Many-to-many relationships between the same two tables
In this example, a ``Person`` can have many friends, who are also ``Person``
objects. Friendship is a symmetrical relationship - if I am your friend, you
are my friend. Here, ``friends`` is an example of a symmetrical
``ManyToManyField``.
A ``Person`` can also have many idols - but while I may idolize you, you may
not think the same of me. Here, ``idols`` is an example of a non-symmetrical
``ManyToManyField``. Only recursive ``ManyToManyField`` fields may be
non-symmetrical, and they are symmetrical by default.
This test validates that the many-to-many table is created using a mangled name
if there is a name clash, and tests that symmetry is preserved where
appropriate.
