#Dr StrangeCode or "How I Learned to Stop Worrying and Love the Rails 3.0 Upgrade"* I recently upgraded one of my Rails applications from 2.3.5 to 3.0.0 (and from ruby 1.8.7 to 1.9.2). I took a series of notes of all the problems and issues I ran into. ##Ruby 1.8.7 to 1.9.2 upgrade
- FasterCSV is part of 1.9.2, but not 1.8.7. If you want to maintain compatibility with both, then keep using FasterCSV.
- ftools no longer exists in ruby 1.9.2. Was using it in a require. I just used fileutils instead.
- I had a bunch of old-style case/when statements that no longer work in 1.9.
