私は次のようなフォームを渡しています:

guest = get_object_or_404(Guest, id=guest_id)
data = {'full_name': guest.full_name, 'street_address': guest.street_address,
        'city': guest.city, 'state': guest.state, 'zip_code': guest.zip_code, 
        'guests': guest.guests, 'children': guest.children,'email': guest.email,
        'phone_number': guest.phone_number, 'gift_description': guest.gift_description,
        'status': guest.status.all()}

form = GuestForm(initial=data)

次のような投稿を介してフォームデータを取得します。

form = GuestForm(request.POST)
if form.is_valid():
    full_name = form.cleaned_data['full_name']
    street_address = form.cleaned_data['street_address']
    city = form.cleaned_data['city']
    state = form.cleaned_data['state']
    zip_code = form.cleaned_data['zip_code']
    guests = form.cleaned_data['guests']
    children = form.cleaned_data['children']
    email = form.cleaned_data['email']
    phone_number = form.cleaned_data['phone_number']
    gift_description = form.cleaned_data['gift_description']
    status = form.cleaned_data['status']

    guest = Guest.objects.filter(id=guest_id).update(user=request.user,
        full_name=full_name, street_address=street_address, city=city, 
        state=state, zip_code=zip_code, guests=guests, children=children,
        email=email, phone_number=phone_number, gift_description=gift_description,
        status=status) # The status is clearly not updated

これどうやってするの？

        model = Guest
        exclude = ['user', 'invitation_date']

modelForm のドキュメントを参照すると、 modelFormsを使用していてそれほど多くのコードを必要としない場合、コードは次のように縮小されます。

guest = get_object_or_404(Guest, id=guest_id)
form = GuestForm(instance=guest)

改めて投稿にあたり、

#get the guest instance, if updating existing record
form = GuestForm(request.POST, instance=guest)  
if form.is_valid():
    new_guest = form.save(commit=False) #you want to set excluded fields
    new_guest.user = request.user
    #new_guest.invitation_date = somedate
    new_guest.save()
    form.save_m2m() #should do this if save(commit=False) used
