I am using nested resources as follows:
map.resources :topics do |topics|
topics.resources :items do |items|
items.resources :attachments
end
end
When I generate a RESTful path for new item in the console:
app.new_topic_item_path(2) then I get correct path as
'/topics/2/items/new'.
However, for the new attachment I am getting error:
app.new_topic_item_attachment_path(22) gives -
ActionController::RoutingError: new_topic_item_attachment_url failed to
generate from {:action=>"new", :controller=>"attachments",
:topic_id=>22}, expected: {:controller=>"attachments", :action=>"new"},

Why is it failing and how to fix this?
And, why is it generating '{:action=>"new", :controller=>"attachments",
:topic_id=>22}' ? Shouldn't it pass item_id rather than topic_id?
Any clues?

Thanks,
CS.
