klass()

Returns the class for the macro.

composed_of :balance, class_name: 'Money' returns the Money class has_many :clients returns the Client class

class Company < ActiveRecord::Base
  has_many :clients
end

Company.reflect_on_association(:clients).klass
# => Client

Note: Do not call klass.new or klass.create to instantiate a new association object. Use build_association or create_association instead. This allows plugins to hook into association object creation.
