Rails - Jun 2010 - Incorrect path generation if some controller actions are under path prefix: expected behavior or bug?

Imagine I have a simple scaffolded model Order, controller
OrderControllers with all the default views etc.

Then I modify routes to have all actions except index and show be
available under /admin subdirectory:


  resources :orders, :only => [:index, :show]
  scope ''/admin'' do
    resources :orders, :except => [:index, :show]
  end

And after that on my index and show pages the following helper

  link_to ''Show'', @order
or
  link_to ''Show'', order

generate links that look like:
''http://localhost:3000/admin/orders/1''
which is obviously incorrect and leads to Routing Error.

I know how to work around this (I''m using link_to
''Show'', {action =>
''show'', :id => @order}) just wondering this is expected
behavior for
some reason or a bug?

Oh, I found the reason.

When routes are defined and helpers are generated in the
''define_hash_access'' method, the hash access function is named
the
same for show and update actions: hash_for_order_path. So the update
action''s path helper overwrites the show''s one.

I still wonder if it is a bug or a feature...

I can assume it may not RESTful what I did - routing show and update
to different URLs. Maybe according to REST is expected to be GET and
PUT to the same url.

But if specifying {action => ''show'', :id => @order}
produces correct
path, then it seems it is not prohibited to route show and update to
different urls.
