Rails 3 is now beta and the core team is asking people to try it out and report issues back. We decided to do a small spike to get some experience with the upgrade process and see if we could help identify any problems. The application we worked on was our own Pivotal Pulse CI aggregation display (which you can see in action).
Here's a quick overview of the steps we went through:
- Install Ruby 1.8.7 using RVM
- Install Rails beta gems
- Upgrade the app using the rails_upgrade plugin
- Tweak things a lot
- Drop incompatible dependencies
- Profit!
