I found this but it didn't answer my question. Say I have a Payment model, and PaymentConroller. I have the ability to create one payment, edit it, update etc... I also have a method payment_wizard. This method spreads payment according to parameters given in 'payment_wizard' form. But, I want a clean form when I spread new payments, to be able to update an existing collection of payments, and destroy all of them at once. This is making me think that the "right" thing to do would be to create a new controller PaymentWizardController which does all that.
Is this the right way to do this?
