[Rails] Issue with passing parameter to action using link_to

Hi,

I have a controller named Users with index action.

def index
    puts "************* #{params[:city]}"
    ...
    ...
end

From the view,
link_to(:city, list_users_with_city_path(:city => city.name))

But when I click on this link, it doesn't prints out anything for the params. All the "*" are being printed. The url in the browser displays,

localhost:3000/users?city=delhi

Instead when I create a new route, get '/users/:city' => 'users#index', :as => list_users_with_city
This works fine. I get proper output.

What could be the problem?
