Trying to make a form with 2 inputs - django

Question

I have two different forms in my register page as the one to one relationship in one of the model will show a drop down box therefore I am using the second models field where the user will have to input the field.
How would I make it so when the forms are valid, the 'SNI' will save to the first form and not the second.

In views please refer to the registerPage function. Thank you

What the first form can take is Sni_id.
There is no sni_id without first saving an sni instance.
What you can do is...
Save both forms
f=form.save()
f2=form2.save()
f2.instance.user = f.instance.id
UPDATE:
if form2.is_valid():
sni = form2.data["sni"]
used = form2.data["used"]
if SNI.objects.filter(sni=sni, used=used).exists()
f=form.save()
