形式提交两次：远程=>真正的Rails 3.2

我有以下形式：形式提交两次：远程=>真正的Rails 3.2

= form_for([current_user,@company], :remote => true) do |f| 
    -if @company.errors.any? 
    #error_explanation 
     %h2= "#{pluralize(@company.errors.count, "error")} prohibited this company from being saved:" 
     %ul 
     - @company.errors.full_messages.each do |msg| 
      %li= msg 
    =f.label :name 
    =f.text_field :name 
    =f.label :address 
    =f.text_area :address, :rows => 3, :cols => 5 
    =f.label :phone_number 
    =f.text_field :phone_number 
    .actions 
    = f.submit 'Save'

当我点击保存按钮，我可以看到我的服务器日志中folllowing：

这意味着表单正在提交两次。我已从我的公共目录中删除资产文件夹。我也检查了页面上呈现的HTML，并没有包含jquery或其他依赖关系。

为什么提交两次？

我曾运行过rake资源：预编译并在开发模式下运行我的服务器。解决办法是耙资产：干净，然后重新启动服务器

我对这种解决方法：

rake assets:precompile 
with //= require jquery_ujs in your app/assets/javascripts/application.js

耙后，取出线from app/assets/javascripts/application.js并启动服务器。现在它应该按预期工作。
