E.g: map.resources :guests, :has_many => :registrations Produces: guest_registrations GET /guests/:guest_id/registrations(.:format) {:controller=>"registrations", :action=>"index"} POST /guests/:guest_id/registrations(.:format) {:controller=>"registrations", :action=>"create"} new_guest_registration GET /guests/:guest_id/registrations/n… text/html 2009-11-16T21:12:57+01:00 Onno Schuit http://tech.solin.eu/doku.php?id=webdev:submitting_multiple_forms_at_once&rev=1258402377&do=diff Sure, you should avoid building multiple forms on one page. And no, technically speaking it is not possible to submit more than one form at a time. So, we're gonna cheat.

The most immediately useful type of caching is action caching (because you can combine it with authentication). You can just use call caches_action in your controller file, giving the action to be cached as an arugment: text/html 2009-11-13T17:29:52+01:00 Onno Schuit http://tech.solin.eu/doku.php?id=ror:how_to_prevent_asset_caching&rev=1258129792&do=diff How To Prevent Caching Rails has some pretty strong caching mechanisms.
