二极管。向电路发送多个动作

  • 772

同事们，我不知道如何从diode. 这是一段代码App Circuit：

val handler = new ActionHandler(myZoomedState) {
    override def handle = {
      case action => effectOnly(Effect(someFuture map {_ =>
        someAction  //Этот экшен не отрабатывает
        someOtherAction  //Этот отрабатывает
      }))

      case someAction => ???
      case someOtherAction => ???
    }
}

怎么把它们锁起来？类似于我们对回调所做的事情：
someCallback >> someOtherCallback

    解决方案是创建结合这两个动作的第三个动作。此外，它不会破坏未来的错误处理。看起来像这样：

    case object DoSmthStuff
...

val handler = new ActionHandler(myZoomedState) {
    override def handle = {
      case action => effectOnly(Effect(
          someFuture map { _ => DoSmthStuff } recover { ... }
      ))

      case DoSmthStuff = effectOnly(
          Effect.action(someAction) >> Effect.action(someOtherAction)
      )

      case someAction => ???
      case someOtherAction => ???
    }
}
