Child has two ForeignKeys to Parent, so if we don't specify which one to use
|
|
for the inline formset, we should get an exception.

Traceback (most recent call last):

Exception: <class 'regressiontests.inline_formsets.models.Child'> has more than 1 ForeignKey to <class 'regressiontests.inline_formsets.models.Parent'>

These two should both work without a problem.

If we specify fk_name, but it isn't a ForeignKey from the child model to the

parent model, we should get an exception.
