                Step of how to connect to host database from Docker network
              
          
    Connect to host database


Create new database user with password for docker.
Configure postgresql.conf to listen for connection from docker network which usually is 172.17.0.0/16. The file's usually located at /usr/local/var/postgres/postgresql.conf for Mac OS X.

Example, add this entry into postgresql.conf file.
listen_addresses = '172.17.0.0/16, localhost'
	function pluck (arrayOfObject, property) {
	return arrayOfObject.map(function (item) {
	return item[property];
	});
	};
	ActiveRecord::Base.transaction do
	100.times do \|i\|
	Item.create({
	name: "item #{i + 1}"
	})
	end
	end
	def find_mismatch_value_between_hash(a, b)
	pivot_hash = a
	another_hash = b

	result_hash = {}

	pivot_hash.keys.each do \|k\|
	pivot_value = pivot_hash[k]
	another_value = another_hash[k]
	# gem install ascii_charts # if necessary
	require 'ascii_charts'
	require 'benchmark'
	require './test.rb'

	include Benchmark

	class Runner

	def initialize
	@value = rand(10)
	@name = "Mr. #{@value}_#{rand(100)}"
	end
	end

	a = Array.new(10).collect { \|e\| e = A.new }
