Static assets

Add notices/css/notices.css and notices/js/notices.js to your markup.

Usage

In templates, load the tags:

{% load notices_tags %}

and add the modal:

{% NoticesModal %} 

The modal will be shown. Once it has been dismissed it won't be shown again unless the notice version changes (see below) or the notice_seen cookie is deleted.

Setting/updating the notice

via models and django admin

Add a Notice instance in the django admin.

Notices have title, content, version and optional expires_at fields.

Version can be any positive number; it defaults to incrementing the last version number. Set the expires_at datetime to avoid showing this notice after the specified date, even if the user has never seen/dismissed it.

To show a new notice, add another Notice instance with an incremented version number.

via django settings

Override the Notice model by adding to your settings.py: NOTICES_VERSION # an integer NOTICES_TITLE # optional, default = "New!" NOTICES_CONTENT # optional, default = ""

Set NOTICES_VERSION = 0 to clear the cookie and disable showing notices at all.
