SwampDragon-live 0.0.7a0

[SwampDragon-live](https://github.com/mback2k/swampdragon-live) is an
extension to [Django](https://www.djangoproject.com/) and
[SwampDragon](http://swampdragon.net/) with SwampDragon-auth and django-redis
which adds support for live updating Django template snippets on model changes.

Installation
------------
Install the latest version from pypi.python.org:

pip install SwampDragon-live

Install the development version by cloning the source from github.com:

pip install git+https://github.com/mback2k/swampdragon-live.git

Configuration
-------------
Add the package to your `INSTALLED_APPS`:

INSTALLED_APPS += (
'swampdragon',
'swampdragon_live',
)

Example
-------
Make sure to use django-redis as a Cache backend named 'swampdragon-live' or 'default':

CACHES = {
'swampdragon-live': {
'BACKEND': 'django_redis.cache.RedisCache',
'LOCATION': 'redis://localhost:6379/0',
'OPTIONS': {
'CLIENT_CLASS': 'django_redis.client.DefaultClient',
}
}
}

Make sure to add the following line to your Django settings file:

SWAMP_DRAGON_CONNECTION = ('swampdragon_auth.socketconnection.HttpDataConnection', '/data')

Load the required JavaScript template-tags within your Django template:

{% load swampdragon_tags %}
{% load swampdragon_live %}

Add the required JavaScript to your Django template:

{% swampdragon_settings %}
<script type="text/javascript" src="{{ STATIC_URL }}swampdragon/js/dist/swampdragon.min.js"></script>
<script type="text/javascript" src="{{ STATIC_URL }}swampdragon/js/live/swampdragon.live.js"></script>

Use the include_live template-tag instead of the default include template-tag,
with rows being a Django database QuerySet to listen for added, changed, deleted instances:

{% include_live 'table' 'includes/table_body.html' rows=rows perms=perms %}

Use the include_live template-tag instead of the default include template-tag,
with row being a single Django database Model instance to listen for changes:

{% include_live 'table-row' 'includes/row_cols.html' row=row perms=perms %}

Use the swampdragon_live variable within the included template to add the
required classes to the root-tag of this template, e.g. the first tag-node:

<tr class="{{ swampdragon_live }}">...</tr>

You can check if your template is being live rendered by a content pusher by
using the context variable `is_swampdragon_live` like this:

{% if is_swampdragon_live %}
<style onload="alert('Hello World!');"></style>
{% endif %}
