Ruby On Rails:Ajax刷新部分不起作用

标签: ruby-on-rails ruby ajax

我很难在按下按钮时尝试刷新部分内容。我想简单地刷新div,而不是整个页面。以下是我在视图中的内容:

<div id="ajax">
  <%= render 'layouts/confessions' %>
</div>

然后在我的部分_confessions.html.erb中,我有一些基本的html和两个类似的按钮:

<%= form_tag( { :controller => :confessions, :action => :upvote, :id => conf.id }, { :method => :put } ) do %>
    <%= submit_tag 'Like' %>
<% end %>

我的confessions_controller.rb:

def upvote
  @confession = Confession.find(params[:id])    
  Confession.increment_counter :upvotes, @confession
  respond_to do |format|
    format.js
  end
end

最后,upvote.js.erb

$('#ajax').html("<%= escape_javascript(render(:partial => 'confessions')).html_safe %>");

提交到我的数据库的操作正在运行,但页面现在重定向到/upvote?id=9(id可能不同),而不是仅刷新div。我究竟做错了什么?我是Rails的新手,所以我可能会遗漏一些完全明显的东西......

编辑:这是我的文件夹结构:

我的观点:views/pages/home.html.erb

我的部分:views/layouts/_confessions.html.erb

我的控制器:controllers/confessions_controller.rb

我的js.erb文件:views/confessions/upvote.js.erb

rake routes之后

    confessions GET    /confessions(.:format)            confessions#index
                POST   /confessions(.:format)            confessions#create
new_confession  GET    /confessions/new(.:format)        confessions#new
edit_confession GET    /confessions/:id/edit(.:format)   confessions#edit
 confession     GET    /confessions/:id(.:format)        confessions#show
                PUT    /confessions/:id(.:format)        confessions#update
                DELETE /confessions/:id(.:format)        confessions#destroy
     upvote            /upvote(.:format)                 confessions#upvote
   downvote            /downvote(.:format)               confessions#downvote
       root            /                                 pages#home

确保在application.js

中有此功能
//= require jquery
//= require jquery_ujs

仅供参考:Rails form_for :remote=>true is not calling js method

然后,改变这个,

$('#ajax').html("<%= escape_javascript(render(:partial => 'confessions')).html_safe %>");

致:

$('#ajax').html("<%= escape_javascript(render(:partial => 'layouts/confessions')).html_safe %>");

添加:remote =&gt;真

<%= form_tag( { :controller => :confessions, :action => :upvote, :id => conf.id }, { :method => :put, :remote=>true } ) do %>
