以下是在模板中做一个简单的页面PV数统计、model阅读量统计、用户訪问量统计的方法

简单的模板页面计数的实现

模板中设置：

<li>您是第{{count}}个訪问本站的朋友</li>

<li>訪问时间:{{time}}</li>

view.py中

def getTime():#获取当前时间

    import time

    return time.ctime()

def getCount():#获取訪问次数

    countfile  = open('count.dat','a+')#以读写形式打开记录计数的文件

    counttext = countfile.read()

    try:

        count = int(counttext)+1

    except:

        count = 1

    countfile.seek(0)

    countfile.truncate()#清空文件

    countfile.write(str(count))#又一次写入新的訪问量

    countfile.flush()

    countfile.close()

    return count

def myHelloWorld(request):

    time = getTime()

    count = getCount()

    para = {"count":count,"time":time}

    ...

这样每次訪问时都会调用myHelloWorld函数。读取count值并+1操作

model对象的计数器实现

Django hit counter application that tracks the number of hits/views for chosen objects.

hit counter是用来计数model对象的訪问次数的。

安装django-hitcount:

pip install django-hitcount

# settings.py

INSTALLED_APPS = (

    ...

    'hitcount'

)

# needed for django-hitcount to function properly
SESSION_SAVE_EVERY_REQUEST = True

# urls.py

urlpatterns = patterns('',

    ...
url(r'hitcount/', include('hitcount.urls', namespace='hitcount')),

)

{% load hitcount_tags %}

{% load staticfiles %}

<script src="//code.jquery.com/jquery-1.11.3.min.js"></script>
<script src="{% static 'hitcount/hitcount-jquery.js' %}"></script>

# use default insertion method for hitcount-jquery.js:
{% insert_hit_count_js_variables for object %}

# or you can use a template variable to inject as you see fit
{% get_hit_count_js_variables for object as hitcount %}

({ hitcount.ajax_url }}

{{ hitcount.pk }}

# Return total hits for an object:

{% get_hit_count for [object] %}

# Get total hits for an object as a specified variable:

{% get_hit_count for [object] as [var] %}

# Get total hits for an object over a certain time period:

{% get_hit_count for [object] within ["days=1,minutes=30"] %}

# Get total hits for an object over a certain time period as a variable:

{% get_hit_count for [object] within ["days=1,minutes=30"] as [var] %}

页面的用户訪问量统计

django-tracking keeps track of visitors to Django-powered Web sites. It also offers basic blacklisting capabilities.

安装django-tracking

pip install django-tracking

Note:会出错： no module named listeners

配置

First of all, you must add this project to your list of INSTALLED_APPS insettings.py:

INSTALLED_APPS = (

    'django.contrib.admin',

    'django.contrib.auth',

    'django.contrib.contenttypes',

    'django.contrib.sessions',

    'django.contrib.sites',

    ...

    'tracking',

    ...

)

Run manage.py syncdb. This creates a few tables in your database that arenecessary for operation.

Depending on how you wish to use this application, you have a few options:

Visitor Tracking

Add tracking.middleware.VisitorTrackingMiddleware to yourMIDDLEWARE_CLASSES insettings.py. It must be underneath theAuthenticationMiddleware, so thatrequest.user exists.

Automatic Visitor Clean-Up

If you want to have Django automatically clean past visitor information outyour database, puttracking.middleware.VisitorCleanUpMiddleware in yourMIDDLEWARE_CLASSES.

IP Banning

Add tracking.middleware.BannedIPMiddleware to your MIDDLEWARE_CLASSESinsettings.py. I would recommend making this the very first item inMIDDLEWARE_CLASSES so your banned users do not have to drill through
anyother middleware before Django realizes they don't belong on your site.

Visitors on Page (template tag)

Make sure that django.core.context_processors.request is somewhere in yourTEMPLATE_CONTEXT_PROCESSORS tuple. This context processor makes therequest object accessible to your templates. This application uses therequest
object to determine what page the user is looking at in a templatetag.

Active Visitors Map

If you're interested in seeing where your visitors are at a given point intime, you might enjoy the active visitor map feature. Be sure you have added aline to your main URLconf, as follows:

from django.conf.urls.defaults import *

urlpatterns = patterns('',

    ....

    (r'^tracking/', include('tracking.urls')),

    ....

)

Next, set a couple of settings in your settings.py:

• GOOGLE_MAPS_KEY: Your very own Google Maps API key

• TRACKING_USE_GEOIP: set this to True if you want to see markers onthe map

• GEOIP_PATH: set this to the absolute path on the filesystem of yourGeoIP.dat orGeoIPCity.dat or whatever file. It's usually somethinglike/usr/local/share/GeoIP.dat or/usr/share/GeoIP/GeoIP.dat.

• GEOIP_CACHE_TYPE: The type of caching to use when dealing with GeoIP data:

  • 0: read database from filesystem, uses least memory.
  • 1: load database into memory, faster performance but uses morememory.
  • 2: check for updated database. If database has been updated, reloadfilehandle and/or memory cache.
  • 4: just cache the most frequently accessed index portion of thedatabase, resulting in faster lookups thanGEOIP_STANDARD, but lessmemory usage thanGEOIP_MEMORY_CACHE - useful for larger databasessuch as GeoIP Organization
    and GeoIP City. Note, for GeoIP Country,Region and Netspeed databases,GEOIP_INDEX_CACHE is equivalent toGEOIP_MEMORY_CACHE.default

• DEFAULT_TRACKING_TEMPLATE: The template to use when generating thevisitor map. Defaults totracking/visitor_map.html.

When that's done, you should be able to go to /tracking/map/ on your site(replacingtracking with whatever prefix you chose to use in your URLconf,obviously). The default template relies upon jQuery for its awesomeness, butyou're
free to use whatever you would like.

Usage

To display the number of active users there are in one of your templates, makesure you have{% load tracking_tags %} somewhere in your template and dosomething like this:

{% visitors_on_site as visitors %}

<p>

    {{ visitors }} active user{{ visitors|pluralize }}

</p>

If you also want to show how many people are looking at the same page:

{% visitors_on_page as same_page %}

<p>

    {{ same_page }} of {{ visitors }} active user{{ visitors|pluralize }}

    {{ same_page|pluralize:"is,are" }} reading this page

</p>

If you don't want particular areas of your site to be tracked, you may define alist of prefixes in yoursettings.py using theNO_TRACKING_PREFIXES. Forexample, if you didn't want visits to the/family/ section of your
website,setNO_TRACKING_PREFIXES to['/family/'].

If you don't want to count certain user-agents, such as Yahoo!'s Slurp andGoogle's Googlebot, you may add keywords to your visitor tracking in yourDjango administration interface. Look for "Untracked User-Agents" and add akeyword that distinguishes a particular
user-agent. Any visitors with thekeyword in their user-agent string will not be tracked.

By default, active users include any visitors within the last 10 minutes. Ifyou would like to override that setting, just setTRACKING_TIMEOUT to howevermany minutes you want in yoursettings.py.

For automatic visitor clean-up, any records older than 24 hours are removed bydefault. If you would like to override that setting, setTRACKING_CLEANUP_TIMEOUT to however many hours you want in yoursettings.py.
