Thanks!
Caching in Rails
Rails has wonderful inbuilt caching methods. This is how i implemented caching for a particular action. Requirement : Cache a page for 12 hours. After 12 hrs Caching must expire. before_filter :clear_cache caches_action :index, :layout => false def index #code # Write expiry time to cache (12 hours) Rails.cache.write('expiry_time', Time.now + 12.hours) end def clear_cache #Fetch time from cache and check with current time t = Rails.cache.fetch('expiry_time') || Time.now t = Time.parse(t) if t.is_a?(String) # Expire action if current time > Cached time expire_action :action => :index if Time.now > t end Thanks!
