Facade-based presenters with minimal assumptions. This library contains utilities for setting up presenters for data classes for things like web services, logging output, etc.
It is intended to be dead-simple by default, returning a Hash containing only the attributes you have intentionally exposed from the subject.
The most basic usage looks something like this:
require 'presentatbility' # lib/acme/presenters.rb module Acme::Presenters extend Presentability presenter_for Acme::Widget do expose :sku expose :name expose :unit_price end end # lib/acme/service.rb class Acme::Service < Some::Webservice::Framework get '/api/widgets/<sku>' do |sku| widget = Acme::Widget.lookup( sku ) content_type 'application/json' representation = Acme::Presenters.present( widget ) return representation.to_json end end
Note that Presentability doesn't do any encoding for you, or infer anything, or require that you alter your data classes. It's just a collection of Facades for your data objects that return a limited representation of their subjects.
More details can be found in the docs for the Presentability module, and in Presentability::Presenter.
$ gem install presentability
