queryset 查询结果集

遍历queryset 之后，可以直接获取当前对象的数据，item.ip.all() 获取的是queryset，_ip.x 可以直接获取数据，_ip 类型 <class 'monitoring.models.cloudServer'>

    def list(self, request):
        for item in alertPolicies.objects.all():
            _info = {}
            for _ip in item.ip.all():
                _process_name = []
                for process in _ip.processgroup_set.all():
                    _process_name = [ _process.get('process_name') for _process in process.processlist_set.values('process_name') ]
                _info[_ip.inner_ip_address] = _process_name
            print(_info)
