Following this tutorial, I was able to generate PDF's on development mode. My issue is on Heroku as I've tried uploading the repo and but can't get the PDF generation working.
Is this because Heroku doesn't allow serving of PDF files, just like images when using Paperclip? BTW, I didn't upload the exact repo of the tutorial, I just wrote mine from scratch and followed along. Did I perhaps missed some gems?
It's working locally but the PDF generation on Heroku does not.
