find with reactive mongo and play framework

I want to retrieve a user's data by his mail from MongoDB using ReactiveMongo driver for play framework but it returns: Future(<not completed>)

Here is my code:

def findBymail(email: String) = {
  val query = Json.obj("mail" -> email)
  val resul = collection.flatMap(_.find(query).one[Users])
  Logger.warn(s"result found: $res") 
}

All operations in ReactiveMongo is async, it always returns Future, So you can print the result with

collection.flatMap(_.find(query).one[Users]).map{ u => Logger.warn(s"result found: $res")

I think this may not you want, you can return the Future as well, and handle the result, 

def findBymail(email: String) = {
  val query = Json.obj("mail" -> email)
  collection.flatMap(_.find(query).one[Users]).map{ user =>
      Logger.warn(s"result found: $user") 
      user
  }
}

You can handle the result as:

findBymail("....").map{ user =>
    ......
}
