Insert with unique indexes, Salat + Casbah

[zaid emeish]

Greetings,

I am using Salat and Casbah to create a user collection in Mongodb, everything works great until I added a unique index on the email field. Now my insert returns a unique id with no actual record added in the DB for existing email addresses. I am new to scala and Casbah/Salat so I apologize if I am asking an obvious question.

here are my collection indexes

db.users.getIndexes()

[

{

"v" : 1,

"key" : {

"_id" : 1

},

"name" : "_id_",

"ns" : "study_test.users"

},

{

"v" : 1,

"unique" : true,

"key" : {

"email" : 1

},

"name" : "users_email",

"ns" : "study_test.users"

}

]

and this is my dao object

object UserDao extends SalatDAO[UserModel, ObjectId](collection = MongoUtil.getCollection("study", "users")) {

  val logger = LoggerFactory.getLogger(UserDao.getClass)

  val dao = this

  UserDao.collection.ensureIndex(DBObject("email" -> 1), "users_email", true)

  RegisterJodaTimeConversionHelpers()

  def create(userContract: UserContract): Option[ObjectId] = {

    val userModel = UserConverter.toModel(userContract)

    dao.insert(userModel)

  }

and this is the unit test I am running

class User extends Specification{

  val logger = LoggerFactory.getLogger("User Test")

  sequential

  "Insert test" should {

    "create new User collection" in {

      val user = UserContract("John", "Doe", "joh...@domain.com", "08/14/1982", "test", "male")

      val id = Try(UserDao.create(user)).toOption.flatten

      logger.debug("id was " + id)

      id must not equalTo None

    }

  }

}

I found what the problem was, I upgraded mongodb and casbah 2.10 but used MongoConnection to connect to mongoDB. I switched to connection using mongo client and all works as expected.
