Rails 3 is the newest version of Rails, and it comes with significantly more flexibility than previous versions of Rails. If you want to continue using Rails the way you’ve always used it, the strong system of conventions and defaults that Rails has become known for are still the golden path moving forward. But if you want to plug in alternatives to Rails’ conventions or hook directly into parts of the internals, Rails 3 provides a power-users’ API that will be supported and maintained moving forward. Yehuda will walk you through the principles of that API, show you how to read and understand the Rails source code so you can customize the framework just the way you want.
