Answer 1

While saving and createing reply, you need to assign crave attribute as well.

Update your code to

        reply = form2.save(commit=False)
        reply.person=request.user
        reply.crave = crave_made
        reply.save()

Assuming you want to save with crave_made created just before.

Answer 2

Have you tried using commit=True, when you save the form? The error you are getting is telling you that the reply needs to be saved before you can add a foreign key relationship.
