I had issues installing Postgres with the instructions in this Railscast. However I was able to get postgres running on my project with http://postgresapp.com/ and http://inductionapp.com/ (Hat tip to this stackoverflow thread).

1. Download & install Postgres.app (documentation) Make sure to install in /Applications.
2. Update your PATH
   In my case I added the following to ~/.bash_profile
   export PATH="/Applications/Postgres.app/Contents/MacOS/bin:$PATH"
   Check that Postgres.app is being loaded

$ which psql
/Applications/Postgres.app/Contents/MacOS/bin/psql

Description

Heroku is a simple way to publish your Rails app, and a powerful platform that will allow it to scale. In this episode, Jay McGavren gets you started with your first Heroku app.

Set up your Rails app

Isolate your gem environment

• You WANT Rails to fail locally if a gem isn't in your Gemfile

bundle exec isn't necessary for the rails command

You mention a sequence but book code doesn't have a sequence.

His email address? We’re using a handy feature provided by Factory Girl, called sequences.

launchy and guard-rspec are mentioned but they're not in the Gemfile

Though it's later explained that Factory() is a shortcut for Factory.create(). The section below might read more clearly with explicit calls to create()

Can you guess the difference? Factory.create() builds the model and saves it, while Factory.build() 
instantiates a new model, but doesn’t save it. If we used Factory.create() in this example it would break

How to Ruby Debug with Pow

Below are steps I followed to get ruby debugger ruby-debug running with Pow. Based on info from this thread basecamp/pow#43 and this blog post http://flochip.com/2011/04/13/running-pow-with-rdebug/

1) Update your Gemfile

Assuming you're writing your app in Ruby 1.9 and using Bundler, just add the dependency to your development gems:

Ruby Debugger

Most of the time simple output statements using warn, raise, or a logger will help you find your issue. But sometimes you need the big guns, and that means ruby-debug.

Ruby-Debug

The ruby-debug package has had some rocky times during the transition from Ruby 1.8.7 to 1.9.2 and beyond. But now, finally, the debugger is reliable and usable.
