Is there a definitive guide on how to create a controller that understands and responds to GET/POST methods ? This does not necessarily mean I''m trying RESTful Web services. Google returned lot of material but most of them is pre-Rails 2.0 or not well explained. Did I miss any obvious document ? -Arun --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

def action if request.post? # Do post stuff elsif request.get? # Do get stuff end end This should be handled with Restful routes, but you said you didn''t want to do it that way.

Ok, that worked! If I want only GET and POST to be handled in a particular manner, how would RESful routes be configured ? Also, a newbie question ... how do I know where the list of variables like "request" accessible in my controller ? -Arun On Apr 21, 10:27 pm, "Ryan Bigg (Radar)" <radarliste...-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote:> def action > if request.post? > # Do post stuff > elsif request.get? > # Do get stuff > end > end > > This should be handled with Restful routes, but you said you didn''t want to > do it that way. > > On Tue, Apr 22, 2008 at 2:55 PM, Arun <arun.gu...-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote: > > > Is there a definitive guide on how to create a controller that > > understands and responds to GET/POST methods ?

I don''t know if this is exactly what you are looking for but I highly
reccomend reading through:
http://caboo.se/doc/classes/ActionController/Base.html
Basically covers the basics of what you can do in a controller. From the
document:
Requests are processed by the Action Controller framework by extracting
the value of the "action" key in the request parameters. This value
should hold the name of the action to be performed. Once the action has
been identified, the remaining request parameters, the session (if one
is available), and the full request with all the http headers are made
available to the action through instance variables. Then the action is
performed.
The full request object is available with the request accessor and is
primarily used to query for http headers. These queries are made by
accessing the environment hash, like this:
def server_ip
location = request.env["SERVER_ADDR"]
render :text => "This server hosted at #{location}"
end

> How do controllers figure out which actions are bound to GET and > POST ?This is a portion of the routes defined in one of my applications: tickets GET /tickets {:action=>"index", :controller=>"tickets"} POST /tickets {:action=>"create", :controller=>"tickets"} new_ticket GET /tickets/new {:action=>"new", :controller=>"tickets"} edit_ticket GET /tickets/:id/edit {:action=>"edit", :controller=>"tickets"} ticket GET /tickets/:id {:action=>"show", :controller=>"tickets"} PUT /tickets/:id {:action=>"update", :controller=>"tickets"} DELETE /tickets/:id {:action=>"destroy", :controller=>"tickets"} Here is a sample link in a view: <%= link_to "Tickets", tickets_path %> The "tickets_path" helper method inside the link maps to this route: POST /tickets {:action=>"create", :controller=>"tickets"} Which of course then maps to the "create" action of the "tickets" controller. If you check the development log after clicking the link you would find this line: Parameters: {"action"=>"create", "controller"=>"tickets"} Note: There is probably some other values in the parms hash, but these two are used for selecting the controller and action. As far as the method used for the request (GET/POST/PUT/DELETE/HEAD) the request object knows that, which Rails has access to (and so do you). Hope this helps clear up some of the voodoo magic.
