How to replace a JSON value in Play

Question

How do I replace a value in a JSON value in Play?
Code to illustrate:

def newReport() = Action(parse.json) { request =>
    var json = request.bod         


        

Answer 1

a glorified version of Zeimyth's answer that uses implicit conversion

implicit class JsObjectEnhancer(jsObject: JsObject) {
  def update(args: (String, Json.JsValueWrapper)*): JsObject = {
    jsObject ++ Json.obj(args: _*)
  }
}

usage (json must be of type JsObject and the implicit class should be in scope)

json.update("customerId", 1000)
