Getting Rails 3.0-beta running on Heroku

I wanted to test out Rails 3.0-beta and see how far I could get with developing an application with my stack of gems/plugins. I hadn’t checked out Heroku either, so it gave me an opportunity to try out their new stacks with Ruby 1.9.1.

First, I installed Rails 3 Beta and RVM outlined in Ryan Bate’s screencast. If you haven’t installed RVM yet, you will be wondering why it’s taken you this long. I did.

Once you have Rails up and running, you can following with their quick start guide. There’s a couple of things to take note when deploying for Rails 3.0-beta, but it’s all pretty straight forward.

As mentioned in the documentation you will need to add the “pg” gem to your Gemfile as Heroku runs Postgres database on their servers; i.e. not MySQL.

  # Gemfile
  group :production do
    gem "pg" 
  end  

By placing it in the “production” group you won’t need to install it locally.

I’m super impressed by Heroku, and look forward to get a production application running on their platform. It’s simply awesome.
