We want to implement a progress bar for file uploading in one of our Ruby application. This needs to show the exact percentage of the upload. However, despite our best efforts we could not find a way to implement a progress bar that exactly replicate the file upload process.
Can you please help us with this?
If your are using Apache and Passenger, you can use the Apache progress bar module.

I have used mongrel_upload_progress in the past, but I found that it was quite a complex and delicate solution to the problem. I'd definitly recommend looking towards using passenger thru apache for your production environment, though.
