About Bitwise OR
In Python and Django, if you have a list of elements that you need to combine with bitwise OR i.e. "|" operator, you can use the reduce() function for that. For example:
import operator
from django.db import models
list_of_Q_conditions = [
models.Q(is_urgent=True),
models.Q(is_important=True),
models.Q(is_significant=True),
]
qs = qs.filter(reduce(operator.ior, list_of_Q_conditions))
