Well... if you want a single form, define a single form:
class MyForm(Form):
phone = fields.CharField(max_length=8)
email = fields.CharField(max_length=50)
name = fields.CharField(max_length=50)
...
If you want to automatically generate a single form, you're out of
luck. A ModelForm operates on a single model class. You can't build a
model class for two models.
However, this isn't a major problem. There's no requirement that you
use a single form in a view. You can easily use multiple forms in a
single view - for example:
def edit_client(request, pk):
client = get_object_or_404(Client, pk=pk)
if request.method == "POST":
contact_form = ContactForm(instance=client.contact, data=request.POST)
client_form =ClientForm(instance=client, data=request.POST)
if client_form.is_valid() and contact_form.is_valid():
client_form.save()
contact_form.save()
return HttpResponseRedirect(...)
else:
contact_form = ContactForm(instance=client.contact)
client_form =ClientForm(instance=client)
return render_to_response(...)
