import play.api.libs.functional.syntax._

case class User(id: Long, name: String, friends: Seq[User] = Seq.empty)
object User {

  // In this format, an undefined friends property is mapped to an empty list
  implicit val format: Format[User] = (
    (__ \ "id").format[Long] and
    (__ \ "name").format[String] and
    (__ \ "friends").lazyFormatNullable(implicitly[Format[Seq[User]]])
      .inmap[Seq[User]](_ getOrElse Seq.empty, Some(_))
  )(User.apply, unlift(User.unapply))
}

object MyController extends play.api.mvc.Controller {

Abstract Value Members

abstract def maxPlain: BigDecimal
Maximum magnitude of BigDecimal to write out as a plain string.
Maximum magnitude of BigDecimal to write out as a plain string. Defaults to JsonConfig.defaultMaxPlain. This can be set using the JsonConfig.maxPlainProperty system property.
abstract def minPlain: BigDecimal
Minimum magnitude of BigDecimal to write out as a plain string.
Minimum magnitude of BigDecimal to write out as a plain string. Defaults to JsonConfig.defaultMinPlain. This can be set using the JsonConfig.minPlainProperty system property.
abstract def preserveZeroDecimal: Boolean
True to preserve a zero decimal , or false to drop them (the default).
True to preserve a zero decimal , or false to drop them (the default). For example, 1.00 will be serialized as 1 if false or 1.0 if true (only a single zero is preserved). Other trailing zeroes will be dropped regardless of this value. For example, 1.1000 will always be serialized as 1.1. This can be set using the JsonConfig.preserveZeroDecimalProperty system property.
