I had the same question and your self-answer helped me get started. But I also found another post (question-12399803) that completed the answer, that is, how to filter when creating a new entry.

In views.py

form = CustomerForm(groupid=request.user.groups.first().id)

In forms.py

def __init__(self, *args, **kwargs):
    if 'groupid' in kwargs:
        groupid = kwargs.pop('groupid')
    else:
        groupid = None
    super(CustomerForm, self).__init__(*args, **kwargs)
    if not groupid:
        groupid = self.instance.group.id
    self.fields['address'].queryset = Address.objects.filter(group_id=groupid)

So, whether adding a new customer or updating an existing customer, I can click on a link to go add a new address that will be assigned to that customer.

This is my first answer on StackOverflow. I hope it helps.
