您可以通过遵循查找中的向后关系来执行此操作。
>>> qs = Department.objects.filter(departmentvolunteer__isnull=True).values_list('name', flat=True)
>>> print(qs.query)
SELECT "app_department"."name" FROM "app_department" LEFT OUTER JOIN
"app_departmentvolunteer" ON ( "app_department"."id" = "app_departmentvolunteer"."department_id" )
WHERE "app_epartmentvolunteer"."id" IS NULL
