Question

How do I get the primary key after saving a ModelForm? After the form has been validated and saved, I would like to redirect the user to the contact_details view which requires the primary key of the contact.

def contact_create(request):     if request.method == 'POST':         form = ContactForm(request.POST)         if form.is_valid():             form.save()             return HttpResponseRedirect(reverse(contact_details, args=(form.pk,)))     else:         form = ContactForm()

The ModelForm‘s save method returns the saved object.

Try this:

def contact_create(request):     if request.method == 'POST':         form = ContactForm(request.POST)         if form.is_valid():             new_contact = form.save()             return HttpResponseRedirect(reverse(contact_details, args=(new_contact.pk,)))     else:         form = ContactForm()
