AR update and save child based on change in parent

I thought this would be straightforward, but I'm missing something

class User < AR::Base   has_one :profile, :dependent => :destroy end

class Profile < AR::Base   belongs_to :user end

Based on a field change in User, I want to update and save some values in Profile.

So, I have this in User:

def after_validation_on_update   if self.userType_changed?     self.some_local_field = '' # this works     self.profile.field_x = '' # this not being changed     self.profile.save # needed?   end end

The fields in User (self) are being updated just fine. But I can't seem to force the changes to fields in User.profile.

Stopping at the gas station for directions...

Thx

Oh brother. I did it again. Figured it out. A validation prevents me from me emptying that field, so the save was being rejected.
