avoiding null values in asJson method

[Mohsen Jamali]

One of the fields in my case class is an option (e.g. case class Person(name:String,gender:Option[String]) ). I want a way that when 'gender' is None, the method person.asJson does not contain gender:null in it, but just have one attribute in it (the name attribute).

Thanks!

Please paste some code so that we can see how you are currently doing this.

You're most likely looking for the `:=?` operator for building up the json, based on a codec.
