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 Statistics

import time

def 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

@pvCount

def 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)
