Module: MetaRuby::DSLs::FindThroughMethodMissing

Defined in:
lib/metaruby/dsls/find_through_method_missing.rb

Overview

Common definition of #respond_to_missing? and #method_missing to be used in conjunction with find_through_method_missing and has_through_method_missing?

Examples:

resolve ‘event’ objects using method_missing

class Task
   # Tests if this task has an event by this name
   #
   # @param [String] name
   # @return [Boolean]
   def has_event?(name)
   end

   # Finds an event by name
   #
   # @param [String] name
   # @return [Object,nil] the found event, or nil if there is no
   #   event by this name
   def find_event(name)
   end

   include MetaRuby::DSLs::FindThroughMethodMissing

   # Check if the given method matches a find object
   def has_through_method_missing?(m)
     MetaRuby::DSLs.has_through_method_missing?(
        self, m, '_event' => :has_event?) || super
   end

   # Check if the given method matches a find object
   def find_through_method_missing(m, args)
     MetaRuby::DSLs.find_through_method_missing(
        self, m, args, '_event' => :find_event) || super
   end
end
