using Play 2.5.4 and ReactiveMongo. Based on this example , I'm getting the collection using class SettingStore( val mongo:ReactiveMongoApi) { def collection = mongo.db.collection[BSONCollection]("Settings") // more code... } However, db is now deprecated. The deprecation warning recommends I use database , but this one returns a Future so all operations have to be mapped over. Since ReactiveMongo's operations also return Future s, this seems redundant... what's to proper way of getting a collection? (or, am I missing something completely and Future[Future

I defined BSONDocumentWriter s to map domain objects (case classes) to BSON documents to be persisted in MongoDB using the ReactiveMongo driver. Defining the writers is quite straight-forward for case classes (although tedious and error prone: I wish there was a Salat-like solution for that). However, I can't seem to be able to do the same for a Map[String,Any] (where the values can be of type numeric, date or string). I found a code example that defines a generic writer (and reader) for a map: implicit def MapWriter[V](implicit vw: BSONDocumentWriter[V]): BSONDocumentWriter[Map[String, V]] =

I have a collection in my MongoDB database with say several keys. Now I want to update this collection with a new field. So here is what I have so far: def confirm(hash: String) = { val myDb = dbConn.db(dbName) val userCollection = myDb[BSONCollection]("user") val selector = BSONDocument(idKey -> BSONObjectID(hash)) val modifier = BSONDocument( "$set" -> BSONDocument("date" -> BSONString(now.toString)) // Line 1 ) val command = FindAndModify( userCollection.name, selector, Update(modifier, fetchNewObject = true) ) myDb.command(command) .map { user => // Line 2 Right(bidList) }.recover { case

I am trying to do some tests using ScalaTest + embedmongo + reactivemongo but I fail. My first problem is that after a test mongod process does not shut down, I have this message in console: INFO: stopOrDestroyProcess: process has not exited and tests are paused till I kill the process manually. That happens even if body of my test is empty. I am running windows 8.1. The other issue is, that when I try to connect to db inside test using reactive mongo and insert anything to db I get this exception: reactivemongo.core.errors.ConnectionNotInitialized: MongoError['Connection is missing metadata
