[1.1.X] Fixed #10712 -- Added documentation for the queryset() method on...

This uses the ``HttpRequest`` instance to filter the ``Car`` foreign key field

to only the cars owned by the ``User`` instance.

.. method:: ModelAdmin.queryset(self, request):

The ``queryset`` method on a ``ModelAdmin`` returns a

:class:`~django.db.models.QuerySet` of all model instances that can be

edited by the admin site. One use case for overriding this method is

to show objects owned by the logged-in user::

    class MyModelAdmin(admin.ModelAdmin):

        def queryset(self, request):

            qs = super(self, MyModelAdmin).queryset(request)

            if request.user.is_superuser:

                return qs

            return qs.filter(author=request.user)
