Here are pretty decent error methods to start with. Dirty Details The error_messages_for method outputs neatly formatted error messages for a given object. The catch is that you need to specify the name of the instance variable here, not the object name itself. Take the following example. text/html 2010-04-09T09:02:17+02:00 Onno Schuit http://tech.solin.eu/doku.php?id=linux:apache_webserver&rev=1270796537&do=diff Apache - Part 1 Installing the Apache webserver is pretty straightforward. Do not use Apache 2.x, but instead rely on Apache 1.3.x. See the php.org website why. (The Apache 2 architecture is just not safe enough for php in production environments). text/html 2009-11-16T22:13:20+02:00 Onno Schuit http://tech.solin.eu/doku.php?id=ror:caching_nested_forms&rev=1258406000&do=diff Normally, using a nested resource's url leads you to the controller of the “embedded” resource. 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+02:00 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. But before we dive into the specifics, first some assumptions: * You've got two or more forms and at least one interface element, let's say a button, to submit all forms. * You are not afraid to use a javascript library. Actually, a specific library: Prototype. * Your forms have unique form elements.

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:
