Counterfeit
This gem helps you count somebody's money in your Rails application. It is basically a nice rails-wrapper for Money gem.
Installation
Gemfile:
gem 'counterfeit'
Console:
bundle install
Usage
In your migrations:
create_table(:products) do |t|
t.integer :price_in_cents, :default => 0, :null => false
t.string :price_currency, :limit => 3, :null => false
end
or
create_table(:products) do |t|
t.money :price
end
In your models:
class Product < ActiveRecord::Base
has_counterfeit :price
end
You can specify default currency like this:
has_counterfeit :price, :currency => 'EUR'
Now lets play a little:
product = Product.new
product.price
# => #<Money cents:0 currency:USD>
product.price = 500
product.price
# => #<Money cents:50000 currency:USD>
product.price.exchange_to('EUR')
# => #<Money cents:35491 currency:EUR>
user = User.new
user.balance = Money.new(100000, 'RUB')
user.balance > product.price
# => false
# need moar moneez
