saving associated models...is there any order to it?

Hi,

If I have 2 models defined as such:

class ClassA < ActiveRecord::Base   before_create "class_b.foo"   has_one :class_b   def foobar     puts "foobar"   end end

ClassB < ActiveRecord::Base   after_create :bar   belongs_to :class_a   def foo     puts "foo"   end   def bar     class_a.foobar   end end

And somewhere I do this:

a = ClassA.new b = ClassB.new a.class_b = b a.save

Which object will get created first, and in turn, have it's lifecycle method called first? In other words, will ClassA definitely get created before ClassB, or vise versa? Is there any guarantee to the order of saving objects in the graph?

Thanks in advance,

Ryan
