6.9. Summary

In this chapter you added a few features to the basic application, and the powerful concept of nested resources was introduced. Also introduced were two fundamental concepts: logging and debugging, which will serve you well as your journey toward learning Rails progresses.

The next three chapters cover the ActiveRecord framework, ActionController, and ActionView. You'll do a bit more incremental development on The Rails Noob blog here and there, but the main focus will be on introducing new concepts and reinforcing the existing ones, as opposed to performing major changes to the sample application that you have created so far.
