It depends if you will need to model the join table in the near future, since CakePHP doesn't support multiple primary key fields. If you need, then adding an ID is a must.
If you don't, you could go with both fields as primary keys. But since it doesn't hurt to add an extra ID column, and with it you can prepare if you ever need to query the join table, then I would say add the primary key anyway. -MI --------------------------------------------------------------------------- Remember, smart coders answer ten questions for every question they ask.
