routing method problem

I have two named routes: map.edit_setting 'setting/:key', :controller => 'settings', :action => 'edit', :method => :get map.update_setting 'setting/:key', :controller => 'settings', :action => 'update', :method => :put

And I have to link_to_remote links: link_to_remote "Edit", :url => edit_setting_path(@setting.key), :method => :get link_to_remote "Save", :url => update_setting_path(@setting.key), :method => :put

But both link will trigger the :edit action. It seems Rails ignores the :method parameter when routing.

How can I map the same url with different method to different actions? Thanks!
