Rails - Jan 2006 - many-to-many with extra fields

I''m trying to work with a many-to-many relationship, but the join  
table needs to have a is_primary field. What is the best way to work  
with this (adding / changing primary / deleting)? I understand that  
the :through option in Edge Rails can handle this better, but I was  
just wondering if there was a good way to handle this with Rails 1.0.

Thanks,
Kyle

You can create two has_many relationships and an intermediary join model:

In the example above, you have a full join model in the Subscription class.
