Module: RailsNamedCache::RailsExt

Defined in:

lib/rails_named_cache/rails_ext.rb

Overview

Prepended onto the Rails singleton class so Rails.cache takes an optional store name.

This is the only monkey patch in the gem.

Rails.cache          # => the default Rails cache, untouched
Rails.cache(:memory) # => the store registered as :memory

Instance Method Summary

• #cache(*name) ⇒ ActiveSupport::Cache::Store

  Splat rather than a nil default, so Rails.cache(name) with a nil name raises instead of quietly reading the default store.
