Maybe get values from an object. Wrap one object, but check if an alternate one has better data first. In this case, we wrap a user object, but for the methods we specify we can check the profile object for data before falling back to the user.

multiwrapper.rb

  require 'delegate'
  class SpecialFormatter < SimpleDelegator

    def initialize(user, profile)
      super(user)
      @profile = profile
    end
    attr_reader :profile

    def self.maybe(*names)
      options = names.last.is_a?(Hash) ? names.pop : {}
      accessor = options.fetch(:from)
      names.each do |name|
        define_method(name) do
          from = self.send(accessor)
          (!from.nil? && from.respond_to?(name) && from.public_send(name)) || __getobj__.public_send(name)
        end
      end
    end

    maybe :first_name, :last_name, :email, from: :profile
  end
