I've just released django-protocolify on Github. It's basically a Django app that has a template tag that allows you to dynamically change the protocol of URLs within a section of a template. This can be useful if you want to force all the links in an existing block to use HTTPS rather than HTTP.

Consider the following base.html:

<!DOCTYPE html>
    <title>django-protocolify demo</title>
    {% block navigation %}
        <li><a href="{% url home %}">Home</a></li>
        <li><a href="{% url shop %}">Shop</a></li>
        <li><a href="{% url about_us %}">About Us</a></li>
    {% endblock navigation %}
    <div class="content">
    {% block content %}
        <p>No content here</p>
    {% endblock content %}

Now consider being on a "Payments" page that uses HTTPS. If the user clicks on
one of the navigation links from the base template, they'll still be using
HTTPS. django-protocolify solves this:

{% extends "base.html %}
{% load protocolify %}

{% block navigation %}
{% protocolify to "http" %}
{{ block.super }}
{% endprotocolify %}
{% endblock %}


If it sounds useful, go and check it out.
