Rails 4中的response_to pdf

Question

I have an index controller action which responds to the pdf format which looks something like

class ProposalsController < ApplicationController
  respond_to :pdf, :html
  def index
    @proposals = Proposal.all

    respond_with @proposals do |format|
      format.html
      format.pdf
    end
  end
end

Proposal has a to_pdf method which creates Prawn::Document . How can I loop over each of the propsals, grab it's PDF, append it to a newly created PDF, and then render that in the browser via respond_with ?

One can use rails API to create a personalized renderer. In fact, the book Crafting Rails 4 Applications by José Valim show you how to create personalized PDF renderer in the first chapter.
