File may be an unfortunate name for your ActiveRecord class since
it’s also a built in ruby class.
when you do find_by_id (same as just find BTW) your getting your
ActiveRecord class instance and when you do File.new your getting an
instance of the built in ruby class which does not contain a “name=”
that’s what I’m guessing anyway… checkout the RoR group;-)

Be who you are and say what you feel, because those who mind don’t
matter and those who matter don’t mind.
