Rails - Apr 2006 - Model extends and belongs_to another model - problem

I have a model, categories, and another model, subcategories. In my 
current code these have no connection except for the fact that 
categories has_many subcategories and a subcategory belongs_to a 
category. But by necessity, I need to change it so Subcategory extends 
Category; so that I can search both models with one command.

I was hoping it would be as simple as changing Subcategory < 
ActiveRecord::Base to Subcategory < Category, but no such luck. Now I 
get the error:

no such column "category_id" in categories

when the page tries to run:

<% for subcategory in category %>

What am I missing about inheritance? AWD has very little on the subject.

Thanks,

Adam
