ModelForm with OneToOneField in Django
You have to create second form for PrinterAddress and handle both forms in you view:
if all((profile_form.is_valid(), address_form.is_valid())): profile = profile_form.save() address = address_form.save(commit=False) address.printer_profile = profile address.save()Of course in the template you need to show both forms under one <form> tag :-)
<form action="" method="post"> {% csrf_token %} {{ profile_form }} {{ address_form }}</form>
Complementing the accepted answer:
If you have custom clean methods, you need to add a try/except case. For the example presented if address had a clean() method to validate something you needed to change it to:
def clean(self): try: printer_profile = self.printer_profile except ObjectDoesNotExist: pass else: ...code to validate address...
