I don't understand why this approach didn't work. I do essentially this in
a form I have. I'd try a little harder to understand what went wrong here
before moving onto your other approaches. (You did remember to pass in
'firstSetOfFields' as a variable in your template context, right?).

Re: Need Help Iterating Through a Form With HTML Interspersed
P.S. I also tried using {% ifequals field.__repr__
form.field1.__repr__ %} to compare the objects, but Django
(intelligently) prevents you from accessing __ methods in templates.
