Upgrading to Rails 2.1 RC1 (with HAML)

May 31st, 2008 — HAML, Rails

Good morning one and all. Here is a step-by-step transcript of how I got my project from Rails 2.0.2 to 2.1 RC1.

1. Remove Rails 2.0.2 from the project and the svn repo:

[-]View Code BASH
svn rm vendor/rails
svn commit vendor/rails -m "[REMOVED] Rails 2.0.2 from repo;"

2. Checkout Rails 2.1 RC1 from the git repository, and then move to the 2.1 RC1 branch:

[-]View Code BASH
cd vendor
git clone git://github.com/rails/rails.git
cd rails
git checkout v2.1.0_RC1

3. Start the server:

I’m using HAML, so I got this error:

[-]View Code BASH
=> Booting Mongrel (use 'script/server webrick' to force WEBrick)
=> Rails application starting on http://0.0.0.0:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server

A quick search on google, led me to this post: http://nex-3.com/posts/76-haml-2-0

So, I proceeded to update to HAML 2. Here goes:

sudo gem update

It updated quite a few gems, and yes, one of them was indeed HAML 2.0.

4. Start server, take 2
No errors!! You should now be running on Rails 2.1 RC1. Congratulations.

5. Commit to svn:

svn add vendor/rails
svn commit vendor/rails -m "[UPDATED] app to Rails 2.1 RC1"
