在项目Gemfile中增加一下代码:
gem 'ckeditor', '3.5.4' 

#安装插件     
bundle install     
#生成ckeditor的js文件,查看config/initializers/ckeditor.rb     
#获取更多的配置信息     
rails generate ckeditor:base     
#生成上传图片的类     
#For attachment_fu:      
rails generate ckeditor:migration --backend=attachment_fu    
#For paperclip:     
rails generate ckeditor:migration --backend=paperclip    
#执行migration，生成数据库表     
rake db:migrate     
#在application.rb增加以下内容     
config.autoload_paths += %W( #{config.root}/app/models/ckeditor )  

#引用js文件  
<%= javascript_include_tag :ckeditor %>  
#创建输入框的普通helper方法  
<%= ckeditor_textarea("object", "field", :width => '100%', :height => '200px') %>
