mongoid_money

Be aware! This gem currently requires mongoid to be included in your gemfile as such

gem "mongoid", :git => "git://github.com/mongoid/mongoid.git"

due to a type casting bug introduced in Mongoid version 2.0.0. The fix has not been released to rubygems.org yet.

Description

A simple gem that creates a Money datatype for Mongoid.

Include the gem in your Gemfile

gem 'mongoid_money'

Now you can do things in your Mongoid documents like

field :price, :type => Money, :default => 9.99.dollars

or

field :price, :type => Money, :default => 10.dollars

or

field :price, :type => Money, :default => 99.cents

All Money values are converted and stored in mongo as cents.

You can also query against your Money fields. Just do the following:

Item.where(:price => 5.dollars)

or

Item.where(:price.gt => 10.dollars)

If you want to store fractions of a cent you can also adjust the multiplier (default is 100):

10.123.dollars # => 10.12
Money.multiplier = 1000
10.123.dollars # => 10.123

Commit and push until you are happy with your contribution
Make sure to add tests for it. This is important so I don't break it in a future version unintentionally.
Please try not to mess with the Rakefile, version, or history. If you want to have your own version, or is otherwise necessary, that is fine, but please isolate to its own commit so I can cherry-pick around it.
