我正在尝试将我的Play框架应用程序从光滑迁移到SORM。创建了基本类，但无法使其正常工作。
case class UserAction(url: String, request: Map[String,String], ts: DateTime)
val ts = DateTime.now()
val act = Db.save(UserAction(request.uri, request.headers.toSimpleMap, ts))
但是得到以下异常：
play.api.Application$$anon$1: Execution exception[[ClassCastException: __wrapper$1$cf01f4410488416a9990d12622889a84.__wrapper$1$cf01f4410488416a9990d12622889a84$PersistedAnonymous31$1 cannot be cast to models.sorm.UserAction]]

我做错了什么？
