This is really interesting! I created a simple app to CRUD Cities and Countries and it works as you expect it to. Code is also what I would have written given the simple spec.

Uses the latest Rails and clean code generation. Well done!

I'll use to launch my next project because Facebook+Email authentication is a pain in the ass to implement.
