Test inline formsets where the inline-edited object has a custom primary key that is not the fk to the parent object.

>>> AuthorBooksFormSet2 = inlineformset_factory(Author, BookWithCustomPK, can_delete=False, extra=1)

>>> formset = AuthorBooksFormSet2(instance=author)

>>> for form in formset.forms:

...     print form.as_p()

<p><label for="id_bookwithcustompk_set-0-my_pk">My pk:</label> <input type="text" name="bookwithcustompk_set-0-my_pk" id="id_bookwithcustompk_set-0-my_pk" /></p>

    <p><label for="id_bookwithcustompk_set-0-title">Title:</label> <input id="id_bookwithcustompk_set-0-title" type="text" name="bookwithcustompk_set-0-title" maxlength="100" /><input type="hidden" name="bookwithcustompk_set-0-author" value="1" id="id_bookwithcustompk_set-0-author" /></p>

>>> data = {

...     'bookwithcustompk_set-TOTAL_FORMS': '1', # the number of forms rendered

...     'bookwithcustompk_set-INITIAL_FORMS': '0', # the number of forms with initial data

...     'bookwithcustompk_set-0-my_pk': '77777',

...     'bookwithcustompk_set-0-title': 'Les Fleurs du Mal',

... }

>>> formset = AuthorBooksFormSet2(data, instance=author)

>>> formset.is_valid()

True

>>> formset.save()

[<BookWithCustomPK: 77777: Les Fleurs du Mal>]

>>> for book in author.bookwithcustompk_set.all():
