Calling classes in / lib from controller actions

Question

Hi, I'm a little stuck on this. what I'm going to work out is that I have a file called ticket_pdf.rb in the lib / directory, which I plan to generate some PDF invoice files for my application. I want to call a function of this class to create PDF files from my actions with the controller.

ticket_pdf.rb is as follows

class TicketPDF def generate_pdf (purchase) puts "Ticket ID = #{purchase.ID}" end end 

In the action of the controller, I am doing this.

 class Customer::MyController < ApplicationController require 'ticket_pdf' def show ticket = TicketPDF.new end end 

when I try to create such an object, it gives me a 500 error like this.

 uninitialized constant Customer::MyController::TicketPDF 

what am i doing wrong here?

Answer 1

Try

 ticket = ::TicketPDF.new 

You created TicketPDF in the top-level namespace.
