I would like to provide Atom feeds in response to different actions.  
I am aware that eg map.resources :posts helps me generate a feed  
as a request for /posts.:format, but as I am getting into problems,  
I see that I do not have the full understanding of what is going on.

I would like to do the same (but with a different dataset) for other  
actions such as /posts/today or /posts/yesterday.

For instance, I have created app/views/posts/today.atom.builder file,

and in today.html.erb view I put  
\<%= auto\_discovery\_link\_tag :atom, url\_for(:action =\> ‘today’) %\>

but clicking on the feed icon in Firefox only reloads the html page,  
while explicitly requesting posts/today.atom produces:

ActionController::RoutingError (No route matches “/pots/today.atom”  
with {:method=\>:get})

What am I missing? Should I specify a new named route?

```

Do your actions define a response for atom requests in a respond\_to  
block ?

Currently it looks like:

def today  
# load @posts…  
respond\_to do |format|  
format.html  
format.atom  
end  
end

Have you included your additional methods in your routes.rb, as in

map.resources :posts, :collection =\> { :today =\> :get, :yesterday  
=\> :get }

? That should do the trick.

Also, I think the url\_for you’re using in auto\_discovery\_link\_tag  
lacks the format parameter; I think you can use

formatted\_today\_posts\_url(:atom)

and

formatted\_yesterday\_posts\_url(:atom)

instead.

Thank you, the :collections parameter to map.resources is  
what it takes. And it gives the formatted\_\* helpers.  
Now the API docs are more clear :).
