Module: AutoClearCache

Extended by:
ActiveSupport::Concern
Defined in:
lib/app/models/concerns/auto_clear_cache.rb

Overview

Clear the Rails.cache when this object is saved. This prevents a number of caching issues over time where we've put it in cache, but the update doesn't appear until that cache expires.
