django-messages-ui 1.0.0

Getting Started

django-messages-ui can be used as a standalone jQuery plugin for adding and removing client-side messages, or as a Django add-on to additionally support the Django contrib.messages app. It should be called on the message list element, and accepts options for message selectors, transient messages (that disappear on click or key-press), and close-links. The messages themselves should be styled with CSS.

Messages can be dynamically added via Handlebars.js or ICanHaz.js, and if used as a Django plugin there’s a Python middleware to automatically add messages from the request into Ajax JSON responses.

Dependencies

• jQuery library

• jQuery doTimeout plugin

• (optionally) handlebars.runtime.js 1.0.0

• (optionally) ICanHaz.js

• (optionally) django-icanhaz 0.2.0+

Installation as a Standalone jQuery Plugin

If using as a standalone jQuery plugin, download the production version or the development version, along with either the Handlebars.js precompiled template or the ICanHaz.js template.

Linking the JS:

<script src="dist/django-messages-ui.min.js"></script>

If using Handlebars.js, also include the precompiled JS template:

<script src="messages_ui/static/messages_ui/message.js"></script>

To override the default JS template using Handlebars.js, link to your own precompiled JS file with a message template.

If using ICanHaz.js, wrap the ICanHaz.js template (or your own custom template, if you don’t want to use the default template) in a <script id="message" type="text/html"> tag and include it in your HTML, or import it in JS using ich.addTemplate('message', YOUR_TEMPLATE_STRING).

Installation with Django

If using with Django, just pip install django-messages-ui to install (or download the tarball from PyPI, unpack it, and run python setup.py install). In your Django project settings, add "messages_ui" to your INSTALLED_APPS setting.

Linking the JS:

<script src="{% static 'messages_ui/django-messages-ui.js' %}"></script>

If using Handlebars.js, also include the precompiled JS template:

<script src="{% static 'messages_ui/message.js' %}"></script>

Including the default HTML template:

{% include "messages_ui/_messages.html" %}

If using ICanHaz.js to insert messages on the client side, use this template instead:

{% include "messages_ui/_messages_ich.html" %}

To override the default JS template using Handlebars.js, link to your own precompiled JS file with a message template.

To override the default JS template using ICanHaz.js and django-icanhaz, add a message.html file to a directory listed in your ICANHAZ_DIRS setting.

Usage

Calling the plugin:

$('#messages').messages();

Calling the plugin with a variety of options explicitly configured to their default values:

$('#messages').messages({
    message: '.message',          // Selector for individual messages
    closeLink: '.close',          // Selector for link to close message
                                  //  ...set to ``false`` to disable
    closeCallback:                // Fn called when closeLink is clicked
        function (el) {
            el.stop().fadeOut('fast', function () {
                el.remove();
            });
        },
    transientMessage: '.success', // Selector for transient messages
    transientDelay: 500,          // Transient message callback delay (ms)
    transientCallback:            // Fn called after transientDelay
        function (el) {
            el.fadeOut(2000, function () { el.remove(); });
        },
    handleAjax: false,            // Enable automatic AJAX handling
    templating: 'handlebars',     // JS templating engine
                                  //  ...set to ``ich`` to use ICanHaz.js
    escapeHTML: true              // Set ``false`` to display unescaped
                                  // HTML in message content
});

Adding a message in JS:

$('#messages').messages('add', {message: "Sample Message", tags: "info"});

Adding a message with unescaped HTML in JS:

$('#messages').messages('add', {message: "<a href='/'>Sample Message</a>", tags: "info"}, {escapeHTML: false});
