An update to our random_controller for sending HTML to DocRaptor.

random_controller.rb

def show
  @random = Random.find(params[:id])
  respond_to do |format|
    format.html
    format.pdf { doc_raptor_send }
  end
end

def doc_raptor_send(options = { })
  default_options = {
    :name          => controller_name,
    :document_type => request.format,
    :test          => ! Rails.env.production?
  }
  options = default_options.merge(options)
  options[:document_content] ||= render_to_string
  ext = options[:document_type]

  response = DocRaptor.create(options)
  if response.code == 200
    send_data response, :filename => "#{options[:name]}.#{ext}", :type => ext
  else
    render :inline => response.body, :status => response.code
  end
end
