django-broadcasts

This version of Django Site Broadcasts was forked to provide a way to schedule client-side messages:

• Across the whole site or on specific pages
• For a specified amount of time
• Uses a cookie to mark that the message was shown
• For all users, authenticated users only, or unauthenticated users only
• Retrievable via AJAX to allow for page caching
• Django 1.5+ compatibility

Installation

1. Use pip to install the application:

   $ pip install django-site-broadcasts

2. Then add broadcasts to your INSTALLED_APPS setting:

   INSTALLED_APPS = [
       # ...
       'broadcasts',
   ]

3. Add this line to your urls.py:

   url(r'^messages/', include('broadcasts.urls')),
   

Usage

If you have this in your HTML somewhere:

<div id="messages"></div>

you can use this simple jQuery snippet to retrieve all available broadcasts:

<script type="text/javascript" src="http://code.jquery.com/jquery-1.10.2.min.js"></script>
<script type="text/javascript">
    function addMessage(message) {
        $('#messages').append('<div class="alert">' + message + '</div>');
    };
    $.getJSON("{% url 'broadcast_messages' %}", function(data){
        $.each(data, function(index, value) {addMessage(value.message)});
    });
</script>
