JsonDao

abstract class JsonDao[Model, ID] extends Dao[JSONCollection, JsObject, Model, ID, Writes]

A DAO implementation that operates on JSONCollection using JsObject.

To create a DAO for a concrete model extend this class.

Below is a sample model.

import reactivemongo.bson.BSONObjectID
import play.api.libs.json.Json
import play.modules.reactivemongo.json.BSONFormats._

case class Person(
  _id: BSONObjectID = BSONObjectID.generate,
  name: String,
  surname: String,
  age: Int)

object Person {
  implicit val personFormat = Json.format[Person]
}

To define a JsonDao for the Person model you just need to extend JsonDao.

import reactivemongo.api.{ MongoDriver, DB }
import reactivemongo.bson.BSONObjectID
import play.modules.reactivemongo.json.BSONFormats._
import reactivemongo.extensions.json.dao.JsonDao
import scala.concurrent.ExecutionContext.Implicits.global


object MongoContext {
 val driver = new MongoDriver
 val connection = driver.connection(List("localhost"))
 def db(): DB = connection("reactivemongo-extensions")
}

object PersonDao extends JsonDao[Person, BSONObjectID](MongoContext.db, "persons")
Model

Type of the model that this DAO uses.

ID

Type of the ID field of the model.
