将原始html写入Rails中的响应对象（使用ActionDispatcher :: Response）

Question

How to write the response from the controller using the ActionDispatch::Response object. There seems to be no api that does http://api.rubyonrails.org/classes/ActionDispatch/Response.html .

The below code works which does not use any view. Is the same can be achived using a response object. The reason being having a necessity to write some binary data to html(which is required for the the current rails app being written)

class HelloController < ApplicationController
  def index
    render :text => "hello" # want to use ActionDispatch::Response object instead of this
  end
end
