val db = mongoClient("test") val coll = db("test") val q = MongoDBObject("id" -> 100) val result= coll.findOne(q)
How can I convert result to a map of key --> value pairs?
result
result of findOne is an Option[Map[String, AnyRef]] because MongoDBObject is a Map. A Map is already a collection of pairs. To print them, simply:
for { r <- result (key,value) <- r } yield println(key + " " + value.toString)
or
result.map(_.map({case (k,v) => println(k + " " + v)}))
To serialize mongo result, try com.mongodb.util.JSON.serialize, like
com.mongodb.util.JSON.serialize
com.mongodb.util.JSON.serialize(result.get)
