Django Mailprotector

CI Version Licence PyPI Downloads

A reusable Django app that protects email addresses and phone numbers, in various ways. Django 1.8+, no further dependencies.


To get the latest stable release from PyPi

pip install django-mailprotector

Add mailprotector to your INSTALLED_APPS


If you want to use the mailprotector_textblock tag, you'll need to have beautifulsoup4 installed.


Before your tags/filters are available in your templates, load them by using

{% load mailprotector_tags %}

Then either email address after email address:

{% mailprotector '' link_text='link text' css_class='stylish' %}

Or as text block, for example from a rich text editor:

{% mailprotector_textblock object.richtext css_class='stylish' %}


MAILPROTECTOR_MODE = 'munger|munger_link_only'

This settings defines the protection algorithm used. Each has benefits and drawbacks...

  • munger: basic "munging" algo, replacing a mailto/tel link with a span, that gets filled with a new link. drawbacks: mailto are in dom, after a page is fully rendered with js (for example, with phantomjs). the link text can only be basic text, no html is possible. existing attributes (in textblock mode) will be removed (including class!) .

  • munger_link_only: "munging", but only with the href. benefits: all link attributes as well as link text including html is conserved drawbacks: for safety, emails and phone numbers (not yet) are protected in a basic way: @ = ' (at) ', . = ' . '

    email_pattern = r'\b[-.\w]+@[-.\w]+.[a-z]{2,6}\b' phone_pattern = r'\d{3} \d{3} \d{2} \d{2}'

    MAILPROTECTOR_EMAIL_PATTERN = re.compile(r'(' + email_pattern + r')') MAILPROTECTOR_PHONE_PATTERN = re.compile(r'(' + phone_pattern + r')')

For the mailprotector_textblock tag, you can yourself define the used regexes. Following are the defaults. If any of these are None, it is omitted during protection. WARNING: The default phone pattern is going to change to a more international default!
