= Conversions
The conversions plugin does a number of things. The core functionality is the unit conversion:
1.miles.to(:kilometres) #=> 1.609344
1.pounds.to(:kilograms) #=> 0.453592
It also adds a class method to ActiveRecord::Base that allows you to define conversion methods for attributes:
class Car < ActiveRecord::Base
conversion_accessor :weight, :internal => :kilograms, :external => :pounds
end
car = Car.new(:weight => 1500)
car.weight_in_pounds #=> 3306.93393
