How to implement a progress bar in Ruby?

Question

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.

People don't use Mongrel in Production anyway, you would probably end up using Nginx and Mongrel Clusters. In any case, I think there are plugins for Mongrel as well As Nginx. I haven't tried it using Mongrel but as always "Google is your friend" or try at the irc #rubyonrails

Sure people use Mongrel in production, if Apache or Nginx are overkill. It's about the right tool for the job and for low traffic sites, especially inside a firewall, Mongrel is fine.

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.
