Naming Error: "uninitialized constant ActionRecord"

I'm using Rails 2.0.2 with Ruby 1.8.6 on Mac OSX Leopard. I'm trying to
follow the instructions in "Ruby for Rails" by David A. Black but I'm
getting an error when I attempt to display one of the views. I know the
book was written for Rails 1.X and I'm assuming that's where the problem

For my methods I have:

class Composer < ActiveRecord::Base
  has_many :works

class Work < ActionRecord::Base
  belongs_to :composer
  has_many :editions

For my composer controller I have:
class ComposerController < ApplicationController
  def show
    @composer = Composer.find(params[:id])

Then in the view I'm having problems with this line:
  <% do |w| %>

Here's the actual error:
NameError in Composer#show

Showing composer/show.html.erb where line #5 raised:

uninitialized constant ActionRecord

Extracted source (around line #5):

2: "Works by #{@composer.first_name} #{@composer.last_name}" %>
3: <p>Click on any work to see all available editions of that work.</p>
4: <ul>
5: <% do |w| %>
6: <li><%= link_to w.title,
7: :controller => "work",
8: :action => "show",

I think it's having a problem with me calling "works" on
Composer.find(params[:id]) but since work belongs_to composer and
composer has_many works, I don't know what the naming error is. Do I
have to specify a foreign_key in the method to "works"? If so, what
would the default be if not "works".

My fault. It says ActionRecord in the book; it should be ActiveRecord.
Not my finest hour, apparently. But hang in there -- there's some
really good stuff in that book :slight_smile:

Doh, I should have realized that when there was no reference to
"ActionRecord" on google.

Thanks for the quick reply. I love the book by the way. I'm new to
programming and I was trying to struggle through "Building Your Own Ruby
On Rails Web Applications." A friend of mine recommended "Ruby for
Rails" as a better introduction book. It's exactly what I needed,
everything just clicks. =)
