Rails 3.1 - How to redirect properly with custom routes

I have a Pages model with field 'customURL'. I can do page#show at '/:customurl'. but because i've defined page show that way in routes, my create action now does a redirect on success to the wrong route. What should I change to most cleanly fix the redirect properly to point to '/:customurl' on save?

controller:

def create
  @page = Page.new(params[:page])

    if @page.save
      format.html { redirect_to page_url, notice: 'Page was successfully created.' }
      format.json { render json: @page, status: :created, location: @page }
    else
      format.html { render action: "new" }
      format.json { render json: @page.errors, status: :unprocessable_entity }
    end
  end
end

routes:

resources :pages
...
get "/:customURL" => "pages#show"

Thanks!

In routes.rb, you can add magic helpers.

get "/:customURL" => "pages#show", :as => :custom

Then in your controller

format.html { redirect_to custom_url(@page. customURL), notice: ... }

Now, "/:customURL" will need to be last in your routes.rb, routes are greedy, the first to match will get it. So if you have something like "/bob" and you have a controller listening at "/bob", the controller will get it before the pages controller.
