Relating Namespaced Models

I am dealing with a large project. I use a lot of STI and therfore have a lot of models. I'd like to use namespaces to help organize my models but am having trouble getting started.

I have a base model Term::Base located in /app/models/term/base.rb:

class Term::Base < ActiveRecord::Base   set_table_name "terms" end

I have a non-namespaced client model:

class Client < ActiveRecord::Base   has_many :terms, :class_name => "Term::Base" end

When I try to access a client's terms, i get:

Client.find(1).terms

It works if I "unnamespace" my Term::* models by putting them in /app/models/ and removing the Term:: prefixes and of course removing the :class_name => "Term::Base" from the association.

Any ideas fellas?

I had stale data in my terms table. Clearing it out was the solution.
