You're missing something. You are assuming that setting Foo.id to be None will create a new Bar object. Since "id" is not the primary key of the Bar model, this won't be the case. Your code is creating another copy of Foo and then changes the parent to which the shabda object points. The primary key of shabda doesn't change throughout this process.
