Jim Neath's walkthru (http://jimneath.org/2008/09/06/multi-model-forms-
validations-in-ruby-on-rails/) talks about validating multiple objects
before saving. His example is below:
if @person.valid? & @cat.valid? & @dog.valid?
I am trying to do something similar but in my situation there may not
always be a @cat or @dog (there will always be a @person though).
Does anyone know of a way that I can run the same validation but allow
for the conditional presence of the 2 objects?
