crypt：路由中的basename

Question

我正在使用回形针并以下列方式将路径网址设为

has_attached_file :avatar,
  :path => ":rails_root/app/assets/images/:basename.:extension"

问题是我需要加密basename属性，okey rails有一个函数crypt，但是如何将它用于路由，如下所示：

has_attached_file :avatar,
  :path => ":rails_root/app/assets/images/#{:basename.crypt('key')}.:extension"

Answer 1

看看是否有效

has_attached_file :avatar,
  :path => ":rails_root/app/assets/images/#{Paperclip::Interpolations.basename.crypt('key')}.:extension"
