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()

In the case where you have set form.save(commit=False) because you want to modify data and you have a many-to-many relation, then the answer is a little bit different:

def contact_create(request):
    if request.method == 'POST':
        form = ContactForm(request.POST)
        if form.is_valid():
            new_contact = form.save(commit=False)
            new_contact.data1 = "gets modified"
            new_contact.save()
            form.save_m2m()
            return HttpResponseRedirect(reverse(contact_details, args=(new_contact.pk,)))
    else:
        form = ContactFrom()
