Second session reviewed what has happened with Rails since 1.0. Plugins, migrations, RJS, etc. This was just what I needed because I tend to code in the 1.0 mode. It was also a review of upcoming sessions. So as the sessions continue I'm create a list of "better or required practices" that I'll post after the conference.
Instead of dinner last night I replace some "has_and_belongs_to_many" with "has_many .. :through =>". Made a few errors, but I learned. This turned out to be the perfect solution for a problem I was having.
