I think I was really looking for something that would act as an
initialization even if I wasn't necessarily saving the object to
the database. "after_initialize" seemed like the right thing until
I found the somewhat dramatic extra effect of overwriting fields
in find() results. I probably just need to overwrite new() or
something, but for now I'll just work around it.
