Ruby Science Rails Example app
It's a Rails 3.2 app.
The application allows users to sign up and create surveys. Other users can then sign in and answer the questions on the survey. The basic requirements are similar to Wufoo.
Running the app
Make sure you're running Ruby 2.0 (there's a .ruby-version) and then:
bundle bundle exec rake db:create db:migrate bundle exec rails server
Open on http://localhost:3000
