-module ActiveModel
- # This API is for Rails' internal use and is not currently considered 'public', so
- # it may change in the future without warning.
- #
- # It creates configuration attributes that can be inherited from a module down
- # to a class that includes the module. E.g.
- #
- # module MyModel
- # extend ActiveModel::Configuration
- # config_attribute :awesome
- # self.awesome = true
- # end
- #
- # class Post
- # include MyModel
- # end
- #
- # Post.awesome # => true
- #
- # Post.awesome = false
- # Post.awesome # => false
- # MyModel.awesome # => true
- #
- # We assume that the module will have a ClassMethods submodule containing methods
- # to be transferred to the including class' singleton class.
- #
- # Config options can also be defined directly on a class:
- #
- # class Post
- # extend ActiveModel::Configuration
- # config_attribute :awesome
- # end
- #
- # So this allows us to define a module that doesn't care about whether it is being
- # included in a class or a module:
- #
- # module Awesomeness
- # extend ActiveSupport::Concern
- #
- # included do
- # extend ActiveModel::Configuration
- # config_attribute :awesome
- # self.awesome = true
- # end
- # end
- #
- # class Post
- # include Awesomeness
- # end
- #
- # module AwesomeModel
- # include Awesomeness
- # end
