Create PDFs using HTML+CSS. Uses wkhtmltopdf on the back-end which renders HTML using Webkit.
You need to install these gems mentioned below :
gem install pdfkitgem install wkhtmltopdf-binary
Than need to add this line into application.rb :
config.middleware.use PDFKit::Middleware, :print_media_type => true
Now In View you need to add content or whatever you wants to use :
download_pdf.html.erb
<H1>PDFKit works awesome</H1>
This is you HTML data and going to be convert in pdf
Than in the controller we need add this:
class HomeController < ApplicationController
def download_pdf
html = render_to_string(:action => '../home/download_pdf', :layout => false)
pdf = PDFKit.new(html)
send_data(pdf.to_pdf)
end
end
Than you need to add this link to download pdf or you can change as per your conditions :
<p id="pdf_link">
<%= link_to "Download (PDF)", home_download_pdf_path(:format => "pdf") %>
</p>
