Standard practice for spray and casbah

[Dinesh Maske]

I am new in spray.

I am using spray 1.3 with mongodb database.

For mongodb i use casbah driver.

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)

}

I use above object for making connection to mongodb.

def insert(user: User) = {

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

}  

And this is my Repository class.

Is this implementation is correct? Or I need to change this according to spray for performance?

Please suggest me.
