module Authlogic
  module AuthenticatesMany
    # An object of this class is used as a proxy for the authenticates_many
    # relationship. It basically allows you to "save" scope details and call
    # them on an object, which allows you to do the following:
    #
    #   @account.user_sessions.new
    #   @account.user_sessions.find
    #   # ... etc
    #
    # You can call all of the class level methods off of an object with a saved
    # scope, so that calling the above methods scopes the user sessions down to
    # that specific account. To implement this via ActiveRecord do something
    # like:
    #
    #   class User < ActiveRecord::Base
    #     authenticates_many :user_sessions
    #   end
    class Association
      attr_accessor :klass, :find_options, :id

      # - id: Usually `nil`, but if the `scope_cookies` option is used, then
      #   `id` is a string like "company_123". It may seem strange to refer
      #   to such a string as an "id", but the naming is intentional, and
      #   is derived from `Authlogic::Session::Id`.
      def initialize(klass, find_options, id)
        self.klass = klass
        self.find_options = find_options
        self.id = id
      end

      [:create, :create!, :find, :new].each do |method|
        class_eval <<-"end_eval", __FILE__, __LINE__
          def #{method}(*args)
            klass.with_scope(scope_options) do
              klass.#{method}(*args)
            end
          end
        end_eval
      end
