Built out a simple Web Service in Ruby/Rails

I've been getting back to Rails.

After reading through some tutorials and going through a variety of teaching material, I was able to put together a project:
https://github.com/wbwarnerb/restapi/

A lot of this was generated by rails scaffolding.  
But the core code I wrote is in:
https://github.com/wbwarnerb/restapi/blob/master/lib/gwapi.rb
and
https://github.com/wbwarnerb/restapi/blob/master/lib/gwapiclient.rb
