BlanketCachekey

Provides a rails cache key for caching data that should be invalidated whenever any ActiveRecord instance of a specific type is created, updated, or destroyed.

Installation

Add this line to your application's Gemfile:

gem 'blanket_cachekey'

And then execute:

$ bundle

Or install it yourself as:

$ gem install blanket_cachekey

Usage

Include BlanketCachekey within your ActiveRecord class:

class Bar < ActiveRecord::Base

  include BlanketCachekey

end

Now Bar has a blanket_cachekey method which is updated whenever any instance of Bar is created, updated, or destroyed. This key can be used as part of a cache key.

= cache ['bars_selector', Bar.blanket_cachekey] do
  f.input :bars, collection: Bar.all

Now whenever any Bar is created, updated, or saved, the cache fragment above will be regenerated on the next hit.
