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"
