When you generate a link you either pass a hash of routing options
(eg :controller => 'foo', :action => '...') or you call one of the
named route helpers (person_path(...)) which can also take similar
options. You can add any options you want (although the rails way
these days would probably to make the table in question explicit in
the url path itself rather than as a query parameter)
