Rails - May 2006 - Newbie Help

Is it my environment? Is something wrong, cause I thought this should 
just work?

I have a simple table and I created a model and a controller:

ruby script/generate controller Restaurant
ruby script/generate model Restaurant

I edited the controller to this:

class RestaurantController < ApplicationController
  scaffold :Restaurant
end

I run it and:

http://0.0.0.0:3000/Restaurant works fine, gives me a list of 
restaurants.

If I click on edit though I get this:

Showing 
usr/local/lib/ruby/gems/1.8/gems/actionpack-1.12.1/lib/action_controller/templates/scaffolds/edit.rhtml
where line #4 raised:

wrong number of arguments (0 for 1)
Extracted source (around line #4):

1: <h1>Editing <%= @scaffold_singular_name %></h1>
2:
3: <%= error_messages_for(@scaffold_singular_name) %>
4: <%= form(@scaffold_singular_name, :action => 
"update#{@scaffold_suffix}") %>
5:
6: <%= link_to "Show", :action =>
"show#{@scaffold_suffix}", :id =>
instance_variable_get("@#{@scaffold_singular_name}") %> |
7: <%= link_to "Back", :action =>
"list#{@scaffold_suffix}" %>

Likewise if I click on New:

ArgumentError in Restaurant#new

Showing 
usr/local/lib/ruby/gems/1.8/gems/actionpack-1.12.1/lib/action_controller/templates/scaffolds/new.rhtml
where line #4 raised:

wrong number of arguments (0 for 1)
Extracted source (around line #4):

1: <h1>New <%= @scaffold_singular_name %></h1>

4: <%= form(@scaffold_singular_name, :action => 
"create#{@scaffold_suffix}") %>
5:
6: <%= link_to "Back", :action =>
"list#{@scaffold_suffix}" %>


Here''s my table definition;

CREATE TABLE `restaurants` (
  `id` INTEGER NOT NULL AUTO_INCREMENT,
  `name` VARCHAR(100) NOT NULL DEFAULT '''',
  `phone` VARCHAR(14) NOT NULL DEFAULT '''',
  `fax` VARCHAR(14) NOT NULL DEFAULT '''',
  `email` VARCHAR(100) DEFAULT '''',
  `web` VARCHAR(100) DEFAULT '''',
  `address1` VARCHAR(100) NOT NULL DEFAULT '''',
  `address2` VARCHAR(100) DEFAULT '''',
  `city` VARCHAR(100) NOT NULL DEFAULT '''',
  `state` CHAR(2) NOT NULL DEFAULT '''',
  `zip` VARCHAR(10) NOT NULL DEFAULT '''',
  `open` BOOLEAN NOT NULL DEFAULT 0,
  PRIMARY KEY(`id`)
)
ENGINE = InnoDB
CHARACTER SET utf8;
