Vote_fu和Ajax请求

Question

我已经呆了好几个小时了，试着让vote_fu运行起来。我终于对一个可投票的对象(相册)进行了投票，但我必须不断刷新页面，以看到我的Ajax知识对于rails的影响是基本的，我不知道我在哪里出错了，任何帮助都会是非常好的！

有关守则如下：

javascript文件

application.js:

 // Place your application-specific JavaScript functions and classes here
 // This file is automatically included by javascript_include_tag :defaults

 jQuery.ajaxSetup({
 'beforeSend': function(xhr) {xhr.setRequestHeader("Accept", "text/javascript")}
 })

 jQuery(document).ready(function() {
 $("#votes_ .album").bind('click', function(e) 

 });

|___________________________________________________________________________________________

jquery.js jquery-ui.js jrails.js

布局/appliction.html.erb(将javascript添加到标头)

<%= javascript_include_tag :defaults %>
<%= javascript_include_tag 'jquery.js', 'application.js' %>

意见/投票

_album_vote.html.erb

<%# 
 # You can't vote if it is your quote, 
 # you are not logged in, 
 # or you have already voted on this item

 unless album.user == current_user ||
 current_user.voted_on?(@album)
%>

 <%= link_to_remote "Vote Up",
  :url => user_album_votes_path(album.user, album, :vote => :true, :format => :rjs),
  :method => :post %>




 <%= link_to_remote "Down", 
  #:url => current_user.vote_down_path(album), :vote => :false, :format => :rjs, 
  :url => user_album_votes_path(album.user, album, :vote => :false, :format => :rjs),
  :method => :post
  %> 

<%# end %>



Votes: <%= @album.votes_for - @album.votes_against %>

|___________________________________________________________________________________________

查看/相册/展示：

<div id="votes_<%= @album.id %>" class="album_votes">
 <%= render :partial => "votes/album_vote", :locals => {:album => @album} %>
</div>

|___________________________________________________________________________________________

create.rjs

page.replace_html "votes_#{@album.id}", :partial => "album_vote", :locals => {:album => @album}

|___________________________________________________________________________________________

error.rjs

page.alert "Couldn't save your vote: You can only vote once, and you cannot vote for your own items."

|___________________________________________________________________________________________

我试过使用ID #votes_ .album，我认为它的名称是错误的，但是它仍然不能工作，甚至一个错误都没有，就好像javascript关闭了一样！

任何帮助都会很好！

在服务器控制台上找到错误：

NameError (uninitialized constant Mime::RJS):
  app/controllers/votes_controller.rb:54:in `create'
  app/controllers/votes_controller.rb:52:in `create'

在灯亮(睡觉时间)之前，我会同意的！

如果你愿意的话，帮我一把！

看起来，您的基本jquery设置存在问题。以下两篇文章无疑帮助我提高了jQuery的学习曲线：

这些帖子和令人惊叹的FireBug应该能帮你达到目的

希望这能有所帮助。
