Question

In a Django mobile web app I'm building, I'm using the sms html tag in one particular template. I.e. the typical <a href="sms:/* phone number here */?body=/* body text here */">Link</a>. Every time the user presses Link, they're redirected to their phone's default SMS app with a prepopulated message.

How can one implement a counter that increments every time a user clicks Link? The challenge is to solely use Python/Django (server-side), no JS.

您可以实施模型来跟踪Link的点击次数。要跟踪，您可以创建重定向视图之类的内容，在跟踪点击后重定向到sms URI。

一个基本的例子是：

from django.http.response import HttpResponseRedirect, HttpResponseRedirectBase

HttpResponseRedirectBase.allowed_schemes += ['sms']

class SMSRedirect(HttpResponseRedirect):
    pass

def track_count(request):
    phone = request.GET.get('phone', '')
    body = request.GET.body('body', '')
    link = build_sms_link(phone, body)
    link.hits += 1
    link.save()
    return SMSRedirect(link.url)

默认情况下，HttpResponseRedirectBase不允许非网络方案/协议。您可以通过猴子修补其允许的方案列表来允许它。

为<code>end</code>保留<a> tag (non-JS)
