Django - 使用Python Ping进行模型布尔检查

Question

我目前有一个可用于DSL连接的DSLAM管理站点。目前希望我想通过自动ping DSLAM IP地址来实现DSLAM状态更新。如果请求是好的，那么它将返回boolean = True并保存，否则boolean = False并保存。到目前为止，它不起作用，不知道从哪里开始。

models.py

from django.db import models
import os,sys

class DslamManager(models.Manager):
    def dslam_status(self, ip_address):
        if os.system('ping' + ip_address):
            dslam_status = super(DslamManager, self).get(ip_address)
            dslam_status = True
            dslam_status.save()
        else:
            dslam_status = super(DslamManager, self)
            dslam_status = False
            dslam_status.save()


class Location(models.Model):
    location_name = models.CharField(max_length=30)
    island_name = models.CharField(max_length=30)

    class Meta:
        ordering = ['location_name']

    def __unicode__(self):
        return self.location_name


class Dslam(models.Model):
    dslam_name = models.CharField(max_length=32)
    ip_address = models.CharField(max_length=128)
    location = models.ForeignKey(Location)
    notes = models.TextField(blank=True)
    dslam_status = models.BooleanField()
    objects = DslamManager()

    class Meta:
        ordering = ['location', 'id']

    def __unicode__(self):
        return self.dslam_name

我通过将其添加到ModelAdmin来修复此问题。它只需要一点时间来刷新，但这是因为它试图ping一个IP地址列表。

list_display = ('DSLAM_STATUS',)

def DSLAM_STATUS(self, obj):

    if os.system('ping -w 1 -n 1 ' + obj.ip_address):
        DSLAM_STATUS = False
    else:
        DSLAM_STATUS = True
    return DSLAM_STATUS

DSLAM_STATUS.boolean = True
DSLAM_STATUS.allow_tags = True

这只在某些时候有效，但我相信ping ip_address的时间太快了。
