Module: Arturo::FeatureCaching
- Defined in:
- lib/arturo/feature_caching.rb
Overview
To be extended by Arturo::Feature if you want to enable in-memory caching. NB: Arturo’s feature caching only works when using Arturo::Feature.to_feature or when using the helper methods in Arturo and Arturo::FeatureAvailability. NB: if you have multiple application servers, you almost certainly want to clear this cache after each request:
class ApplicationController < ActionController::Base
after_filter { Arturo::Feature.clear_feature_cache }
end
Alternatively, you could redefine Arturo::Feature.feature_cache to use a shared cache like Memcached.
