Mongodb 如何使用Rogue对日期字段进行排序？

-

无工作-这是错误消息

  def findAllSortByDateThisGivesAnError: List[Trade] = Trade
    .orderAsc(_.trade_date)
    .fetch()

Rogue不太支持

日历

字段。如果可以，使用

DateField

或

DateTimeField

，它们由

java.util.Date

支持，这与其说是一个答案，不如说是一个指向任何与Rogue和日期搏斗的人的指针——当某件事情不起作用时，将其作为DateTime并将其传递给Rogue；当它返回时，您可能必须将其从java.util.Date中拖出并返回到Joda中

    override def displayName = "Begins"
}
