限制Django每天的观看次数 [英] Limit number of views per day in Django

问题描述

是否有一种简单的方法来限制每天/每周给定IP地址可以访问视图的次数？一些书商的简化版本用于限制您可以预览的书的页数？

只有一个视图，这个限制需要适用于 - 即这不是一般限制 - 如果我可以在模板上下文中有一个变量 overlimit ，那将是很好的。解决方案不需要非常强大，但是通过IP地址限制似乎比使用cookie更好。

我已经研究了会话中间件，但是它不会对跟踪IP地址进行任何引用，只要我能够告诉

有没有人遇到这个问题？

解决方案

解决方案想出了使用 django-hitcount 应用程序和一个包装的原始视图。幸运的是，我有一个对象（页面），我可以与我想要限制的视图相关联，所以hitcount应用程序运行良好（大部分是预期的） / p>

我正在跟踪的视图是 line_list - 所以我打电话给新的视图来包装它 line_list_monitor 并将其与 line_list 的原始网址相关联。新视图包含在下面。如果有问题的IP超过了限制（每周20次），我将重定向到overlimit.html，否则原始视图就像正常调用一样。

  def line_list_monitor（request，character，pagenum）：
 LIMIT_HITS = 20 
 LIMIT_PERIOD = {'weeks'：1} 
 obj，created = Page.objects.get_or_create （character = character，page = pagenum）
 obj_pk = obj.pk 
 ctype = ContentType.objects.get_for_model（obj）
 hitcount，created = HitCount.objects.get_or_create（content_type = ctype， 
 object_pk = obj_pk）
 hit = Hit（session =，
 hitcount = hitcount，
 ip = get_ip（request），
 user_agent =）
 hit.save（）
 period = datetime.datetime.utcnow（） -  datetime.timedelta（** LIMIT_PERIOD）
 count = hitcount.hit_set.filter（ip = get_ip（request），
 created__gte = period）.count（）
如果count> 
 template =overlimit.html
 return render_to_response（template，context_instance = RequestContext（request））
 else：
 return line_list（请求，字符，页面）
  

Is there an easy way to limit the number of times a view can be accessed by a given IP address per day/week? A simplified version of the technique used by some booksellers to limit the number of pages of a book you can preview?

There's only one view that this limit need apply to--i.e. it's not a general limit--and it would be nice if I could just have a variable overlimit in the template context. The solution need not be terribly robust, but limiting by IP address seemed like a better idea than using a cookie.

I've looked into the session middleware but it doesn't make any references to tracking IP addresses as far as I can tell.

Has anyone encountered this problem?

解决方案

The solution I came up with harnessed the django-hitcount app and a "wrapping" of the original view. Luckily, I have an object (Page) that I can associate with the view I'm trying to limit, so the hitcount app works well (and mostly as intended).

The view I'm tracking is line_list -- so I called the new view to wrap it line_list_monitor and associated the original url for line_list with it. The new view is included below. If the IP in question is over the limit (20 views per week), I redirect to overlimit.html, else the original view just gets called like normal.

def line_list_monitor(request, character, pagenum):
    LIMIT_HITS = 20
    LIMIT_PERIOD = {'weeks': 1}
    obj, created = Page.objects.get_or_create(character=character, page=pagenum)
    obj_pk = obj.pk
    ctype = ContentType.objects.get_for_model(obj)
    hitcount, created = HitCount.objects.get_or_create(content_type=ctype,
                                                          object_pk=obj_pk)
    hit = Hit(session="",
              hitcount=hitcount,
              ip=get_ip(request),
              user_agent="")
    hit.save()
    period = datetime.datetime.utcnow() - datetime.timedelta(**LIMIT_PERIOD)
    count = hitcount.hit_set.filter(ip=get_ip(request),
                                    created__gte=period).count()
    if count > LIMIT_HITS:
        template = "overlimit.html"
        return render_to_response(template, context_instance=RequestContext(request))
    else:
        return line_list(request, character, page)
