[Rails] Routes problems

Hello.
I have many links like these:
/articles/...
/albums/...
/photos/...
etc.

I need to use the name of the city in the beginning of urls if the
user has choosed it:
/city_name/articles/...
/city_name/albums/...
/city_name/photos/...

But previous links shoul work too (/articles/..., /albums/...)
====

I tried this:

map.articles '/articles/', :controller => "zags", :action =>
"cities", :using_city => 1
map.articles '/:city_url/articles/', :controller => "zags", :action =>
"cities", :using_city => 1

<%= link_to "London articles", articles_path, { :city_url =>
"london", :using_city => 1 } %>

But it does not work.
What should I change?
I know, that I can change one of map names "map.articles", but I want
to use the same route names in my View code.How can I do it?
