PG-2-JSON-2-PDF Generator

Introduction

This is a simple Postgres to JSON to PDF Generator. It contains two scripts pg2json.rb and json2pdf.rb, each converting from a Postgres table to a JSON file, and from a JSON file to PDF respectively.

Dependencies

These scripts expect the system to have atleast Ruby 1.8 installed. No need to install any other rubygems as the gems are already included and here.

PG2JSON

pg2json.rb converts a Postgres table to a JSON file. Things that needs to be done:

  1. Edit ./database.yml and change the database, tablename and column_as_filename values
  2. Add username and/or password if applicable.

Then, just run:

$ ruby pg2json.rb

The script will read the specified table, and output a data.json.

JSON2PDF

json2pdf.rb converts the data.json to PDF files.

YOU NEED TO CUSTOMIZE json2pdf.rb TO SUIT YOUR OWN PDF GENERATION!

For a sample run, if you have the sample data.json, just run:

$ ruby json2pdf.rb

For your own customization, you have to edit out inside this block:

Prawn::Document.new do
 # your customization here
end

How it works is similar to a word document; it has somekind of carrot that you can control. The line text row['name'], :size => 25, :align => :center will render a text from column name. Change name to your specified column.
