django-装饰器实现PV统计

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)
