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)
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?
