Django model 基于boolean字段过滤

Question

I have a user model which has fields like these,

is_active = models.BooleanField()
date_joined = models.DateTimeField(auto_now_add=True)
resigned_date = models.DateTimeField(blank=True, null=True)

Where resigned_date will be None if is_active field is True . If is_active field is False then the resigned_date field will have the date. I think I can explain it.

What I want is to queryset of users based on some DATE and is_active field.

More clearly I want to get the list of employee that (is active and joined_date is less that or equal to the current date) and (is not active and resigned_date is greater that the current date)

The query I have written so far:

users = user_models.User.objects.filter(
                Q(
                     is_active=True,
                     date_joined__month__lte=month,
                     date_joined__year__lte=year,
                 )
              & Q(
                     is_active=False,
                     resigned_date__month__gt=month,
                     resigned_date__year__gt=year,
                 )
            )

But this is not working. It is not returning any users.

How can I achive this?

Thanks

I have managed to do this with this below method:

all_users = user_models.User.objects.filter(
                branch_id=branch_id,
                date_joined__month__lte=month,
                date_joined__year__lte=year,
            )

active_users = all_users.filter(
                is_active=True,

            )
inactive_users = all_users.filter(
                is_active=False,
                resigned_date__month__gt=month,
                resigned_date__year__gte=year,
            )
users = list(chain(active_users, inactive_users))

If using single query

users = user_models.User.objects.filter(
                Q(
                    branch_id=branch_id,
                    date_joined__month__lte=month,
                    date_joined__year__lte=year,
                ),
                Q(is_active=True)
                | Q(
                    resigned_date__month__gt=month,
                    resigned_date__year__gte=year,
                ),
            )
