Routing problem when using :format

Rails
1

Using edge rails, latest revision.

routes.rb:
map.connect ‘:controller/:action/:id.:format’
map.connect ‘:controller/:action/:id’

When I enter a url such as http://localhost:3000/player/genres
everything works fine, but when I enter /player/genres.xml I get a
routing error. I have both a genres.rhtml and genres.rxml in my
/app/views/player folder. Do I need to something different to my
routes.rb configuration?

This is my player_controller.rb
def genres
@genres = Genre.tree

respond_to do |type|
  type.html
  type.xml
end

end

From the log:
Processing ApplicationController#index (for 127.0.0.1 at 2006-12-20

This:

/player/genres.xml

does not match this:

:controller/:action/:id.:format

If you want that, you have to define a route like:

:controller/:action.:format

See the difference?

Or just use map.resources to have this all done for you. But only if
you are willing to do it all in a RESTful way.

:controller/:action.:format

Really? I was reading the weblog on ruby on rails and DHH left this
note under the “Formats and responds_to” section
(Ruby on Rails — Rails 1.2: Release Candidate 1)

All new applications will have one additional default route:
map.connect ‘:controller/:action/:id.:format’. With this route
installed, imagine the following example:

class WeblogController < ActionController::Base
def index
@posts = Post.find :all
respond_to do |format|
format.html
format.xml { render :xml => @posts.to_xml }
format.rss { render :action => “feed.rxml” }
end
end
end
GET /weblog # returns HTML from browser Accept header
GET /weblog.xml # returns the XML
GET /weblog.rss # returns the RSS

I thought that :id only matched if it is specified but will default
without if necessary. I also have an index action doing /player and
/player.xml, but resulting in the same problems (/player.xml gives a
routing error). I am using REST for my model classes, but the player
isn’t a model and doesn’t CRUD.

Since I have two actions in the player_controller index and genres,
what route would I need to satisfy both /player.xml and
/player/genres.xml as well as /player and /player/genres? It seems
that by using map.connect “:controller/:action.:format” I can do
/player/genres.xml but not /player.xml, though /player/index.xml seems
to work.

It would seem like map.connect ‘:controller/:action/:id.:format’ would
be correct, but it doesn’t seem to work. Shouldn’t the defaults => {
:action => “index”, :id => nil } be used in the absence of :action or
:id?
