使用postgres的2个模型的Django查询集不相交

from django.db.models import Q

# 获取两个模型的查询集
queryset1 = Model1.objects.all()
queryset2 = Model2.objects.all()

# 使用exclude()方法获取不相交的结果
result = queryset1.exclude(Q(id__in=queryset2.values('id')))

# 打印结果
for obj in result:
    print(obj)

from django.db import connection

# 编写自定义的SQL查询语句
sql = '''
    SELECT *
    FROM model1
    WHERE id NOT IN (
        SELECT id
        FROM model2
    )
'''

# 执行SQL查询语句
with connection.cursor() as cursor:
    cursor.execute(sql)
    result = cursor.fetchall()

# 打印结果
for row in result:
    print(row)
