module Resourceful
  module Default
    # Contains the definitions of the default resourceful actions.
    # These are made available with the Builder#actions method.
    #
    # These methods are very compact,
    # so the best way to understand them is just to look at their source.
    # Check out Resourceful::Accessors and Resourceful::Callbacks
    # for the documentation of the methods called within the actions.
    #
    # Along with each action is listed the RESTful method
    # which corresponds to the action.
    # The controller in the examples is FoosController,
    # and the id for single-object actions is 12.
