Money v3 Rails plugin
Money v3 supports rails via
composed_of, which is what you'll want to use if you just have a couple money fields (see the Money gem's README).
If you have a lot of money fields, it gets very un-DRY (WET?). This plugin helps with that. It doesn't really need to be a plugin, even, it's just nice to document and package things as a unit sometimes.
class Widget money :price end
Slightly more custom:
class Widget money :price, :subunit_column => 'price_subunit', :currency_column => 'price_currency_string' end
Slightly more custom, but all over:
Money::Rails.config.subunit_column_ext = 'subunit' Money::Rails.config.currency_column_ext = 'currency_string' # database values are 'price_subunit' and 'price_currency_string' class Widget money :price end
In all cases:
w = Widget.new(:price => "5.00") w.price # => Money.new(500, 'USD')
