        if request.user and request.user.is_authenticated:  # 必须是合法用户
            try:
                vip_group = Group.objects.get(name='vip')
                if vip_group in request.user.groups.all():  # 用户可能不属于任何分组
                    return True  # 必须是vip分组用户
            except:
                pass
