Rails 3.0: Agnosticism

When Rails and Merb merged, agnosticism was one of the big features to be added to Rails. They have stayed true to this vision.

Take a look at the help when creating a new Rails application.

rails new --help

You will notice three options.

• -O: Skip Active Record
• -T: Skip Test::Unit
• -J: Skip Prototype

This allows you to create a fresh Rails application and have it ready to integrate with other gems more easily.

rails new myproject -OTJ
