Empty order_by() doesn't work with slice

[None]

MyModel.objects.order_by() - use SQL without ORDER BY.
MyModel.objects.order_by()[:10] - use SQL with ORDER BY (default fields for model ordering).

This is a bug or a feature? :)

Are you sure? How have you checked that ordering is applied? I've checked it in my project and everything works as expected (no ordering in both cases).

I also cannot reproduce the reported issue:

I added:

class Meta:
    ordering = ('id',)

to the Poll class in the tutorial.

>>> str(Poll.objects.all().query)
'SELECT "polls_poll"."id", "polls_poll"."question", "polls_poll"."pub_date" FROM "polls_poll" ORDER BY "polls_poll"."id" ASC'
>>> str(Poll.objects.order_by().query)
'SELECT "polls_poll"."id", "polls_poll"."question", "polls_poll"."pub_date" FROM "polls_poll"'
>>> str(Poll.objects.order_by()[:10].query)
'SELECT "polls_poll"."id", "polls_poll"."question", "polls_poll"."pub_date" FROM "polls_poll" LIMIT 10'
