How would I use django.forms to prepopulate a choice field with rows from a model?

Question

I have a ChoiceField in my form class, presumably a list of users. How do I prepopulate this with a list of users from my User model?

What I have now is:

Answer 1

class MatchForm(forms.Form):
  choices = tuple(User.objects.all().values_list())

  user1_auto = forms.CharField()
  user1 = forms.ChoiceField(choices=choices)
  user2_auto = forms.CharField()
  user2 = forms.ChoiceField(choices=choices)

This should work.
