all models need to be case classes for salat to work.

A simple model

package models

import play.api.Play.current
import java.util.{Date}
import com.novus.salat._
import com.mongodb.casbah.Imports._
import se.radley.plugin.mongodb._
import se.radley.plugin.mongodb.salat._

case class User(
  id: ObjectId = new ObjectId,
  username: String,
  password: String,
  address: Option[Address] = None,
  added: Date = new Date(),
  updated: Option[Date] = None,
  @Key("company_id")company: Option[ObjectId] = None
)

case class Address(
  street: String,
  zip: String,
  country: String
)

object User extends SalatDAO[User, ObjectId](collection = getCollection("users")) {
  def all = find(MongoDBObject())
  def findOneByUsername(username: String): Option[User] = findOne(MongoDBObject("username" -> username))
  def findByCountry(country: String) = find(MongoDBObject("address.country" -> country)).toList
}

The imports are important :P

• import com.novus.salat._ makes all the salat stuff work
• import com.mongodb.casbah.Imports._ makes all the implicit convertions between the mongodb javadriver and scala work
• import se.radley.plugin.mongodb._ makes getCollection() available
• import se.radley.plugin.mongodb.salat._ and most important of all this one import the salat context

I've choosen to have the DAO in the companion object, but some may say that you should separate the repository logic, in that case your could simply rename it to UserDAO or UserRepository

If you would like to connect another source specify it as the second parameter to getCollection

object User extends SalatDAO[User, ObjectId](collection = getCollection("users", "myothersource")) {

and make sure you've added it to your application.conf

CRUD

the SalatDAO class contains all the logic for saving, updating, removing entities.

User.save(User(username = "leon", password = "1234"))
