如何在elm中发送消息(无事件)

我正在努力学习Elm,并一直在努力找出构建可扩展应用程序的最佳方法。关于布线,我想有一些简单的逻辑,根据电流呈现各种视图 route Players 视图,我只想在从服务器收到一些数据时渲染它。如果请求挂起或失败,我想显示一个错误页面。我意识到我可以在 视图,但我更愿意向模型发送一条消息,以将路由更改为另一个视图。我只知道如何发送事件消息( onClick 等)。这是可能的还是我在语言设计之外工作?

Nothing ->
    notFoundView

发送更改路由的消息

view : Model -> Html Msg
view model =
    div []
        [ page model
        ]

page : Model -> Html Msg
page model =
    case model.route of
        PlayersRoute ->
            listView model.playersModel.players

        PlayerRoute id ->
            editView model id

        NotFoundRoute ->
            notFoundView

玩家视图

editView : Model -> PlayerId -> Html Msg
editView model id =
    case model.playersModel.players of
        NotAsked ->
            text ""

        Loading ->
            text "Loading ..."

        Failure err ->
            text (toString err)

        Success players ->
            let
                maybePlayer =
                    players
                        |> List.filter(\player -> player.id == id)
                        |> List.head
            in
                case maybePlayer of
                    Just player ->
                        core player

                    Nothing ->
                        notFoundView
