How to dynamically alter inheritance in Ruby

Question

I would like to dynamically specify the parent class for a class in Ruby. Consider this code:

class Agent
  def self.hook_up(calling_class, desired_parent_c         


        

Answer 1

Look at this

  class MyClass < inherit_orm("Adapter")
  end

And the class selector:

  def inherit_orm(model="Activity", orm=nil)
    orm = Config.orm || orm
    require "orm/#{orm.to_s}"
    "ORM::#{orm.to_s.classify}::#{model}".constantize
  end

So, when instance MyClass it will be inherit from a dynamic class depending of orm and model. Be sure to define both in a module. It work fine in public_activity gem ( selector example ).

I hope to help.. Bye!
