has_attached_file :attachment,:url  =>           ":rails_root/public/photos/images/:id/:style/:basename.:extension",:default =>        ":rails_root/public/images/no-image-available.png",:styles =>          style_options,:default_style =>   :gallery

和style_options是@H_403_5@

style_options = {  :thumbnail => {:geometry => '100x100'},:profile_gallery =>  {:geometry => '184x247'}
                  }

在我的公共文件夹中创建3个文件夹,同时一个图像上传1.缩略图,2.profile_gallary 3.原始.@H_403_5@

在我的视图文件中,我打电话@H_403_5@

<%= photo.thumbnail_url %>

我的问题是我想使用上传图片的原始路径.我不想将thumnail用于任何特定网址.我怎样才能使用原始路径.@H_403_5@

感谢Advance@H_403_5@
