HasCacheKey -- automatic cache key management For Rails

Allows you describe cache keys in the models, and provides automatic expiration

Installation

Add this line to your Gemfile:

gem 'has_cache_key'

Usage

Define cache_keys in your model

class Listing < ActiveRecord::Base
  # Default cache key for the listing view
  has_cache_key :id
  # A cache key for the home page of category in location
  has_cache_key [:location_id, :category_id], name: :category_in_location_home_page
end

To get a cache key in you can use one of the following:

# Default cache key
@listing.cache_key

# A cache key
@listing.cache_key(:category_in_location_home_page)

# A cache key without a listing instance:
Listing.cache_key(:category_in_location_home_page, category_id: 10, location_id: 10)

Your cache keys will be automatically updates after_save and after_destroy according to the attribute changes.
