django_user_messages 0.3.0

Installation

• Install django-user-messages using pip into your virtualenv.

• Add user_messages to INSTALLED_APPS and run migrate.

• Replace the default messages context processor with user_messages.context_processors.messages. The context processor provides both django.contrib.messages’ and django-user-messages’ messages.

• Use user_messages.api as you would use django.contrib.messages except that you pass the user model or ID as first parameter, not the current request.

Usage

Pretty much the same as Django’s messaging framework:

from user_messages import api

api.info(user, 'Hey there')
api.warning(user, 'Stop this')
api.error(user, 'Not nice!')

# Passing the ID is also possible; the user instance does not
# have to be instantiated at all:
api.success(user.id, 'Yay!')

django-user-messages’ messages supports two additional features not available in Django’s messages framework:

• Messages can be delivered more than once by passing deliver_once=False. These messages have to be acknowledged explicitly. django-user-messages does not contain any code to do this.

• It is possible to attach additional data by passing a dictionary as meta:

  api.debug(user, 'Oww', meta={
      'url': 'http://example.com',
  })

For convenience, our messages have the same tags and level_tag properties as Django’s messages. Meta properties are also accessible in templates:

{% if messages %}
  <ul class="messages">
    <li class="{{ message.tags }}".>
      {% if message.meta.url %}<a href="{{ message.meta.url }}">{% endif %}
      {{ message }}
      {% if message.meta.url %}</a>{% endif %}
    </li>
  </ul>
{% endif %}
