[Ruby] Inheritance of a class instance var from a module to classes
So, I wrote an extension to Rails' ActiveRecord that works well, in fact too well and I need to put some constraints on it (a few arrays of no-no words, and some methods with various combinations of those arrays). I need those constraints to be able to be added to or overwritten by the inherited models, but I would like to have some defaults that should sufficiently cover most models.
I'm ashamed to admit it but I've discovered today that over time relying on the auto-magic I've gotten rusty on my Ruby fundamentals.
So,
using this pattern module ClassLevelInheritableAttributes def self.included(base) base.extend(ClassMethods) end module ClassMethods def inheritable_attributes(*args) @inheritable_attributes ||= [:inheritable_attributes] @inheritable_attributes += args args.each do |arg| class_eval %( class << self; attr_accessor :#{arg} end ) end @inheritable_attributes end def inherited(subclass) @inheritable_attributes.each do |inheritable_attribute| instance_var = "@#{inheritable_attribute}" subclass.instance_variable_set(instance_var, instance_variable_get(instance_var)) end end end end
I can do exactly what I want! (yay) But, I would have to open up ActiveRecord to add inheritable_attributes, and I'm told coders who monkey patch are literally Hitler.
So, I've mocked up some classes and modules that pretty closely match what I wish worked and I was hoping someone could help me turn it into working code.
class Foo end module Terms class << self @hello = ["Hi"] end end module Greet include Terms module ClassMethods def say_hi @hello end end end Foo.send(:include, Greet) class Fizz < Foo class << self @hello += %w(there, fizz) end end class Buzz < Foo # class << self @hello += %w(, buzz buzz) # end end class Boop < Foo end p Fizz.say_hi p Buzz.say_hi p Boop.say_hi
