How can I effectively manage cache invalidation in Django?

To manage cache invalidation in Django, you can use signals, custom cache keys, or the built-in cache framework.

What are Django signals and how do they help with cache invalidation?

Django signals allow you to trigger actions when certain events occur, like saving or deleting a model, which can help clear or update the cache.

Can you give me an example of using signals for cache invalidation?

Sure! You can connect a signal to the post_save event of a model to clear the cache whenever a new instance is created.

What about using custom cache keys? How does that work?

Custom cache keys allow you to create unique identifiers for cached data, making it easier to invalidate specific entries when needed.
