Standard practice for spray and casbah connection

[Dinesh Maske]

I am new in Spray.

I am using spray 1.3 with mongoDb database.

For mongodb connection i use Casbah Driver.

Following is my Connection object

import com.mongodb.casbah.{MongoClient, MongoCollection, MongoConnection}
import config.Configuration

object MongoFactory extends Configuration{

  private val USERS = "users"

  val mongoClient = MongoClient(mongodbHost, mongodbPort)
  val db = mongoClient(mongodbName)
  val USER_COLLECTION = db(USERS)

}

This object is used for connection to mongodb.

def create(user: User) = {

val doc = UserMongoMap.toBson(user)
MongoFactory.USER_COLLECTION.insert(doc)

}

This is my repository class method

Is this implementation is correct? OR i need changes according to spray for better performance?
