Cached Attributes

Super simple caching for Ruby

class Product
  attr_cached :orders_count

  def orders_count
    # ...
  end

end

Choose when to use the cached value

product.orders_count        # not cached
product.cached_orders_count # cached

Force a re-cache [master]

product.cache_orders_count!

Installation

Add this line to your application’s Gemfile:

gem 'cached_attributes'

Works with any ActiveSupport cache store. For Rails, Rails.cache is used by default.

Set the cache store with:

CachedAttributes.cache = ActiveSupport::Cache::MemoryStore.new
