Moderation Magic - Work in progress

module ModeratedModel
  extend ActiveSupport::Concern

  included do
    belongs_to :admin_approval
    scope :moderated, where(moderated: true)
    scope :not_moderated, where(moderated: false)
  end

  module ClassMethods
    def moderates(field)
      self.instance_eval do
        before_save do
          # The object can start its life moderated already. This is mostly used for testing or inside RailsAdmin.
          # In this case, we ignore it.
          return true if self.new_record? && self.moderated
          # These 'to_s' are there to guard against a field being changed from nil to ''
          # RailsAdmin does that sometimes
          if self.send("#{field}_changed?") && (self.send("#{field}_was").to_s != self.send("#{field}").to_s)
            self.moderated = false
            AdminApproval.create!(entity_type: self.class.to_s, content: field, moderated: false)
          end

          true
        end
      end
    end
  end
end


# usage (for example, user.rb)

class User < ActiveRecord::Base
  #blahblah
  include ModeratedModel
  moderates :bio
end

Não suporta múltiplos campos, but who cares? 10 min pra fazer, mas eu não preciso disso...
