What do I need to do to upgrade an application to the latest Rails version?

Question

I am currently using Rails 2.1.0 and want to upgrade to Rails 2.1.1. After issuing the following command

gem update rails

I suppose that I need to change this line

RAILS_GEM_VERSION = '2.1.0' unless defined? RAILS_GEM_VERSION

in environment.rb

What other actions should I take to ensure that my application is using the latest version? Are there some other files that need an update?

Answer 1

You'll also need to go into your application directory and run the following command:

rake rails:update

Then run your tests and make sure everything works.
