ActionController::InvalidAuthenticityToken解决办法

1、在Controller中加入
 class FooController < ApplicationController
    protect_from_forgery :except => :index

    # you can disable csrf protection on controller-by-controller basis:
    skip_before_filter :verify_authenticity_token
  end

2、修改配置文件config\environments\development.rb

 # Disable request forgery protection in development environment
   config.action_controller.allow_forgery_protection = false
3、在jquery或form中加入

<%= tag(:input, :type => "hidden", :name =>
request_forgery_protection_token.to_s, :value =>
form_authenticity_token) %>
