TypeError: unsupported operand type(s) for |: 'bool' and 'Q'

Question

I'm running Django 1.7 and I'm getting TypeError: unsupported operand type(s) for |: 'bool' and 'Q' when trying to do the following:

class PersonList(generic.ListView):
    template_name = "persons/list.html"
    model = Person
    queryset = Person.objects.filter(Q(field1__isnull=True | Q(field2__isnull=True)))

Answer 1

In the example code, brackets are not where they are supposed to be when working with models.Q.

Solution:

Person.objects.filter(Q(field1__isnull=True) | Q(field2__isnull=True))

Mind the closing bracket.
