rails 3.2.9 jquery_ujs不使用link_to

Question

我至少有以下不起作用的链接

= link_to 'Delete', admin_picture_comment_path(comment.picture_id,comment.id), :class => 'delete', :remote => true ,:method => :delete

= link_to 'Disable', set_shown_admin_picture_path(picture), :class => 'delete', :method => :put, :remote => true

= link_to 'show', set_show_admin_picture_path(picture), :class => 'delete', :method => :put, :remote => true

= link_to 'delete', admin_picture_path(picture), :confirm => 'Are you sure?', :class => 'delete', :method => :delete, :remote => true

正在创建的HTML看起来正确

<a href="/admin/pictures/27/comments/25" class="delete" data-method="delete" data-remote="true" rel="nofollow">Delete</a>

<a href="/admin/pictures/27/set_shown" class="delete" data-method="put" data-remote="true" rel="nofollow">Disable</a>

在所有情况下，我都会找回类似

的内容

没有路线匹配 [GET] “/ admin / pictures / 27 / comments / 23”

我认为这是因为jquery_ujs没有正确加载，但是我不知道为什么它没有加载，因为它显示在html标题中

<script src="/assets/jquery.js?body=1" type="text/javascript"></script>
<script src="/assets/jquery_ujs.js?body=1" type="text/javascript"></script>
<script src="/assets/jquery.fileupload.js?body=1" type="text/javascript"></script>
<script src="/assets/jquery.fileupload-ui.js?body=1" type="text/javascript"></script>
<script src="/assets/jquery.lightbox.js?body=1" type="text/javascript"></script>
<script src="/assets/application.js?body=1" type="text/javascript"></script>

的routes.rb

namespace :admin do
  #...
  resources :pictures do # admin/pictures
    member do
      put 'set_show'     
      put 'set_shown'
    end
    resources :comments, :only => [:destroy]
  end
end

application.html.haml

%html
  %head
    %title title
    = stylesheet_link_tag :application
    = javascript_include_tag :application
    = csrf_meta_tag

的application.js

//= require jquery
//= require jquery_ujs
//= require jquery.fileupload
//= require jquery.fileupload-ui
//= require jquery.lightbox

$(function(){

  $('.admin_picture a.delete').live('ajax:success',function(){
    $(this).closest('.admin_picture').fadeOut();
  });

  $('tr .ajax_delete').live('ajax:success', function() {
    $(this).closest('tr').fadeOut();
  });

  $('.comment a.delete').live('ajax:success',function(){
    $(this).closest('.comment').slideUp();
  });

  //...

});

的Gemfile

gem 'rails', '3.2.9'
gem 'thin'
gem 'jquery-rails'
gem 'haml-rails'   
#...

我从使用不显眼的jquery的rails 3.0应用程序升级时遇到了这个错误，我可能会错过什么会导致这种情况。

具体来说，我的jquery_ujs文件很旧并且仍然“存在”我的assets / javascript目录中。它仍然有不推荐使用的.live方法。删除文件!!
保持宝石'jquery-rails'，'〜＆gt; 2.1'＃REF：https://github.com/rails/jquery-ujs 保持// = require jquery和// = require jquery_ujs和// = require_tree。 在您的application.js文件中 确保更新gem和bundle install以获取最新的gem。 如果抛出javascript错误，就像我的“偷偷摸摸”的情况一样，其余的link_to js将无效。
