Base Class properties not written to MongoDB

Using Play 2 / Scala , casbah and Salat

abstract class BaseQuestion(val data:String,val responses:List[StudentResponse] = Nil){
  val key:String = UUID.randomUUID().toString
}

case class Question(override val data:String, val questionType:String = "MCQ", val choices:List[String] = Nil,
                    val answer:String,override val responses:List[StudentResponse])
  extends BaseQuestion(data = data,responses = responses)

However when I use SalatDAO.save, and check the mongo database the property key is not being stored in the Mongo database Object.

Not sure what the problem is.

Thank you in advance.

Solution

  • You need to annotate property key with @Persist
