Problem when retrieving objects with AND over multiple OR statements

Reported by: Haisheng HU Owned by: nobody

I'm using Django 1.3 on MongoDB, and met a weird situation.


Q(owner=u'A') | Q(owner=u'B'),
Q(owner=u'C') | Q(owner=u'D'),


The above returned queryset is same to Project.objects.filter(Q(owner=u'C') | Q(owner=u'D')), but not None, as expected. It seems that the first half lookup function was omitted.

Does someone know that it's problem with Django or third-party mongodb-engine libraries? Thanks in ad!

It isn't a problem with Django:

>>> AutoName.objects.all()
[<AutoName: A>, <AutoName: C>]
>>> AutoName.objects.filter(Q(name=u'A') | Q(name=u'B'), Q(name=u'C') | Q(name=u'D'))
>>> AutoName.objects.filter(Q(name=u'A') | Q(name=u'B'))
[<AutoName: A>]
>>> AutoName.objects.filter(Q(name=u'C') | Q(name=u'D'))
[<AutoName: C>]
