Nested rest

If I might have a newbie question:

I’m trying to make a restful app with nested URL-s, like:

domain/worker/1
domain/worker/1/work_times
domain/worker/1/work_times/1

My problem is, that now the named paths are not working in my rhtml
files:

<% for work_time in @work_times %>

<%=link_to 'Show', work_time_path(work_time) %>

–> generates an error:

work_time_url failed to generate from
{:worker_id=>“1”, :controller=>“work_times”, :action=>“show”},
expected: {:controller=>“work_times”, :action=>“show”}, diff:
{:worker_id=>“1”}

I understand, that the :id => work_time.id should be the first thing
in the hash, and thats what should happen with
“work_time_path(work_time)”. But the :worker_id gets there. Could
someone help me out why this is happening?

Thx a lot!
