We’ve just posted our seventh screencast, the 15th lesson in the Learning Rails series. In this screencast, we add the concept of subpages, so we can have pages that don’t appear in the main navigation but instead show up as second-level navigation links on their parent page. To do so, we use a self-referential has_many association.

There’s lots more than can be done to continue refining our little content management system, but it’s rapidly approaching a useful level for small sites. We’ll wrap up some loose ends in the next screencast, and then move on in future screencasts to take care of the Contact Us and Resources pages. Then we plan to circle back and fix up the tests.

We’re thrilled to see that several thousand people are following the screencasts, and that the comments we’ve received have been overwhelmingly positive. If you’d like to help spread the word, pick up our Learning Rails ad and include it on your blog.
