Rails 3: Getting started with user file uploads

I am new to Ruby on Rails. I'm creating an application that allows user generated content, including photo uploading. I have worked with file uploading in PHP开发者_如何转开发 applications, but since I'm new to Ruby and Rails, I was wondering if there is a common technique, plugin, or gem that makes managing file uploads really easy.

You need the Paperclip gem. Watch this awesome video from Ryan Bates over at RailsCasts.com then you'll be ready to rock. http://railscasts.com/episodes/134-paperclip

It's easy!
