title: Adding additional fields (with validation) to Devise view/model in Rails app
body: <p>It seems there's not a whole lot of documentation out there covering how to add custom fields to a Devise authentication solution in a Rails 3 app. </p>
  
  <p>Along with the required e-mail and password for users to sign up, I'd like a few other custom fields put in and validated and since there are no controllers generated with Devise, how does one do this?</p>
