How to insert JSON documents in Mongodb using Play/Scala ?

[Aravind M]

Hi all, I am trying to upload/insert json object/document from my front-end to store in Reactivemongo database(2.6) using Play/Scala framework(2.2.3). I have done the following trails, but I am failing to insert json document in the database. 

class Application extends Controller with MongoController {

def jsinfocollection: JSONCollection = db.collection[JSONCollection]("mycollection")

def createJson = Action.async(parse.json) {

    request =>

        request.body.validate[JsValue].map {

println("calling: request.body.validate..!!")//coming message on Play console

        jsoninfo =>

          jsinfocollection.insert(jsoninfo).map {

  println("calling: jsinfocollection.insert..!!")//coming message on Play console

            lastError =>//Error is showing on Play console: play - Cannot invoke the action, eventually got an error: play.api.libs.json.JsResultException: JsResultException(errors:List((,List(ValidationError(errir.expected.jsobject,WrappedArray())))))]]

              logger.debug("Json data inserted Successfully in Mongodb collection with LastError: $lastError")

              Created("JsonInfo is Saved")

          }

      }.getOrElse(Future.successful(BadRequest("invalid json data")))

  }

}

I created a collection,called: "mycollection" in Mongodb already like: >db.createCollection("mycollection")

{ "ok" : 1 }

but if I give: >db.mycollection.count() - is giving 0, otherwise if I give: db.mycollection.find() - is giving nothing

routes:

POST /createJson controllers.Application.createJson

Error:

POST http://localhost:9000/createJson 500 (Internal Server Error)

play - Cannot invoke the action, eventually got an error: play.api.libs.json.JsResultException: JsResultException(errors:List((,List(ValidationError(errir.expected.jsobject,WrappedArray())))))]]

Please help me regarding this where and what I am doing wrong to upload/insert my json data into my required collection("mycollection") ?

I guess the question has already been posted on StackOverflow (BTW please avoid duplicate questions).

As said, you would get more support using recent versions, Play 2.2 is quite old.

Hi Cédric Chantepie, 

yes, but my application requires 2.2.3 version only. May I know anything where I am doing wrong ?
