Page Object Delegator - an improvement on http://robots.thoughtbot.com/better-acceptance-tests-with-page-objects

page_object_delegator.rb

class PageObjectDelegator
  include Capybara::DSL
  include Rails.application.routes.url_helpers

  def initialize(*args)
    # Create a `path` => `page object model` hash
    @pages = {}
    @pages[foo_bar_path] = FooBarPage.new("Foo Bar")
    @pages[baz_path] = BazPage.new("Baz")
  end

  # Send the named route you wish to check that you're on,
  # e.g. @page_delegator.on_page :foo_bar.
  def on_page?(page)
    @pages[send("#{page}_path")].on_page?
  end

  def method_missing(method, *args)
    # If method not found, delegate to corresponding page object model
    # based on the current page.
    @pages[page.current_path].send(method, *args)
  end
end

Now, whenever you need to call your page object, you can use your page delegator to forward the call to the corresponding page object
