Trivial example of a view model using dependency injection to access view context

view_models.rb

class Controller
  expose(:person) { PersonView.new(Person.first, self) }
end

class Decorator
  attr_reader :controller, :object

  def initializer(object, controller)
    @object, @controller = object, controller
  end

  def view
    controller.view_context
  end
end

class PersonView < Decorator
  def profile_link
    view.link_to object.profile
  end
end
