Rails - Jun 2005 - ActiveRecord::Base#save

When I save a model object, how far down the "object tree" will
objects be
saved?  Does it vary for previously saved vs. new objects?  

Thanks

If you''re referring to the association object tree then this is  
discussed in the ActiveRecord::Associations documentation:
http://api.rubyonrails.com/classes/ActiveRecord/Associations/ 
ClassMethods.html

Actually, I don''t think it does. Well, at least not entirely. After
persuing
the documentation, the closest I find is a discussion of when unsaved objects 
might or might not be saved automatically.  I find nothing about what happens 
when save is called explicitly with various dirty objects.

Consider this:

A has many Bs
B has _one C

If I have code like this:

a = A.find(id)
a.bs[0].c.foo = ''bar''
a.save

Should a.bs[0].c be saved?
