geonode-avatar 3.0.3

Basics

To integrate geonode-avatar with your site, there are relatively few things that are required. A minimal integration can work like this:

1. List this application in the INSTALLED_APPS portion of your settings file. Your settings file will look something like:

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

2. Add the pagination urls to the end of your root urlconf. Your urlconf will look something like:

   urlpatterns = patterns('',
       # ...
       (r'^admin/(.*)', admin.site.root),
       (r'^avatar/', include('avatar.urls')),
   )

3. Somewhere in your template navigation scheme, link to the change avatar page:

   <a href="{% url avatar_change %}">Change your avatar</a>

4. Wherever you want to display an avatar for a user, first load the avatar template tags:

   {% load avatar_tags %}

   Then, use the avatar tag to display an avatar of a default size:

   {% avatar user %}

   Or specify a size (in pixels) explicitly:

   {% avatar user 65 %}

5. Optionally customize avatar/change.html and avatar/confirm_delete.html to conform to your site’s look and feel.

Views

There are only two views for this application: one for changing a user’s avatar, and another for deleting a user’s avatar.

Template Tags

To begin using these template tags, you must first load the tags into the template rendering system:

{% load avatar_tags %}

{% avatar_url user [size in pixels] %}

Renders the URL of the avatar for the given user. User can be either a django.contrib.auth.models.User object instance or a username.

{% avatar user [size in pixels] %}

Renders an HTML img tag for the given user for the specified size. User can be either a django.contrib.auth.models.User object instance or a username.

{% render_avatar avatar [size in pixels] %}

Given an actual avatar.models.Avatar object instance, renders an HTML img tag to represent that avatar at the requested size.

Global Settings

There are a number of settings available to easily customize the avatars that appear on the site. Listed below are those settings:

AUTO_GENERATE_AVATAR_SIZES

An iterable of integers representing the sizes of avatars to generate on upload. This can save rendering time later on if you pre-generate the resized versions. Defaults to (80,)

AVATAR_RESIZE_METHOD

The method to use when resizing images, based on the options available in PIL. Defaults to Image.ANTIALIAS.

AVATAR_STORAGE_DIR

The directory under MEDIA_ROOT to store the images. If using a non-filesystem storage device, this will simply be appended to the beginning of the file name.

AVATAR_GRAVATAR_BACKUP

A boolean determining whether to default to the Gravatar service if no Avatar instance is found in the system for the given user. Defaults to True.

AVATAR_DEFAULT_URL

The default URL to default to if AVATAR_GRAVATAR_BACKUP is set to False and there is no Avatar instance found in the system for the given user.

Management Commands

This application does include one management command: rebuild_avatars. It takes no arguments and, when run, re-renders all of the thumbnails for all of the avatars for the pixel sizes specified in the AUTO_GENERATE_AVATAR_SIZES setting.
