Here is the code 

  has_attached_file :image,
                        :path => ":rails_root/public/images/:id/:filename",
                        :url  => "/images/:id/:filename",
                        :styles => { :small => "300x168>", :large => "1000x560>" }

Here is my console log

检查您的图像魔法是否正确安装，因为调整大小取决于图像魔法。

一口气刷新所有定义的样式（上例中的：thumb、:small、:medium）

rake paperclip:refresh CLASS=Modelname

并且只刷新缺失的样式：样式列表将在文件“/public/system/paperclip_attachments.yml”中定义或更新</p> 

rake paperclip:refresh:missing_styles

此外，如果您只想重新处理一种样式，您可以这样做：

users_to_reprocess.each do |user|
  user.image.reprocess! :small
end

您可以在模型中使用:stylesgem paperclip。喜欢，

has_attached_file :photo,
  :styles => {
    :thumb=> "100x100#",
    :small  => "150x150>",
    :medium => "300x300>",
    :large =>   "400x400>" }

您的照片网址将如下所示：/public/photos/(event#)/(size_name)/image_name

你必须安装ImageMagick和rb-magick移植才能做到这一点。
