How do you ignore fields when serializing a case class using lift-json

Question

I have an example case class Child and I want to serialize it to JSON and print to the screen. This works fine but I don't want to serialize all of the fields, I want to ignore the name field but I can't figure out how. I have tried the following but no luck:

object test extends App{

  case class Child(id: Int, name: String, address: String)
  val simon = Child(1, "Simon", "Fake street")

  implicit val formats: AnyRef with Formats = DefaultFormats + FieldSerializer[Child](ignore("name"))

  val output = write(simon)
  println(output)
}

The above prints out the whole object but I want to print everything except the name field:

{"id":1,"name":"Simon","address":"Fake street"}
