#3548: add a direct mapping when using ForeignKey fields with unique=True in
place
of the deprecated OneToOneField

OneToOne ForeignKey unique direct mapping ORM
Stage: Unreviewed | Has_patch: 0
------------------------------------------------------------+---------------
OneToOneField sets up a direct mapping to the related object in the ORM,
e.g. when relating Profile in your app to User in contrib.auth, you can
access the profile with u.profile. as OneToOneField has a few issues and
is likely going away soon, could we change ForeignKey to add a similar
user friendly mapping when unique=True is specified, to save having to do
something like u.profile_set.all()[0].
when only using one model to extend User, you can use the
AUTH_PROFILE_MODULE setting and the User.get_profile() method, but this is
specific to User, and indicates the extending model is a "profile", and
can only be used with one extension of a model. for example, it may be
possible to have multiple apps within a project, which all share common
users, but each has specific extensions of User specific to their purpose.
it's also possible to want to extend other models besides User with a
OneToOne relation. in those cases, the direct mapping above would come in
handy. e.g. u.blog_profile, u.intranet_profile, etc.
