If I had my very own sweaty, wind-up Ballmer
(http://www.ntk.net/ballmer/mirrors.html warning: mind-scarring
video), that is what he would be saying:
“Relationships, relationships, relationships!!”
My unscientific polling of the traffic in #rubyonrails and here is
that, second to deployment issues, this is the bigges FAQ for Rails:
how to do relationship x in ActiveRecord.
There seems to be a lack of definitive and clear documentation for how
to handle various kinds of relationships with ActiveRecord. So,
somebody take the ball and run with it and put together a Guide to
ActiveRecord Relationships already!!
