Type Members

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

   

   A DAO implementation that operates on JSONCollection using JsObject.

   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")
