[Ruby] Adding multiple new related ActiveRecord objects

[James Moore]

I'm feeling some fuzziness around the concept of what's really dependant on
what. 

Can the children exist outside of the parent?  The mental model seems to be
"here's the definition of a company and some info about a contact; if the
company's already there, use the existing record.  Now add this contact to
the company."

Try restating the problem without worrying about ajax.  Ajax is fluff, not
meat; if you've got an interaction between how you think about your data and
ajax, something has gone horribly wrong.
