django conditionally filtering objects

Question

I would like to retrieve a bunch of rows from my database using a set of filters.

I was wondering if conditional filter is applicable in django. That is, \"filter if

Answer 1

from django.db.models import Q

qs = Users.objects.filter(
                    p_id=parent_id,
                    status=True
                ).all()

if user_id>0:
    qs = qs.filter( ~Q(id=user_id) )

in qs we will get the filtered results
