>>> sally = Teacher.objects.create(name='Sally')

>>> joe = Child.objects.create(name='Joe', teacher=sally, parent=john)

The problem depends only on InlineAdminForm and its "original" argument, so
we can safely set the other arguments to None/{}. We just need to check that
the content_type argument of Child isn't altered by the internals of the
inline form.

>>> from django.contrib.admin.helpers import InlineAdminForm
>>> iaf = InlineAdminForm(None, None, {}, {}, joe)
>>> iaf.original
<Child: I am Joe, a child of John>
