Rails - Feb 2010 - Newbie RESTful routing problem, please help!

Hello, on my last post a few weeks ago, all who replied seemed to agree
that the problem I was having was in my routing configuration.  I
decided to read up a bit on rails routing using this article:
http://guides.rails.info/routing.html

I decided to try what the article calls RESTful routing.  So I set my
model:

class Receta < ActiveRecord::Base
end

I set up my controller:

class RecetaController < ApplicationController
  def index

  end

end

And I set up my view (which I generated along with my controller:

<h1>Receta#index</h1>
<p>Find me in app/views/receta/index.html.erb</p>

I then set up my routing in routes.rb as follows:

 map.resources :recetas

I got an error with the following full trace:

`call''

I then tried setting up my routing like this:

map.resources :receta

  And it worked.  Can someone please clarify why with :recetas it
didn''t
work?  What difference does it make to declare a resource with an "s"
at
the end.  Any info will be greatly appreciated.  Thanks in advance.


Note: I removed the default routes for both attempts.

The convention is that controllers are plural, so instead of...

class RecetaController < ApplicationController

you should have...

class RecetasController < ApplicationController

note the plural form of Recetas

your controller should be:

class RecetasController < ApplicationController
  def index
  end
end

not:

class RecetaController < ApplicationController

Try this:

map.resources :recetas, :controller => "receta"
