I have a wonderful question, that I'm sure someone has come across before.



I have some classes that are inheriting from ApplicationRecord and ApplicationRecord inherits from ActiveRecord::Base.



Lets call my classes Post, Comment, Author.



Now I have multiple concerns for each of these things which have inclusions. So that I do not have to hard code in each of the concerns I have a ConcernDirectory.



The call to it essentially runs each of the concerns for the model.



ConcernDirectory.inclusions(self).each 


If I have this in each model everything works fine.



However if I put this into the parent (ApplicationRecord) it no longer works.



When I run it in ApplicationRecord, self points to ApplicationRecord(abstract). How do I get the call from ApplicationRecord to refer to the child from which the call came?



eg.



post = Post.new


when it instantiates its parent class's



--------------.is_a?(::Post) 


would be true from the ApplicationRecord.



What is -----------?



Thanks for the help!

  • and btw, why not include everything directly into ApplicationRecord and go the complex way of having something that does the inclusion?
