榆树郎将列表中的元素到父容器

Question

我有以下类型的模型：

type alias NetworkList = 
    { networks : (List Network) } 

type alias Network = 
    { name: String } 

一旦我加载它们，我要显示在取景功能的UL列表。我发现这种解决方案通过每个孩子在列表进行迭代：

networkPickContent: NetworkList -> Html Msg 
networkPickContent networks = 
    networks 
     |> List.map networkRow 
     |> ul [ class "my_class" ] 


networkRow: Network -> Html Msg 
networkRow network = 
    li [] [ text network.name ] 

却无法真正使工作，调试器返回错误：

The right side of (|>) is causing a type mismatch. 

    networks 
     |> List.map networkRow 

(|>) is expecting the right side to be a: 

    NetworkList -> a 

But the right side is: 

    List Network -> List (Html Msg) 

我在做什么错在这案件？为了这种目的使用List.map是否合理？还是有更好的方法来显示所有的子元素？

NetworkList是以网络作为关键字的记录。尝试以下代替

networkPickContent: NetworkList -> Html Msg 
networkPickContent networkList = 
    networkList.networks 
     |> List.map networkRow 
     |> ul [ class "my_class" ]
