Ruby on rails rails部分错误-未找到路由

当我在没有AJAX的情况下渲染这个部分时，它工作得很好，但是当我使用AJAX调用渲染它时，我得到了以下异常

我做错了什么

ActionView::Template::Error (No route matches {:action=>"destroy", :followerid=>1,     :follower_type=>"topic", :controller=>"follows", :discussion_id=>91}):
2: <% discussion.followers.each do |topic| %>
3:     <% if topic.is_a? Topic%>
4:           <h3><%= render :partial => '/shared/topic_item', :locals => { :topic => topic }%></h3>
5:           <%= button_to("unTag", discussion_follow_path(discussion.id, :follower_type => "topic", :followerid => topic.id ), :method => :delete, :remote =>true) %>
6:     <%end%>
7: <%end%>

您是否在路由文件中添加了类似资源：主题的内容？是的。资源：主题做资源：如下，：only=>[：创建，：销毁]结束
