Question

这是代码

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

这是我的控制台日志

我需要将小型，大型和原始图像存储到我的项目公共目录中，但它只存储原始

Answer 1

检查您的图像magick是否正确安装，因为调整大小取决于图像magick。

一次性刷新所有已定义的样式（：thumb，：small，：来自上例的中等）

rake paperclip:refresh CLASS=Modelname

并仅刷新缺少的样式：将在文件“/public/system/paperclip_attachments.yml”中定义或更新样式列表

rake paperclip:refresh:missing_styles

此外，如果您只想重新处理单一样式，可以这样做：

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

Answer 2

您可以在模型中使用:styles paperclip个宝石。像，

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

您的照片网址如下：/public/photos/(event#)/(size_name)/image_name

您必须安装ImageMagick和rb-magick端口才能实现此目的。
