Rails - May 2008 - Resource routing error with the route equipment/new

I''m having an issue with resource routing after running a "ruby
script/generate scaffold equipment" command. I did not make any changes
to the equipment model/controller/views after running this.

The full command I ran (all one line) ...

ruby script/generate scaffold equipment
name:string description:text contact:text keywords:string
created_at:datetime created_by:integer
updated_at:datetime updated_by:integer

IN config/routes.rb I have the following placed above the default routes
...

map.resources :equipment

--

The following routes work (I added ID#1 directly into the database) ...
/equipment
/equipment/1
/equipment/1/edit

The following route fails ...
/equipment/new

--

When going to /equipment/new ...

ActionController::RoutingError in Equipment#new
Showing equipment/new.html.erb where line #5 raised:
equipment_url failed to generate from {:controller=>"equipment",
:action=>"show"} - you may have ambiguous routes, or you may need
to
supply additional parameters for this route.  content_url has the
following required parameters: ["equipment", :id] - are they all
satisfied?

Extracted source (around line #5):
2:
3: <%= error_messages_for :equipment %>
4:
5: <% form_for(@equipment) do |f| %>
6:   <p>
7:     <b>Name</b><br />
8:     <%= f.text_field :name %>

--

I''ve tried adding the following to inflections.rb (one at a time, not
simultaneously) even though I think ''equipment'' is already in
the
standard rails inflections code, and nothing changed ...

Inflector.inflections do |inflect|
 inflect.uncountable %w( equipment )
end

Inflector.inflections do |inflect|
 inflect.irregular ''equipment'', ''equipment''
end

--

I also tried changing routes.rb to the following, which caused
equipment/new to work but the other three routes to fail ..

map.resources :equipment, :singular => :equipment_instance

--

Any ideas on what could be happening?

THANKS!
- Dave

Running "rake routes" showed something odd. Instead of
"equipment", the
plain GET route is shown as "equipment_index". Is there any way to 
override/fix this?

Nevermind, it has to be ''equipment_index'' because the plain
''equipment''
is being used by the ''show'' action.

And now my first lesson in named resource routes is complete :-)
