Comment (by master): The regression test added by the PR (test_union_with_two_annotated_values_list()) seems to have an unnecessarily complex combination, just to comply with a mandatory ordering of fields imposed by the union. Instead of: {{{ .annotate(count=F('num'),).annotate(num=Value(1, IntegerField()), }}} This writing is more understandable: {{{ .annotate(num=F('num'),).annotate(count=Value(1, IntegerField()), }}} -- Ticket URL: <https://code.djangoproject.com/ticket/29229#comment:8> Django <https://code.djangoproject.com/> The Web framework for perfectionists with deadlines. -- You received this message because you are subscribed to the Google Groups "Django updates" group.
