I’m working on a very simple mail merge system with Ruby on Rails. I have 2 models (members and letters).

First I create a html-formatted letter with some special fields (like {NAME}, {ADDRESS} or {CITY}.

Then, I must generate a PDF with one letter per member. So, if I have 100 members in the database, the PDF must have 100 letters, each one customized (replacing the special fields with the data in the database).

I know how to create the letters in html, but I don’t know how to generate the PDF. Can you help me with that? I know there are some gems to create PDFs, but I don’t know how to add the letters on different pages.

Thanks for your help!

    I have used Prawn to generate PDFs and it sounds like it would work for you. There’s a wiki article on using Prawn with Rails.

    The go_to_page method will let you position elements on a particular page after you have used add_pages to create them.
