You should always populate your form in forms.py. This is done using the
'initial' kwarg and is thoroughly explained in the docs! [1]
Borrowing from the tutorial's Poll model [2]:
Class PollsForm(forms.Form):
def __init__ (self, *args, **kwargs):
self.instance = kwargs.pop('instance', None)
if self.instance.pk is not None:
kwargs['initial'] = kwargs.get('initial', {})
kwargs['initial'] = {'question': self.instance.question}
super(PollsForm, self).__init__(*args, **kwargs)
This way, you can edit a Poll object by calling
PollsForm(instance=some_poll_object),
and it will automatically populate 'question' with the instance's
question attribute.
