form_tag for search bar with Rails 3.0.5

I have a controller and view that should be providing a search bar that brings up that brings up a selected record on submission. I have tried several variations, including just specifying the assets_path, but usually end up with either an error or a submission to the index action, rather than the show action. Currently, I have the following in my index.html.haml:

= form_tag({:controller => 'assets', :action => 'show'}, :method => :GET) do   .field     =label_tag('Job Number').titleize

%br/

=number_field_tag :id   .actions     =submit_tag 'Search', :name => nil

This gives me the following error:

  No route matches {:controller=>"assets", :action=>"show"}

$ rake routes | fgrep asset )               assets GET / assets(.:format) {:action=>"index", :controller=>"assets"}                      POST / assets(.:format) {:action=>"create", :controller=>"assets"}            new_asset GET /assets/ new(.:format) {:action=>"new", :controller=>"assets"}           edit_asset GET /assets/:id/ edit(.:format) {:action=>"edit", :controller=>"assets"}                asset GET / assets/:id(.:format) {:action=>"show", :controller=>"assets"}                      PUT / assets/:id(.:format) {:action=>"update", :controller=>"assets"}                      DELETE / assets/:id(.:format) {:action=>"destroy", :controller=>"assets"}

How can I get a form_tag to take the user to /asset/123 (or whatever) as intended?

Routing happens based on the url, not on form parameters. You might try posting to a search action that would bounce them to the appropriate show action. Equally you could wire up some javascript to craft the correct url client side.
