How do I configure cache store in Ruby on Rails?

To configure the cache store in Ruby on Rails, you can set it in the config/environments/*.rb files. For example, in config/environments/production.rb, you can use:

config.cache_store = :memory_store, { size: 64.megabytes }

You can also use other stores like :file_store, :mem_cache_store, or :redis_cache_store.

What are the different types of cache stores available?

Rails supports several cache stores, including:

• :memory_store: Stores data in memory.
• :file_store: Stores data in files on disk.
• :mem_cache_store: Uses Memcached for caching.
• :redis_cache_store: Uses Redis for caching.

You can choose based on your application's needs.

How can I clear the cache?

You can clear the cache in Rails by using the following command in the Rails console:

Rails.cache.clear

This will remove all cached entries.

Is there a way to set cache expiration?

Yes, you can set cache expiration by using the expires_in option when writing to the cache. For example:

Rails.cache.write('key', 'value', expires_in: 10.minutes)

This will expire the cache entry after 10 minutes.
