This is a better solution since it avoids the possibility of caching the same info in 2 places (the 2 owners of the habtm association). This patch allows one to call columns and reset_column_information directly from the habtm association: developer = Developer.find 1 developer.projects.columns developer.projects.reset_column_information See the updated patch at http://rails.lighthouseapp.com/projects/8994-ruby-on-rails/tickets/1738-caching-columns-for-has_and_belongs_to_many#ticket-1738-6 After submitting this patch to the Rails core team, upon suggestion I modified the patch to store the cache within the reflection instance of the association.
