The increasing of crime about credit or debit card in 2006-2007 was in the top level. Many methods they did to get your card and any confidential information. Some victims were shocked when they read their billing statement, there's many international transactions occurred or withdrawn their card internationally. Let me explain you about technology hardware what they use (inspired from BBC TV Show about this case).

Let we see how they steal your card information from ATM Machine or Retail Store.

1. They will prepare all tools that they called skimmer, msr and wireless camera.

One quite important feature of this site is a list of members who are currently online. First off this only works if you use ActiveRecord to manage your sessions. To do this you must uncomment the following line in your environment.rb file:

config.action_controller.session_store = :active_record_store
.

rake db:sessions:create
.

member = Member.new( @params[ :member ] )
member = Member.find( :all, :conditions => "screen_name = '#{member.screen_name}' AND password = '#{member.password}'" )
if member != nil
session[ :member_id ] = member.id
redirect_to :action => 'success'
else
redirect_to :action => 'form'
end

def who_is_online
@whos_online = Array.new()
onlines = CGI::Session::ActiveRecordStore::Session.find( :all, :conditions => [ 'updated_at = ?', Time.now() - 10.minutes ] )
onlines.each do |online|
id = Marshal.load( Base64.decode64( online.data ) )
@whos_online << id

When you make an application using ruby on rails, the models will validate input of users, if error, your view will display messages from models with followed official statement like " X errors prohibited this object from being saved ". and "There were problems with the following fields:". Now you think how to change it in your own country language. What i have done is i put the script below in appz_name/app/helpers/application_helper.rb

module ApplicationHelper

def error_messages_for(*params)
options = params.last.is_a?(Hash) ? params.pop.symbolize_keys : {}
objects = params.collect {|object_name| instance_variable_get("@#{object_name}") }.compact
count = objects.inject(0) {|sum, object| sum + object.errors.count }
unless count.zero?
html = {}
[:id, :class].each do |key|
if options.include?(key)
value = options[key]
html[key] = value unless value.blank?
else
html[key] = 'errorExplanation'
end
end
header_message = "Telah Terjadi Kesalahan, Harap Perhatikan Hal-Hal Berikut"
error_messages = objects.map {|object| object.errors.full_messages.map {|msg| content_tag(:li, msg) } }
content_tag(:div,
content_tag(options[:header_tag] || :h2, header_message) << content_tag(:p, 'Daftar error:') << content_tag(:ul, error_messages), html ) else ''
end
end
end

You really have ever thought that "how i can change $ symbol to my country currency's symbol in production mode?", it has been happened to me. Like we have known that we can not modify Action Pack in Production Server, so the alternative is we have to make a helper to solve problem like this. And this what i do:

1. Open appz_name/app/helpers/application_helper.rb
2. Then write this code into it:

module ApplicationHelper

def number_to_currency(number, options = {})
options = options.stringify_keys
precision = options["precision"] || 2
unit = options["unit"] || "Rp."
separator = precision > 0 ? options["separator"] || "." : ""
delimiter = options["delimiter"] || ","

begin
parts = number_with_precision(number, precision).split('.')
unit + number_with_delimiter(parts[0], delimiter) + separator + parts[1].to_s
rescue
number
end
end
end

<%= number_to_currency(@my_money_in_pocket) %>
.

Rp. 50.000,00
.

<%= number_to_currency(@my_money_in_pocket, :unit => "Rp. ", :precision => 2, :separator => ",", :delimiter => ".") ) %>
