Best way to implement Categories and Subcategories with flexible depth in Rails?

I have a Category and Subcategory models in my project. I would like to have many sub-levels in a flexible way. I thought making a self referential "parent" foreign key but I'm not quite sure how to do it. Any ideas? Thanks!
