ActiveResource Save and Create not passing data

Hi all,

I am having an issue with ActiveResource that I hope someone can clear
up for me.

For some reason I can't get any data passed via the api to persist in
the Database. If I create a new object, assign values to the parameters
and save it, and empty object is created in the db. If I try an update
an existing record the data doesn't change. I have verified that I can
make changes and add new object via the traditional UI, so I must be
missing something.

#!/usr/bin/env ruby
require 'activeresource'

class TestServer < ActiveResource::Base
    # ActiveResource needs to know the location
     # of the resource we're connecting to,
     # plus the login, if required
    self.site = 'http://localhost:3000'
    self.element_name ='testservers'
end

if have tried both

TS = TestServer.new(:name => "bbbbb")
TS.save

and

  TS = TestServer.new
  TS.name= "bbbbb"
  TS.save

neither seems to work. Can anyone tell me what I am doing wrong here?

Thanks
