I wish did fix the issue. This has nothing to do with Django, but with front-end stuff like CSS
You can do something like
{{ form.some_field }}
to access a certain field from 24 that you have and style it accordingly

seems to work fine Paolo Bergantino was on the right track, and helped me find it. This was the solution:
code :
def __init__(self, *args, **kwargs):
    super(MyForm, self).__init__(*args, **kwargs)

    instance = kwargs.get('instance')
    if instance:
        self.fields['pay_tourns'].initial = [ o.id for o in instance.tournaments.all().active().pay_tourns()]
        self.fields['rep_tourns'].initial = [ o.id for o in instance.tournaments.all().active().rep_tourns()]

may help you . I think you want to set the initial value of a field from other model field value if it is None:
code :
def __init__(self, *args, **kwargs):
    super(MyModelForm, self).__init__(*args, **kwargs)

    if self.instance.pk:
        if not self.initial.get('my_field'):
            self.initial['my_field'] = self.instance.parent.my_field

wish of those help I have a field in ModelForm that does not exist in model. The field is saved separately by overriding ModelForm.save() function: , To provide the initial data for the field use the initial parameter:
code :
form = MyForm(instance=my_obj, initial={'custom_field': 'Test'})
def __init__(self, *args, **kwargs):
    kwargs['initial'] = kwargs.get('initial', {})
    kwargs['initial']['custom_field'] = 'Test'
    super(MyForm, self).__init__(*args, **kwargs)

may help you . Just adding a field is not correct, considering the models above.
Address has a ManyToOne relation to Person - A user can have multiple addresses. In that case better take a look at django's inline form sets:
