Rails routes with date

My question it's about use a filter by date in the route of a rails application, at the moment I all ready have the rule that match the pattern of the date in the routes.rb file, it's looks like this:

match "itineraries/:day/:month/:year" => "itineraries#index", 
        :constraints => { :year => /\d{4}/, :month => /\d{2}/, :day => /\d{2}/ }
match "itinera开发者_如何学运维ries/new/:day/:month/:year" => "itineraries#new", 
        :constraints => { :year => /\d{4}/, :month => /\d{2}/, :day => /\d{2}/ }

resources :itineraries
match '/:controller(/:action(/:id))'
root :to => "itineraries#index"

That match for example /itineraries/01/01/2011, the problem comes when I generate a route from the resource, for example, itineraries_path(:year=>2011,:month=>1,:day=>1) generate:

/itineraries?day=1&month=1&year2011

instead of

/itineraries/01/01/2011

Is there a way to put the match rule inside the resource mapping?

well, short answer is your route does exists, but it's not named yet (check rake routes to convince yourself) and that's why you can't call it just like that (using itineraries_path)

so, the correct way to do it would be for example:

match "itineraries/:day/:month/:year" => "itineraries#index", 
    :constraints => { :year => /\d{4}/, :month => /\d{2}/, :day => /\d{2}/ },
    :as => "itineraries_date"

(notice the :as part)

now, if you call itineraries_date_path(11,12,1998) it will give you itineraries/11/12/1998
