I'm wanting to re-render my index action in the event of an object not
getting saved; I use render not redirect so as to preserve the
I'm using the error_messages_for helper in my view but I get a
nil.errors error when I attempt to display the view.
I can avoid this error by setting up @discount = Discount.new in my
index action, but this obliterates the instance variable with the
attached error messages.
I'm chasing my tail on this and any clues would be appreciated.
