I have three fields_for inside a form_tag.
Two of them, correspond to the same model, :customer, (the two
objects, billing_customer and shipping_customer have been built in the
controller method). When I submit the form, the parameters only
include one of the two fields_for methods and it comes through as the
model name, not the object name:
I know there is a way to use two fields_for sections that correspond
to the same model... what am I doing wrong here?
