partial_updates feature in rails 2.1, failing to save because of validate_presence _of on other attributes in the table
I am trying to use the new partial_updates feature in rails 2.1,
http://dev.rubyonrails.org/changeset/9157
but it is failing by trying to use all validations in the model
instead of just the changed attributes. The model works as I can
successfully .save(false) but if I try a regular .save I get an error
saying that it could not save becau...

ActiveRecord in Rails 2.1.0 misbehaving for Aggregate Attr.
...me.
In a nutshell: If you change an aggregate object attribute created via
composed_of method (see Agile Web Development - Second Edition Chapter
17 page 313 onwards) and then save the model, the change to the model
(composite attribute specifically) will not be saved UNLESS you
explicitly set the partial_updates attribute for that model to false.

Specific use-case:
I have an Account model that shadows the accounts table in database.
This account object contains a composite object (amongst others) called
BillingAddress defined within the Account model class as follows:
composed_of :billing_address,...

Rails 2.1 and default setting of Partial updates
...nd just needs to be edited: "Note: There''s
currently a config/initializers/new_rails_defaults.rb file that has this
setting, so edit that file if you have it."
However, in the new_rails_defaults.rb file in my new empty project does
not have that setting in it (ActiveRecord::Base.partial_updates = ...)
Yeah, I can add it, but I thought it should already be in there?
Thanks,
jt

Isn't there any performance issue when saving serialized attributes every time?
In edge rails, serialized attributes are saved every time no matter
they are changed or not:
def update_with_dirty
if partial_updates?
# Serialized attributes should always be written in case
they''ve been
# changed in place.
update_without_dirty(changed | (attributes.keys &
self.class.serialized_attributes.keys))
else
update_without_dirty
end...
