Deprecating composed_of in ActiveRecord
This feature adds a lot of complication to ActiveRecord for dubious
value. Let's talk about what it does currently:
class Customer < ActiveRecord::Base
composed_of :balance, :class_name => "Money", :mapping => %w(balance
amount)
end
Instead, you can do something like this:
def balance
@balance ||= Money.new(value, currency)
end
def balance=(balance)
self[:value] = balance.value
self[:currency] = balance.currency
@balance = balance
end
Since that's fairly easy code to write, and doesn't need anything
extra from the framework, if you use composed_of today, you'll
have to add accessors/mutators like that.
This feature will be removed in Rails 4.
