I am new to rails. I am trying to study the structure of rails. And I am wondering, where is the default action for all the controllers (i.e. index) defined. How does rails know that when no action is defined in URL it just loads index as the default action? I assume that this must be in some of the libraries, but anybody who could tell me where. Thanks a lot. :)

Thanks a lot. :) If you're looking at RESTful rails, its just versions of GET, PUT, POST, DELETE requests: Method URL path Action Helper GET /people index people_url GET /people/1 show person_url(:id => 1) GET /people/new new new_person_url GET /people/1;edit edit edit_person_url(:id => 1) PUT /people/1 update person_url(:id => 1) POST /people create people_url DELETE /people/1 destroy person_url(:id => 1) Browsers cannot issue an http DELETE, so Rails fakes this out with a POST request with an additional hidden parameter named '_method' whose value is 'delete'. When Rails receives a _method parameter, it ignores the real http method, and substitutes the value of _method as the request type. I'd list the reference back to the site I poached this from if I could remember what it was.

I believe the default is set in: C:\ruby\lib\ruby\gems\1.8\gems\actionpack-2.0.2\lib\action_controller \resources.rb, but... You better really know what you are doing if you muck with this.

It is now GET /people/1/edit because the semicolon was a bad idea to begin with. Stuff after a semicolon isn't recognized as part of the URL by some browsers. Unfortunately many tutorials still have this old syntax which isn't recognized by Rails 2.
