Hi all, I am having trouble with a Q object look up in one of my apps. When I execute the following:
Tag.objects.filter(Q(card__owner = u)|Q(usercardmeta__user = u)) an empty queryset is returned. The filtered QuerySet should be returning this list: [<Tag: test (0)>, <Tag: tag-2 (0)>, <Tag: test2 (0)>, <Tag: testtag (0)>] After stepping through and grokking the code I think I have pinned the problem down to this line the QuerySet method _filter_or_exclude: clone._filters = clone._filters & reduce(operator.and_, map(mapper, args))long It appears that when the clone._filters and reduce() result are &'d together I am losing the QOr results because clone._filters is an "empty" Q object. At least that what it appears to be to me. This looks like it might fall under the ticket #2253 though I have not actually tried the problem described in the ticket. Should there be a check in the _filter_or_exclude method to see if clone._filters is an "empty" Q object and if so just assign the reduce() result to clone._filters directly?
