@ -596,6 +596,21 @@ related ``Person`` *and* the related ``City``::
Note that ``select_related()`` does not follow foreign keys that have
``null=True``.
Usually, using ``select_related()`` can vastly improve performance because your
app can avoid many database calls. However, in situations with deeply nested
sets of relationships ``select_related()`` can sometimes end up following "too
many" relations, and can generate queries so large that they end up being slow.
In these situations, you can use the ``depth`` argument to ``select_related()``
to control how many "levels" of relations ``select_related()`` will actually
follow::
b = Book.objects.select_related(depth=1).get(id=4)
p = b.author # Doesn't hit the database.
c = p.hometown # Requires a database call.
The ``depth`` argument is new in the Django development version.
