Paperclip不使用自定义路径保存图像

Question

我尝试使用自定义路径通过paperclip保存图片，但它不起作用。

图像记录是在数据库中创建的，但在system/web/message_attachments/images/000/000中没有任何内容。

在我的message_attachment模型中：

has_attached_file :image, styles: { original: ['1920x1920>', :jpg],
                                    medium:   ['640x640>',   :jpg]
}, path: "web/message_attachments/images/:id/:timestamp_to_i.:style.:extension"

Paperclip.interpolates :timestamp_to_i do |attachment, _|
  attachment.instance_read(:updated_at).to_i
end

在我的rails日志中：
