Hello,  
I have two models. people and organisations  
they have a many to many relationship between them.  
I want to be able to create person in an organisation form and vice  
versa.  
the forms for them are according to the railscasts episode 75  
complex\_forms\_3. which is as follows

I have a organisation form(that is created dynamically) in the person  
form

class Organisation \< ActiveRecord::Base  
has\_and\_belongs\_to\_many :people  
after\_update :save\_organisations

def save\_people  
people.each do|p|  
if p.should\_destroy?  
p.destroy  
else  
p.save(false)  
end  
end  
end  
end

class Person \< ActiveRecord::Base  
has\_and\_belongs\_to\_many :organisations  
after\_update :save\_people

def save\_organisations  
organisations.each do|org|  
if org.should\_destroy?  
org.destroy  
else  
org.save(false)  
end  
end  
end  
end

Now when i create a person or an organisation the process never gets  
complete.  
Only when i comment any one of the after\_update statements The problem  
goes away. But in this case I can either create/update an organisation  
in the person form or a person in an organisation form depending upon  
which after\_update i have disabled.

can anyone tell mne whats going wrong and how do i correct it.

Thank you.
