Deep integration of CanCan into ActiveAdmin

	# blog post:

	# Before using this initializer, you must set up Cancan. First, add the gem to your Gemfile:
	#
	# gem 'cancan'
	#
	# Next, generate and edit an Ability class:
	#
	# rails generate cancan:ability

Active Record

É um design pattern que o Rails implementa a partir da gem ActiveRecord.

Serve para conectar a camada Model da aplicação com tabelas do database, para assim criar um modelo de domínio persistível, onde a lógica (Model) e dados (BD) são apresentados em uma única solução.

Já persiste no BD:

This is my gist that show how we can use CanCan with ActiveAdmin and store permissions in database.

	# config/initializers/active_admin.rb

	ActiveAdmin.setup do \|config\|
	config.current_user_method = :current_user
	config.authentication_method = :authenticate_user!
	config.before_filter :admin_role_filter
	end


	# Adding all recource names to Permissions table after ActiveAdmin is loaded

A intenção era só simplificar e ganhar todos os métodos sem precisar fazer muito, é muito simples fazer em uma classe desprendida do ActiveRecord

	module Searchable
	included do
	scope :gender, ->(gender) { where(:gender => gender) }
	scope :birth_on, ->(date) { where(:birthdate =>date) }
	scope :birth_before_than, ->(date) { where("#{quoted_table_name}.birthdate < ?", date) }
	scope :birth_after_than, ->(date) { where("#{quoted_table_name}.birthdate > ?", date) }
	scope :profile, ->(profile){ where(:profile => profile) }
	end

	module ClassMethods
