django-email-obfuscator

A Django template filter to protect email addresses from crawlers.

Installation

Install from the Python package index:

$ pip install django-email-obfuscator

Add email_obfuscator to INSTALLED_APPS in settings.py:

INSTALLED_APPS = (
    # ...
    'email_obfuscator',
)

Usage

In your templates, you can protect email addresses with the obfuscate filter:

{% load email_obfuscator %}
{{ 'your@email.com'|obfuscate }}

The email address will be encoded with ASCII character entities, protecting it from spambots but rendering it readably in web browsers.

You can also use the filter to create clickable mailto links:

{% load email_obfuscator %}
{{ 'your@email.com'|obfuscate_mailto }}
#returns '<a href="mailto:your@email.com">your@email.com</a>' as an encoded string like
#<a href="&#109;&#97;&#105;&#108;&#116;&#111;&#58;&#121;&#111;&#117;&#114;&#64;&#101;&#109;&#97;&#105;&#108;&#46;&#99;&#111;&#109;">&#121;&#111;&#117;&#114;&#64;&#101;&#109;&#97;&#105;&#108;&#46;&#99;&#111;&#109;</a>

And if you want to add a custom link text, use this filter:

{% load email_obfuscator %}
{{ 'your@email.com'|obfuscate_mailto:"my custom text" }}
#returns '<a href="mailto:your@email.com">my custom text</a>' as an encoded string like
#<a href="&#109;&#97;&#105;&#108;&#116;&#111;&#58;&#121;&#111;&#117;&#114;&#64;&#101;&#109;&#97;&#105;&#108;&#46;&#99;&#111;&#109;">my custom text</a>
