A simple battery of scripts for upgrading Rails app/checking them for required updates. This application should work on Rails 2.x and 3.0, with a focus on upgrading to 3.0.
You need to install this plugin first:
script/plugin install git://github.com/rails/rails_upgrade.git
Then you can run its rake tasks to check your application:
# Check your app for required upgrades rake rails:upgrade:check # Backup your likely modified files that might be overwritten by the generator rake rails:upgrade:backup # Generate a new route file rake rails:upgrade:routes # Generate a Gemfile from your config.gem directives rake rails:upgrade:gems # Generate code for a new config/application.rb from your environment.rb rake rails:upgrade:configuration
