Use WickedPDF to make PDFs in Rails

Setup
1 Add these two gems to the gemfile
  # PDFs
  gem 'wicked_pdf'
  gem 'wkhtmltopdf-installer', github: 'vovayartsev/wkhtmltopdf-installer-ruby', branch: 'master'
2 Make an init file and load the wkhtmltopdf binary path
  require 'wkhtmltopdf_installer'
  WickedPdf.config = { exe_path: WkhtmltopdfInstaller.wkhtmltopdf_path }
Usage
1 Make a controller
  class PdfController < ApplicationController

    # /pdf.pdf
    def index
      respond_to do |format|
        @pdfs = PDF.all
        format.html

        format.pdf do
          render pdf: "sample_file",
                 orientation: 'Portrait',
                 page_size: 'A4',
                 layout: false,
                 disable_javascript: true,
                 grayscale: true,
                 lowquality: true,
                 no_background: true
        end

      end
    end

  end
2 Make views that will be PDF friendly

  doctype html
  html
    head
      meta charset='utf-8'
    body
      - @pdfs.each |pdf|
