render partial在控制台中不显示任何错误

我正在尝试在我的页面上呈现一个分部。控制台或终端日志中没有错误，场景是。。。用户选择页面上的链接，并且中间区域应该呈现。我通过jquery运行它，并让提交进入我的控制器"会话"和方法"showsurvey"，它获得必要的信息，然后渲染到showsurvey.js.erb，用showsurveypartial 替换html

这是涉及的代码。。。。显示newuser.html.erb

        <%= include_gon %>

<div id="content" class="clearfix">

<%= render :partial => 'layouts/user_profile' %>
      <div class="inner">
        <div class="top_area">          
          </div> <!-- top_area -->               
          <p>Welcome <%=@user.email%> Drag the topics into the order of importance to you.</p>
           <div id="middle_area" > 
            <%= render :partial => 'middle_newuser' %>
      <div id="find">
         <p>Where voters and politicians can discuss and learn  about the issues for free with no advertising dollars getting in the way <br />
         Subscribe to RSS feeds to stay in touch with their latest votes. </p>
      </div>
</div>   <!-- inner_area -->

替换_middle_newuser.html.erb 的原始分部

              <div id = "draggable" class="ui-widget-content">
        <h3 class="ui-widget-header">Issues</h3>
         <table>
         <tr><td>
        <ul id ="column1" >
        <% (0..5).each do |i| %>
         <% @sm_pic= @cat[i][:small_pic] 
            @CatName = @cat[i][:name] 
            @id = @cat[i][:id]%>
               <li id="draggable">
            <%= link_to image_tag(@sm_pic, :border => 0), showsurvey_path({:data => @id}), :remote => true, :data => @id , :id => 'showSurvey'  %>
          </li> 
         <% end %>  
        </ul>
          </td>
                   <td>
           <ul id ="column1"  >
           <% (6..11).each do |i| %>
           <% @sm_pic= @cat[i][:small_pic] 
            @CatName = @cat[i][:name] 
            @id = @cat[i][:id]%>
                <li id="draggable">
            <%= link_to image_tag(@sm_pic, :border => 0), showsurvey_path, :data => @id %>
                         </li>
              <% end %>
        </ul>
         </td>
           <td>
         <ul id ="column1"  >  
         <% (12..17).each do |i| %>
         <% @sm_pic= @cat[i][:small_pic] 
            @CatName = @cat[i][:name] 
            @id = @cat[i][:id]%>
               <li id="draggable">
            <%= link_to image_tag(@sm_pic, :border => 0), showsurvey_path, :data => @id %>
              </li>
         <% end %>
          </ul>
             </td></tr>
         </table>
         </div id>  <!-- draggable -->
           </div>  <!-- middle_area -->

以及应该取代它的部分_middle_survey.html.erb

             <div>
         <table><tr>
           <div id="middle_area-left" >
           <p>Welcome this will be the survey page for user after clicking on a priority icon.</p>
           </div>
           <div id="middle_area-center" >
           <%= render :partial => 'form' %>
           </div>
           <div id="middle_area-right" >
           <p>Welcome this will be the survey page for user after clicking on a priority icon.</p>
           </div>
           </tr>
           </table>
           </div>

控制器方法为showSurvey

  def showsurvey
  @title = "Survey for"
   @category = Category.find(params[:data])
       @questions = @category.questions.find_all_by_category_id(params[:data])
       @current_question_rec =  @questions.first
       @current_question = @current_question_rec.question
       @current_question_id = @current_question_rec.question_id
       @answer = @category.questions.find(@current_question_id).answers.find_by_user_id(params[:id])
   respond_to do |format|
     format.html { redirect_to @category }
         format.js { render }
 end           

end

最后一次显示Survey.js.erb

$(#middle_area').replace_html( "<%= escape_javascript render :partial => "middle_survey" %> ");

还有一件事是我的终端的输出

Processing by SessionsController#showsurvey as JS

  Category Load (0.2ms)  SELECT "categories".* FROM "categories" WHERE "categories"."id" = ? LIMIT 1  [["id", "3"]]
