Uable to access nested json field about json-logic-scala

[grzegorz-taramina]

Hey @celadari,
Thanks for the reply.
I've managed to solve this issue overriding deserializeValueLogic function (Deserializer) like that:

`override protected[this] def deserializeValueLogic(jsonLogic: JsObject, jsonLogicData: JsObject): ValueLogic[_] = {
val isTypeDefined = (jsonLogic \ "type").isDefined
val typeValueOpt = Deserializer.unmarshType(jsonLogic \ "type")
val pathData = (jsonLogic \ "var").as[String]
val split = pathData.split("\.")

val lookUpPathData = if (split.isEmpty) {
  jsonLogicData \ pathData
} else {
  split.tail.foldLeft(jsonLogicData \ split.head)((b, a) => {
    b \ a
  })
}
val jsValue = lookUpPathData.getOrElse(JsNull)

if (isTypeDefined && lookUpPathData.isEmpty) {
  throw new InvalidJsonParsingException(s"""Error while parsing ValueLogic of type value: "var" $pathData is undefined""")
}
if (!isTypeDefined && lookUpPathData.isDefined) {
  throw new InvalidJsonParsingException(
    """Error while parsing ValueLogic of type variable: "var" must not be a key on data dictionary.""" +
      s"""\nActual: "$pathData"""")
}

val valueOpt = typeValueOpt.flatMap(typeValue => Option(getUnmarshaller(typeValue).unmarshal(jsValue)))
val variableNameOpt = if (lookUpPathData.isDefined) None else Some(pathData)
val pathDataOpt = if (lookUpPathData.isDefined) Some(pathData) else None

ValueLogic(valueOpt, typeValueOpt, variableNameOpt, pathDataOpt)

}`

Maybe it's worth adding that to the library as usual scenario for using jsonlogic is passing complex objects to jsonlogic engine.

Clever move, I will check if adding this line doesn't break unit and functional tests.

I'll let you know :)

Hello @grzegorz-taramina ,

Sorry for the late reply (I was afk for the last two weeks).

Current version do not accept accessing in nested data object. This can be added.

Is one of these alternatives what you're looking for:

• put every field at root level (I think this is not what you're looking for)
• define a type Booking (`case class Booking(ref){def } {def $less(num: java.lang.Integer): java.lang.Boolean = ref < num}' )

If not what you're looking for, we can see how to add the nested data structure field accessing

Hey @celadari,
Any update on this enhancement ?
