Rails 3.2 multiple databases with DB-Charmer, Quickstart

Currently, to support rails 3.1 til 3.2.3, we need to install latest version (1.7.1)

gem 'db-charmer', '>= 1.7.1', :require => 'db_charmer'

Assume that we have two database server at 192.168.1.14 and 192.168.1.15

	(defn mark [xs idx]
	"Iterate over the xs with each j step of (idx * idx + (j * idx))
	For each element of step, mark them false (a.k.a not a prime number)"
	(loop [arr xs
	j 0]
	(let [step (+ (* idx idx ) (* j idx))]
	(if (< step (count arr))
	(recur (assoc arr step false) (inc j))
	arr))))

	This will format python datetime as a string to be used within jinja conditionals for comparing current date to article date using pelican app.

	1. Create a file named jinjaext.py
	2. paste the following snippet

	def convertdate(datetime, format='%a-%d-%m-%Y'):
	return datetime.date().strftime(format)

	3. Add the following line to your config file

	#!/usr/bin/env python

	# require lame http://lame.sourceforge.net
	import sys
	import os
	import re
	import subprocess

	path = sys.argv[1:][0]
