Question

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'

当我点击保存按钮时，我可以在服务器日志中看到以下内容：

这意味着表单正在提交两次。我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，并且没有包含jquery或其他依赖项的双重内容。

为什么要提交两次？

Answer 1

我运行了rake资产：预编译并在开发模式下运行我的服务器。解决方案是耙资产：清理并重新启动服务器

Answer 2

我的解决方法：

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

在rake之后，删除行from app/assets/javascripts/application.js并启动服务器。现在它应该按预期工作。

表格提交两次：remote =＆gt;真正的Rails 3.2
