Rails, Prawn - PDF show up in browser & etc

Question

I\'m trying to understand the Prawn pdf gem.

I was able to make it generate a pdf. Every gem in the gemfile included:

gem \'mysql\', \'~> 2.8.1\'
         


        

Answer 1

How can I force prawn to generate the file in the app/report (or any other selected) folder?

def index
  pdf = Prawn::Document.new
  pdf.text "Hello World"
  pdf.render_file File.join(Rails.root, "app/report", "x.pdf")
end

How can I make the action to generate the file in the browser window and don't save it?

def index
  pdf = Prawn::Document.new
  pdf.text "Hello World"
  send_data pdf.render, :filename => "x.pdf", :type => "application/pdf"
end

How can I make it to save and show up in the browser window?

def index
  pdf = Prawn::Document.new
  pdf.text "Hello World"
  filename = File.join(Rails.root, "app/report", "x.pdf")
  pdf.render_file filename
  send_file filename, :filename => "x.pdf", :type => "application/pdf"
end
