0 -> 60. Airbrake, Rails 3.1 + Heroku

Part I: Setting up new Rails 3.1.x Project with Airbrake

1. Ensure you have the latest Rails 3.1.x gem:
   gem install rails
   => Successfully installed rails-3.1.1 (among others)

2. Create the rails app:
   rails new rails311app

3. Add airbrake to the app gems.
   cd rails311app
   echo "gem 'airbrake'" >> Gemfile
   bundle install

4. Then signup your project at AirbrakeApp.com and get the magic line:
   script/rails generate airbrake --api-key YOUR_API_KEY_GIVEN_ON_THE_WEB

5. You'll see a URL in the produced output like:
   
   16192005 http://mysubdomain.airbrakeapp.com/errors/1XXX/notices/2XXX 2XXX

6. Copy & Paste that URL (or just return to your AirbrakeApp.com account) and see the error. Welcome to a robust and worry-free production error removal workflow.

http://mysubdomain.airbrakeapp.com/errors/1XXX/notices/2XXX

Part II: Deploying to Heroku (without the addon)

1. Starting from where we left off--in the rails311app directory from above. Make a local git repo:
   git init
   git add .
   git commit -am "Initial import."

2. Then create the heroku app:
   heroku create rails311app

3. And push your code to heroku:
   git push heroku master

4. Then give the production error reporter a test:
   heroku run rake airbrake:test

4a. Aggh! This currently is broke. We're working with Heroku to debug. You'll see this error:
Started GET "/verify" for at 2011-10-09 11:54:04 -0700

ActiveRecord::ConnectionNotEstablished (ActiveRecord::ConnectionNotEstablished):

4b. Don't worry, your production errors are still caught. And you can test yourself with:
heroku console
Ruby console for rails311app.heroku.com
Airbrake.notify(:test => true)
=> "1XXX"
