Edge Rails: parse error, unexpected $, expecting kEND

New to this environment and working my way through "Agile Web
Development with Rails".  I had a problem with decimal fields and am
using Edge Rails now to get around that issue - only I am now
experiencing other problems...

If you have this book, the exercise is Iteration A4: Prettier Listings

I have generated some ruby script with the command: ruby script/generate
scaffold product admin

The script produced is as follows:

class AdminController < ApplicationController
  def index
    list
    render :action => ''list''
  end

  # GETs should be safe (see
http://www.w3.org/2001/tag/doc/whenToUseGet.html)
  verify :method => :post, :only => [ :destroy, :create, :update ],
         :redirect_to => { :action => :list }

  def list
    @product_pages, @products = paginate :products, :per_page => 10
  end

  def show
    @product = Product.find(params[:id])
  end

  def new
    @product = Product.new
  end

  def create
    @product = Product.new(params[:product])
    if @product.save
      flash[:notice] = ''Product was successfully created.''
      redirect_to :action => ''list''
    else
      render :action => ''new''
    end
  end

  def edit
    @product = Product.find(params[:id])
  end

  def update
    @product = Product.find(params[:id])
    if @product.update_attributes(params[:product])
      flash[:notice] = ''Product was successfully updated.''
      redirect_to :action => ''show'', :id => @product
    else
      render :action => ''edit''
    end
  end

  def destroy
    Product.find(params[:id]).destroy
    redirect_to :action => ''list''
  end
end

When this script is called (http://localhost:3000/admin the following
error is generated:

app/models/product.rb:11: parse error, unexpected $, expecting kEND
RAILS_ROOT: script/../config/..

The error apparently means a missing "end" but i cannot see where...

Any clues?

It''s hard to know the problem without seeing product.rb.

Re: Edge Rails: parse error, unexpected $, expecting kEND

Hey Stephen,  if you''re using AWDwRv2, I would recommend using rails
1.2 RC 2 to work your way through the book because it''s covering the
features of rails 1.2.  Also, you should be aware that Edge is a
development branch.  Thus, things may or may not work.

Good luck,

-Conrad

Thanks Conrad.  I have resolved my problem by finding a typo and 
correcting it.  However I am still expecting ongoing problems with my 
current Rails release.

  I thought I downloaded v1.2 - the book suggests:

Download http://media.pragprog.com/titles/rails2/code/rails.zip intoyour
applications vendor directory and unzip it.  It should create a 
newdirectory called rails   In your applications top-level directory, 
issue the command rakerails:update

I did this, but rails -v still produces a version of 1.1.6.

Where else can I get Rails 1.2 RC 2 ?

That''s ok, rails -v will continue to say 1.1.6 until the official 1.2
release is out.

If you want to make sure you''ve got the right version of rails, do
this:

ruby script/about

If you see an "edge version" mentioned somewhere in the list of stats
(a number greater than 5000 or so) then you''re all set.

I am not sure which version is available via the pragprog website, but 
you can install the latest version on your machine using:

gem install rails --source http://gems.rubyonrails.org 
--include-dependencies

Personally, I have refrained from doing that until it''s stamped 1.2 
proper and froze RC2 to a development app:

rake rails:freeze:edge TAG=rel_1-2-0_RC2
