A lightweight django-gravatar app. Includes helper methods for interacting with gravatars outside of template code.

If you like this library and it's saved you some time, please consider supporting further development with a Gittip donation!

Features

• Helper methods for constructing a gravatar url and checking an email for an existing gravatar
• Templatetags for generating a gravatar url or gravatar <img> tag.
• Full test suite!

Installing

Install from PyPi:

You can pip install the app directly from GitHub:

$ pip install git+git://github.com/twaddington/django-gravatar.git#egg=DjangoGravatar

Alternatively, you can now install directly from PyPi!

$ pip install django-gravatar2

Make sure you install django-gravatar2 as there are several other incompatible django-gravatar libraries available.

Add django_gravatar to your INSTALLED_APPS in settings.py:

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

# django-gravatar
