I just updated the beta gems. Execute the following and you''ll be running them: gem update -s http://gems.rubyonrails.org ...they include a bunch of additional fixes and features. Most prominently perhaps are the new rich has_and_belongs_to_many associations that allow you to have additional attributes in the join tables: Added HasAndBelongsToManyAssociation#push_with_attributes(object, join_attributes) that can create associations in the join table with additional attributes. This is really useful when you have information that''s only relevant to the join itself, such as a "added_on" column for an association between post and category. The added attributes will automatically be injected into objects retrieved through the association similar to the piggy-back approach: post.categories.push_with_attributes(category, :added_on => Date.today) post.categories.first.added_on # => Date.today NOTE: The categories table doesn''t have a added_on column, it''s the categories_post join table that does! -- David Heinemeier Hansson, http://www.basecamphq.com/ -- Web-based Project Management http://www.rubyonrails.org/ -- Web-application framework for Ruby http://macromates.com/ -- TextMate: Code and markup editor (OS X) http://www.loudthinking.com/ -- Broadcasting Brain

My past foray into ActiveRecord faltered on has_and_belongs_to_many. I guess I didn''t know what I was doing and didn''t have enough incentive to learn. Now I''m creating a Rails app that has a many-many relationship with additional attributes. If I''m not using the beta gem, how do I manage the attributes in a relationship table? Any good idioms? Gavin
> If I''m not using the beta gem, how do I manage the attributes in a > relationship table? Any good idioms?Then you do it by hand. Like I was doing with Basecamp. Have a service layer of some kind that''s just calling vanilla SQL. You _really_ don''t want to do that, though. Not when an Active Recordish approach is now available. -- David Heinemeier Hansson, http://www.basecamphq.com/ -- Web-based Project Management http://www.rubyonrails.org/ -- Web-application framework for Ruby http://macromates.com/ -- TextMate: Code and markup editor (OS X) http://www.loudthinking.com/ -- Broadcasting Brain

I believe those messages are simply output from the automatic RDoc''ing of the source code that happens when you''re installing gems. -- Regards, John Wilger ----------- Alice came to a fork in the road.
