The best way to learn Ruby on Rails also happens to be a fast way. Check out these links to get you on your way.
Ruby on Rails Guides – Official
• Hands down best resource. Everything basic to get you into Rails is covered.
After you watch those there are a TON of Free Screencasts done at Railscasts that are all super short with real world examples of most things beginners strive to do in Rails:
• 5 View Tips
• Rails Forms Part 1, Part 2, Part 3
• Model Name in URL
• Nested Resources
• Subdomains and Routing
• Named Routes
• Custom Routes
• Paperclip – attaching photos to models
• Integrating with Active Merchant
• Polymorphic Associations
• YAML Configuration Files
• Cron in Ruby
Function lookup and API
There are two good ways to use the api to learn what functions and classes you have to work with. I like the first way best cause it’s a little more searchable even though it takes a little longer to load:
• Ruby on Rails API Easy Search and Example Interface – Make sure you use Rails 2
• RailsBrain API Search Interface
• Official Ruby on Rails API – Harder to navigate
Ruby Cheat Sheet to answer very basic syntax question
How to send an email in Rails – Who doesn’t need to know this? Nobody.

Great Resource for displaying Rails dates in the view or form selectors
Handling Sub-folders RESTfully
Getting started with RESTful Rails
Rails and MacOSX
Good read. Starting about halfway through is where it gets useful really: Developing Rails Apps on a Mac
Using YAML Files
I should use more YAML Configuration files for sure. As should you.
