ROM + DRY Showcase

Each branch of this repo addresses a different article in the series that Ryan Bigg wrote.

I updated the dependencies, and updated the code according to the DRY release notes.

Type Along

The instructions need to tweaked in order for them to work. Following are updated commands.

1. To create the PostgreSQL database, run:

   sudo su postgres -c createdb bix_dev
   

2. Update bundler:

   bundle update --bundler
   

3. To generate a migration with ROM, run:

   bundle exec rake "db:create_migration[create_users]"
   

4. To run the migration, run:

   bundle exec rake db:migrate
   

5. Run the console app: Auto require doesn't seem to be working. Not sure how to fix these errors.
