Question

I am looking to create a file uploader using Ruby on Rails that must have the following features :

• Work for any file type
• Get upload progress
  • I used an apache module to track progress but flash solutions are acceptable
• Use Amazon S3 as the filesystem
  • Rails creates a RackMultipart file in the tmp folder that needs to be moved to S3 wondering is there is a better way
• Extremely reliable
  • My current implementation occasionally either fails to track progress properly or sometimes the RackMultipart file isn’t created (Rails 2.3.8)

My system is Rails 2.3.8, Ruby 1.8.7 Enterprise, Apache.

I’ve tried all of these and have had a problem with each one:

AFAIK it’s not even good practice do upload like this. Upload and use delayed job to handle it in the background `workers’ are supposed to do this on heroku.
