1.下载fckeditor_plugin-0.3.2.zip，目前版本为0.3.22.解压到vendor\plugins目录下，并且重新命名为fckeditor3.到该应用程序根目录下，然后运行rake fckeditor:install，则执行自动安装4.在自己的view层中添加<%= javascript_include_tag :fckeditor %>以及在你需要编辑的字段textarea替换为<%= fckeditor_textarea("book", "desc", { :toolbarKit => 'Simple', :width => '100%', :height => '200px' }) %>第一个参数为你的domain对象，desc为你的编辑字段值，其他顾名思义然后运行你的页面程序，发现simple upload有点bug，上传后javascript报错5.追踪代码发现vendor\plugins\fckeditor\app\controllers\fckeditor_controller.rb下的500)this.width=500'> def upload500)this.width=500'> self.upload_file500)this.width=500'> end调用了upload_file方法500)this.width=500'>def upload_file500)this.width=500'> @new_file = params[:NewFile]500)this.width=500'> @url = upload_directory_path500)this.width=500'> begin500)this.width=500'> ftype = @new_file.content_type.strip500)this.width=500'> if !
