Quickstart

Follow instruction for firing up django.contrib.messages, then install the app:

pip install django-stored-messages

Add it to the installed apps:

INSTALLED_APPS = (
    # ...
    'stored_messages',
)

In the settings, tell Django which is the message storage:

MESSAGE_STORAGE = 'stored_messages.storage.PersistentStorage'

Then use it in a project through the django.contrib.messages api. The app provides for convenience some message levels which are persisted by default:

import stored_messages
from django.contrib import messages

# standard message
messages.add_message(request, messages.INFO, 'Hello world.')
# this will be persisted and marked as 'unread'
messages.add_message(request, stored_messages.STORED_INFO, 'Hello world, to the database!')

stored_messages expose the same api as well, so one can do:

import stored_messages
stored_messages.add_message(request, stored_messages.INFO, 'Hello!')

If you want to use standard message levels but persist the messages, just add something like this to the settings:

from django.contrib import messages
STORED_MESSAGES = {
    # persist standard infos and standard errors
    'STORE_LEVELS': (messages.INFO, messages.ERROR,),
}

Iterating the messages will automatically mark them as read (but still persisted):

storage = messages.get_messages(request)
for unread_message in storage:
    # unread_message could be a stored message or a "standard" Django message
    do_something_with(unread_message)

…unless you mark the storage as not used:

storage.used = False

You can mark a stored message as read at any time:

stored_messages.mark_read(request.user, message)

Want to store your messages on Redis instead of your database? Here you go:

STORED_MESSAGES = {
    'STORAGE_BACKEND': 'stored_messages.backends.RedisBackend',
    'REDIS_URL': 'redis://localhost:6379/0',
}
