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

[URIs, Addressability, and the use of HTTP GET and POST](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](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.

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

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.

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](http://media.pragprog.com/titles/rails2/code/rails.zip) intoyour  
application’s vendor directory and unzip it. It should create a  
newdirectory called rails In your application’s 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 ?

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](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
