如何使用paperclip

如何使用paperclip-googledrive从谷歌驱动器下载文件？(How to download file from google drive using paperclip-googledrive?)

我已经完成文件上传谷歌驱动器，但在下载时出现错误：

ActionController::MissingFile: Cannot read file original_22_Wages372-817339(wages).pdf

我认为它没有得到谷歌驱动器的路径。

附件型号：

has_attached_file :doc, storage: :google_drive, google_drive_credentials: "#{Rails.root}/config/google_drive.yml", google_drive_options: { public_folder_id: '0BwCp_aK6VhiaQmh5TG9Qbm0zcDQ', path: proc { |style| "#{style}_#{id}_#{doc.original_filename}" } }

控制器：

attachment = Attachment.find(params[:id]) send_file attachment.doc.path(:original), filename: attachment.doc_file_name, type: attachment.doc_content_type, stream: 'true', x_sendfile: true

提前致谢

I have done file uploading on google drive but at the time of downloading got error:

ActionController::MissingFile: Cannot read file original_22_Wages372-817339(wages).pdf

I think it didn't get google drive path.

Attachment model:

has_attached_file :doc, storage: :google_drive, google_drive_credentials: "#{Rails.root}/config/google_drive.yml", google_drive_options: { public_folder_id: '0BwCp_aK6VhiaQmh5TG9Qbm0zcDQ', path: proc { |style| "#{style}_#{id}_#{doc.original_filename}" } }

Controller:

attachment = Attachment.find(params[:id]) send_file attachment.doc.path(:original), filename: attachment.doc_file_name, type: attachment.doc_content_type, stream: 'true', x_sendfile: true

Thanks in advance
