[1.6.x] Added more examples to the get_object_or_404 documentation.

------------------

``klass``

    A :class:`~django.db.models.Model`, :class:`~django.db.models.Manager` or

    :class:`~django.db.models.query.QuerySet` instance from which to get the

    object.

    A :class:`~django.db.models.Model` class,

    a :class:`~django.db.models.Manager`,

    or a :class:`~django.db.models.query.QuerySet` instance from which to get

    the object.

``**kwargs``

    Lookup parameters, which should be in the format accepted by ``get()`` and

        except MyModel.DoesNotExist:

            raise Http404

The most common use case is to pass a :class:`~django.db.models.Model`, as

shown above. However, you can also pass a

:class:`~django.db.models.query.QuerySet` instance::

    queryset = Book.objects.filter(title__startswith='M')

    get_object_or_404(queryset, pk=1)

The above example is a bit contrived since it's equivalent to doing::

    get_object_or_404(Book, title__startswith='M', pk=1)

but it can be useful if you are passed the ``queryset`` variable from somewhere

else.

Finally, you can also use a :class:`~django.db.models.Manager`. This is useful

for example if you have a

:ref:`custom manager<custom-managers>`::

    get_object_or_404(Book.dahl_objects, title='Matilda')

You can also use

:class:`related managers<django.db.models.fields.related.RelatedManager>`::

    author = Author.objects.get(name='Roald Dahl')

    get_object_or_404(author.book_set, title='Matilda')

Note: As with ``get()``, a

:class:`~django.core.exceptions.MultipleObjectsReturned` exception

will be raised if more than one object is found.
