This is a gem that provides Ruby objects with the capability of object caching. This gem is framework-agnostic, so it can be used in all the types of Ruby applications.
gem install object_cacheable
In Gemfile, write:
In your application, write:
In your application, there must be a directory called conf or config (either will work) that contains a file called cache_configs.yml.
Object that wants to be cached must include Cacheable,
class Person include Cacheable end
and implement the method:
def self.fetch(attributes,args) # Your code to do the real object retrieval here # It can be database call, webservices call or complex object builder # The first argument attributes is an array of attribute names that we want to retrieve the object by # The second argument args is an array of values of the attributes # for example Person.fetch(['first_name', 'last_name'], ['Linh', 'Chau']) # But the combinations of attributes must be able to identify a unique object end
When a Class includes Cacheable and defines the method "fetch", it's instances will become cacheable, and all the cache operations will be handled by the module Cacheable.
