Well, what I am trying to achieve here is that no way two records are
created in B such that they belong to same record in A. For clear
explanation let me try to map the pr
yes and no
after_create is called after A has been saved, so it will be valid.
You'll have to make sure that the params for B are valid though
By calling create! instead of create, rails will raise an exception
if B is not valid but you could also write;
after_create(a)
B.create :a_id => a.

I would go with the observer so you can keep the logic in the model
(observer)...skinny controllers, fat models and all.

yea it turned out to be exactly the 'save' failure due to validation.

Yeah, it really belongs in the model...

Vipin,
wouldn't it be better moving this out of the controller altogether?
If every A should have a B then I'd create an observer - "AObserver"
and add an after_create callback:
class AObserver < ActiveRecord::Observer
def after_create(a)
B.create! :a_id => a.id
end
end

I wonder if @b.save is returning false? Maybe a validation issue?
Have you tried throwing a debugger statement in there?
