We are in the process of upgrading a very large Rails 2 app to Rails 3. I decided that this would be an excellent time to actually update this blog! So, I'm going to try to post a quick blurb every time I run into a gotcha that bites me. Here is the first one:
Switching to the mysql2 gem to use with Rails 3, got it included in your gemfile, still won't work?
Make sure you change your adapter: settings in your database.yml to "mysql2".
