Django's message framework provides one-time notifications to users. I use messages.success(), messages.error(), messages.warning(), and messages.info() to add messages. Messages persist across redirects and are displayed once. I configure message storage backend in settings—session-based is default. In templates, I iterate over messages to display them. For AJAX, I return messages in JSON. The framework works seamlessly with forms and generic views. This gives users feedback on their actions without manual session management.
