Or as a more general question, I reviewed the Railscast mentioned
above & Ryan Bates says that the Railscast shows a way to do multiple
models in one form by keeping the code tucked in the models and not
the controllers. Since the Railscast was done in 2007, has a
preferred method of doing multiple models in one form emerged? Is it
preferable to put code in the models keeping the controllers light or
is it preferred to put the code in the controllers and keep the models
light? Or is this still a design preference for the developer to
choose?
Thanks in advance for enlightment!
