served
by a OneToOneField."

When upgrading from Django 1.7 to Django 1.8 using the runserver command,
we noticed we get plenty of the following warnings:
mode.field_name: (fields.W342) Setting unique=True on a ForeignKey has the
same effect as using a OneToOneField.
HINT: ForeignKey(unique=True) is usually better served by a
OneToOneField.
We found that ForeignKey with unique scales usually better for two
reasons:
1) no need to handle None
2) changing from unique to non-unique is straight forward as one already
works with collections
Is there a way to suppress/remove that warning ?
