javascript - Rails 4 JQuery Ajax 未显示

Question

我创建的 thing 对象没有显示在使用 jQuery/Ajax 的 View 中。

我想在此处附加到 div 标记的内容索引.html.erb

<h1>Listing things</h1>
<%= link_to 'New Thing', new_thing_path, id: "new_thing_link", remote: true %><br>

    <% @things.each do |thing| %>
      <div class="things">
        <%= thing.user_name %>
        <%= thing.topic %>
        <%= thing.truth %>

        <%= link_to 'Show', thing %>
        <%= link_to 'Edit', edit_thing_path(thing) %>
        <%= link_to 'Destroy', thing, method: :delete, data: { confirm: 'Are you sure?' } %><br><br>
      </div>    
    <% end %>
<br>

因此，在 Controller 中，我让 js 格式响应此自定义模板。前 2 个步骤按预期工作，我从服务器输出中得到 200 OK。

创建.js.erb

$(".actions").remove(); // remove the form
$("#new_thing_link").show(); //show the new link again
$('.things').append('<%= j render @thing %>'); //insert the new task into the index template

_create.html.erb

<tr id="topics">
    <td><%= thing.user_name %> |</td>
    <td><%= thing.topic %> |</td>
    <td><%= thing.truth %></td>
</tr>

things_controller.rb

def create
    @thing = Thing.new(thing_params)

    respond_to do |format|
      if @thing.save
        format.html { redirect_to things_url, notice: 'your posting was added.' }
        format.js 
      else
        format.html { render :new }
        format.json { render json: @thing.errors, status: :unprocessable_entity }
      end
    end
  end

但是新的 div 仅在我刷新页面时才会显示。当我在不刷新页面的情况下查看源代码并且控制台没有显示任何错误时，它就在那里。

这是服务器输出，因此我知道正在创建记录，

  Rendered things/create.js.erb (2.2ms)

View 没有按我的预期更新。我究竟做错了什么？这是涡轮链接问题吗？

看起来您的使用方式正确。尝试这个小更改，指定您的部分位置(请注意，您的部分路径可能是错误的，因为我不知道您如何组织事物):

$('.things').append("<%= j render :partial => 'things/create', :locals => {:thing => @thing} %>");
