How do I use cache keys in Ruby on Rails?

In Ruby on Rails, cache keys are used to uniquely identify cached content. You can use them to store and retrieve cached data efficiently.

Can you give me an example of how to implement cache keys?

Sure! You can use the cache method in your views like this: cache(['user', user.id]) do followed by the content you want to cache.

What happens if the cache key changes?

If the cache key changes, Rails will treat it as a new cache entry, and the old cached content will not be retrieved.

Are there best practices for naming cache keys?

Yes, it's best to use a consistent naming convention, include relevant identifiers, and consider versioning to avoid conflicts.
