Quick Tip: Route Associations

Posted by Curtis Miller Curtis Miller

Are you used to writing your routes like this?

map.resources :notes do |notes|
  notes.resource  :author
  notes.resources :comments
  notes.resources :attachments

Don't fret, there may be hope for you yet. For these simple routes you can use the has_one or has_many route association options.

  • has_one – use it for a singleton resource
  • has_many – use it for plural resources

Refactored routes

map.resources :notes, :has_one => :author, :has_many => [:comments, :attachments]

Give it a try!

Keep in mind I said simple. If you're doing something more complex they might not be the best choice.
