from django.contrib.messages.storage.fallback import FallbackStorage from django.contrib.messages.storage.session import SessionStorage from django.contrib.messages.storage.cache import CacheStorage # Initialize FallbackStorage with SessionStorage and CacheStorage backends storage = FallbackStorage(SessionStorage, CacheStorage) # Add message to storage storage.add_message('warning', 'This is a warning message.') # Retrieve messages from storage messages = storage._get()In this example, FallbackStorage is initialized with SessionStorage and CacheStorage backends. When a message is added to the storage, it will be saved in SessionStorage if it's a warning message and saved in CacheStorage for all other message levels. The messages can then be retrieved from the storage using the `_get()` method. Overall, django.contrib.messages.storage.fallback provides a flexible way to store messages depending on their levels. It allows developers to customize the message storage based on their specific needs.
