The previous post made use of the Django messages framework to display a one-time message after an HTTP redirect.
Using the messages framework is simple. First, as explained in the docs, adjust your settings file:
- ‘django.contrib.messages’ is in INSTALLED_APPS
- MIDDLEWARE_CLASSES contains ‘django.contrib.sessions.middleware.SessionMiddleware’ and ‘django.contrib.messages.middleware.MessageMiddleware’
- TEMPLATE_CONTEXT_PROCESSORS contains ‘django.contrib.messages.context_processors.messages’
You can now use the framework in a view:
This file contains bidirectional Unicode text that may be interpreted or compiled differently than what appears below. To review, open the file in an editor that reveals hidden Unicode characters.

| from django.contrib import messages | |
| # within a view method | |
| messages.add_message(request, messages.INFO, 'This message will appear after the redirect!') |
And display it within a template:
