我有以下表格：

= 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'

当我单击保存按钮时，我可以在服务器日志中看到以下内容：

这意味着表单被提交了两次。我已经从我的公共目录中删除了 assets 文件夹。我还检查了页面上呈现的 html，并且没有双重包含 jquery 或其他依赖项。

为什么要提交两次？

我已经运行了 rake assets:precompile 并在开发模式下运行我的服务器。解决方案是 rake assets:clean 并重新启动服务器

我的解决方法：

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

rake 后，移除线路from app/assets/javascripts/application.js并启动服务器。现在它应该按预期工作。
