1.models层建立统计表

# 每日访问量统计class Statistics(models.Model):    pv = models.IntegerField(default=0)    uv = models.IntegerField(default=0)    date = models.CharField(max_length=200)    class Meta:        verbose_name = '网站统计信息'        verbose_name_plural = '网站统计信息'    def __unicode__(self):        return self.date

2.decorator.py建立装饰器函数

实现每次调用view试图函数前数据库字段先自加1

#!/usr/bin/env python# -*- coding=utf-8 -*-##################################from models import Statisticsimport timedef pvCount(func):    def wrapper(request, *args, **kwargs):        dateObj_list = Statistics.objects.filter(date=time.strftime('%Y-%m-%d'))        count = dateObj_list.count()        if count == 0:            Statistics.objects.create(pv=1,uv=0,date=str(time.strftime('%Y-%m-%d')))        else:            todayObj = Statistics.objects.get(date=str(time.strftime('%Y-%m-%d')))            todayObj.pv += 1            todayObj.save()        return func(request, *args, **kwargs)    return wrapper

3.view试图导入装饰器函数,并调用

from decorator import pvCount@pvCountdef index(request):    count = models.NewMachine.objects.all().count()    phycount = models.PhysicalHost.objects.all().count()    ret = dict()    ret['count'] = count    ret['phycount'] = phycount    # return HttpResponse('123456')    #logger.error("level info test")    return render_to_response('app/pages/index.html', ret)
