You could do this:
a = choices.get_list()[0]
a.poll_id = 2
new_choice = choices.Choice(**a.__dict__())
new_choice.save()
This exploits the fact that Python objects have a built-in __dict__()
method that returns a dictionary of attribute -> value items. The "**"
(double asterisks) tell Python to expand the dictionary value into
keyword arguments. For example the following two statements are
functionally identical:
write_love_letter(to='python', from='adrian')
write_love_letter(**{'to': 'python', 'from': 'adrian'})
