has_money¶ ↑

In your ActiveRecord model:

class Order < ActiveRecord::Base
  has_money :default_price
end

Defines methods :default_price_in_dollars and :default_price_in_dollars= which make life easier when building forms.

> Order.new :default_price_in_dollars => '10.00'
=> #<Order default_price: 1000>

If you want to store your prices in cents but offer a form input that rounds to the nearest dollar

> order = Order.new :default_price_in_dollars_without_cents => '9.99'
=> #<Order default_price: 1000>
> order.default_price_in_dollars_without_cents
=> '10'
