Paperclip无法访问上传文件

Question

我有以下型号：

has_paper_trail                              # Track model with paper_trail
has_attached_file :image, :styles => { :medium => "300x300>"}, 
  :path => ":rails_root/public/attachments/:project_id/ressources/:id_:basename_:style.:extension",
  :url  => ":rails_root/public/attachments/:project_id/ressources/:id_:basename_:style.:extension"

belongs_to :project

# convert :project_id in path to project_:project_id
Paperclip.interpolates :project_id do |attachment, style|
  "project_#{attachment.instance.project_id}"
end

它有效，但当我想在我的视图中显示图像时，它找不到图像，我该如何解决？

Answer 1

替换

解决

:url  => ":rails_root/public/attachments/:project_id/ressources/:id_:basename_:style.:extension"

通过

:url  => "/attachments/:project_id/ressources/:id_:basename_:style.:extension"
