🔧 Configure Cache Store

Before using caching in Rails, you need to choose and configure a cache store. In config/environments/development.rb or production.rb, set the cache_store option to something like :memory_store, :file_store, or :mem_cache_store. This determines where Rails will keep your cached data and how long it lasts.

# config/environments/production.rb
Rails.application.configure do
  # Use memory store for small apps or file store for simple setups
  config.cache_store = :memory_store, { size: 64.megabytes }

  # Enable controller caching
  config.action_controller.perform_caching = true
end
