I haven't done this one in a while, but you need to make the CHOICES a tuple
or a list[1], not a queryset (unless there has been changes in this specific
area).
something like this:
def make_choices():
choices = []
for item in Province.objects.all()
choices.append((item.name, item.name))
return choices
# your form stuff
...
widgets = { 'name': Select(choices=make_choices()), }
The first value is the value stored, the second one is the human readable form
in the tuple.
