Didn't see this when I sent the other. But yeah, I was
sort of assuming the transaction wrapping. I was still hoping
to do all my in-memory attribute futzing as a separate step
from the save() (seems clearer that way, allows for a single
separate "a.valid?" call, etc).

I havn't tested this, but If you want it to be transactional, try
wrapping it in:
Author.transaction do
a = Author.find(some_id)
a.update_attributes!({middle_name => "Poindexter"})
a.stories.find_by_title("The Lake").update_attributes!({title =>
"The Dry Lake"})
end
(Be sure to use either update_attributes! or save! so it will throw an
exception)

How bout...
a = Author.find(some_id)
a.update_attribute(middle_name, "Poindexter")
a.stories.find_by_title("The Lake").update_attribute(title, "The Dry Lake")

Sorry, fixing confusing typo:

Say I have a couple of tables:
author :has_many => stories
story :belongs_to => author
In a form handler I'd like to do something like:
a = Author.find(some_id)
a.middle_name = "Poindexter"
s = a.find_by_title("The Lake")
s.title = "The Dry Lake"
I'd like to then transactionally (or even not) do
a.save!
and have the change to "s" get saved as well. Is this possible?
It works fine if s is a new record created with build(), or something like
s = Story.new
a.stories << s
a.save!
Is there any magic like "<<" or build() that can be used for existing
objects to attach them to a parent object for purposes of
cascading the save()?
Thanks!
