They use FancyUploader (which uses MooTools/Flash) to upload directly to S3, bypassing Heroku and their dreaded 30 second request timeout all together, and then use DelayedJob to queue up post-processing tasks like thumbnailing and PaperClip to do the actual processing of the files.

他们使用FancyUploader(使用MooTools / Flash)直接上传到S3,绕过Heroku及其可怕的30秒请求超时,然后使用DelayedJob排队后处理任务,如缩略图和PaperClip来进行实际处理文件。

If I can get this working with CarrierWave, I will post up a project on GitHub to share (in a week or so once I get time)

如果我可以使用CarrierWave,我将在GitHub上发布一个项目进行分享(一旦我有时间,一周左右)

Update:

I will add the post-processing example once I have time.

我有时间后会添加后处理示例。

You can either create a processor or use the callback methods but the file will definitively be on your server before going to S3.

您可以创建处理器或使用回调方法,但在转到S3之前,文件最终会在您的服务器上。

If you are in the callback method for example you can access it using something like:

例如,如果您使用回调方法,则可以使用以下方法访问它:

self.file.to_file

Once that is done processing and uploading the file will be deleted from your server. You don't need to do anything to notify or post process. Paperclip will handle it.

完成后,处理和上传文件将从您的服务器中删除。您无需做任何事情来通知或发布流程。 Paperclip将处理它。
