Question

I have this:

excl = dict()

kwargs['field1__isnull'] = False
kwargs['field2__isnull'] = False
kwargs['field3__isnull'] = False

items = MyModel.objects.filter(**kwargs).exclude(**excl)

And it generates this SQL:

SELECT ... FROM `mytable` WHERE (`field1` IS NULL  AND `field2` IS NULL AND `field2` IS NULL)

But I want this:

SELECT ... FROM `mytable` WHERE (`field1` IS NULL  AND `field2` IS NULL OR `field2` IS NULL)

How to do it (I must use kwargs dictionary, unless it can be combined with Q)?

Assuming danihp is correct with his question, I think you’d want something like this:

excl = dict()

f = Q(field1__isnull=False) | Q(field2__isnull=False) | Q(field3__isnull=False)

items = MyModel.objects.filter(f).exclude(**excl)
