Question

不知何故，编辑后的更新方法是将id传递为“show”

这里是我“更新”\

时传递的参数

我的表单是新主人（和作品）的相同形式：

<%=form_for @owner , remote: true do |f| %>

    <div class="modal-body">
    <div class="row">

        <div>

            <div class="col-md-6" style="float: right">

        <%#= f.hidden_field :owner_id, { :value => @owner.id } %>

                <%= f.label 'שם לקוח', class:"control-label" %>
                <%= f.text_field :name, class: "form-control" %>
                </div>

                <div class="form-group">

                <%= link_to "Cancel", "#", class: "btn", data: {dismiss: "modal"} %>

update.html.erb呈现相同的save.js.erb，它在创建新所有者时可以找到。

Answer 1

在rails中创建RESTful路由的首选方法是使用资源：

resources :owners

哪个会给你GET /owners/:id这是一个规范的Rails REST路由，它指向OwnersController上的show动作。

不要创建以下路线：

/owners/show
/owners/index
/owners/create

除非你想看起来不称职。在Rails中，操作由所使用的HTTP谓词和最后存在的动态ID段推断。

请参阅：

Rails Routing from the Outside In

Answer 2

发布问题后3秒，我在路线文件中找到了这个：

  get 'owners/show'#, as: :owner

并将其更改为

  get 'owners/show'

看起来我不需要那个别名。
