Inheritance Lift映射程序或记录框架中的继承

是否有一种方法可以使用Mapper o Record Framework在Lift中定义适当的继承模型，其中父类有一个表，每个子类有一个表？

假设您希望使用继承来在每个子类中使用相同的映射字段，我已经通过为这些字段使用特征来实现这一点：

trait SuperFields[T <: Mapper[T]] {
  self: T =>
  object DESCRIPTION extends MappedString[T](this, 255)
  object BRAND extends MappedString[T](this, 50)
  // etc
}

以及：

class Product extends Mapper[Product] with SuperFields[Product] {
  override def getSingleton = Product
}

object Product extends Product with MetaMapper[Product] {
  override def dbTableName = "PRODUCT"
  override def dbDefaultConnectionIdentifier = SomeConnection
}

class Service extends Mapper[Service] with SuperFields[Service] {
  override def getSingleton = Service
}

object Service extends Service with MetaMapper[Service] {
  override def dbTableName = "SERVICE"
  override def dbDefaultConnectionIdentifier = SomeOtherConnection
}
