After uploading a file to your server/database you may want users to download it, and send_file works great for just that! Lets say you are allowing users to upload "gif" files to your /RAILS_ROOT/images/*usern ame*/*thegif.gif*. Now you want to allow them to download them or other users to download the pictures.

Ruby on Rails on Oracle: A Simple Tutorial
This article is not intended to be a booster piece for Rails nor is it an expose. It’s simply an introduction to the technology. It contains both praise and criticism. At times the criticism might appear a bit heavy handed (especially to Rails enthusiasts), but don’t be fooled. Using any Web application framework is going to be tricky, whether it’s J2EE, ASP.NET, or PHP. In the long run, you can be a lot more productive with Rails than you can be with many other Web application development platforms, but it takes time to learn the ropes.
