Usually this is exactly what you want to have happen. The only case where it
might be confusing is if you are using ``isnull``. Thus::
- Blog.objects.filter(entry__author__name__isnull=True)
+ Blog.objects.filter(entry__authors__name__isnull=True)
will return ``Blog`` objects that have an empty ``name`` on the ``author`` and
also those which have an empty ``author`` on the ``entry``. If you don't want
those latter objects, you could write::
- Blog.objects.filter(entry__author__isnull=False,
