What the error says is you do not have an id column. All tables which back an ActiveRecord Model must include an auto-incrementing primary key, by tradition named 'id'. There are no exceptions to this as far as I know.
If you are making a "join model", then you also have to have an id. The only exception would be a habtm relationship join, which by definition can only have two columns: model_a_id and model_b_id.
