I was originally using instant rails, and decided to try installing ruby, rails, and mysql on my own. No problem with the install. I used gem install rails --include-dependencies, and got no errors. The problem seems to be with defining the scaffold method. I had no problems with this in Instant Rails, and i'm guessing this has something to do with Rails 2.0. Would the RoR gurus please lend a hand, and guide me to the light?

NoMethodError in AdminController#index undefined method `scaffold' for AdminController:Class
If I'm not mistaken, the issue you're having is due to the fact that
scaffolding has been deprecated as of Rails 2.0. If that's the case,
it might be a bit hard for a Rails newbie to follow along with AWDwR.
I'm pretty n00b-ish myself, so am I totally wrong about this? If I'm
not, does anyone out there have any suggestions for alternative
tutorials that don't presuppose scaffolding?

Yep, dynamic scaffolding has been moved out to a plugin in Rails 2.0.
Your options are:
1) Switch to rails 1.2.6. This will be the easiest route if you're still learning rails using AWDWR 2nd ed. 2) Install the scaffolding plugin with: script/plugin install scaffolding
Option 1 means you are continuing to tread on the same turf expected by the book, Option 2 is but on step towards adapting your knowledge, and the books, to Rails 2.0.

I'm not sure deprecated is the right term, it (dynamic scaffolding as opposed to generated scaffolds) has been moved out of the core and into a plugin in Rails 2.0. Another thing which has been moved out of core are db adapters for commercial databases like Oracle, and SQL server, these are now separate gems.
For the most part Rails 2.0 is pretty compatible with 1.2.x, however, it's probably different enough to trip up n00bs working through things like AWDWR 2nd ed. I don't know that there's a really good in-depth beginners tutorial on Rails 2.0 yet. I'd probably advise folks starting out with Rails right now to install rails 1.2.x and use that while following AWDWR.
If someone wants to persist in using AWDWR with Rails 2.0, one hint is to check the plugin repository at http://svn.rubyonrails.org/rails/plugins/ if you run into a missing function like this.
The new book "The Rails Way" looks like a very good resource on Rails 2.0 for those with some rails experience under their belt, but it's really not structured as a beginner's book.
I got the AWDWR 2nd ed for Xmas. I just ran into the "undefined method
`scaffold' for AdminController:Class" error working on my "depoot"
example. I am running on OS X and installed Rails 2.0.2. Someone
suggested I use Rails 1.2. How do I back out 2.0 and go back to 1.2? I
installed it as a "package" on OS X. It installed in /usr/local/bin.
Do I just delete it? Can rails stand alone, or do I need all the
other stuff? Maybe the scaffold plug in is easier. Can someone explain
in detail how to add that plug in?
I'm a java developer w/Unix experience, so I'm not totally clueless,
but I am very new to Rails and Ruby.

The easiest way by far is to just download Locomotive. It's self- contained, and is removed simply by dragging its folder to the trash. You'll be up and running in about two minutes after your download completes.
For even extra easiness, download MAMP as well, and have a self- contained MySQL install as well.
Jason, I've found the same trouble installing ruby on rails on Windows. I've tried to install the ruby plugin but failed. You need to do a few little changes from the original rubyonrails.org website. Here is the installation I did:
1) install ruby from www.rubyonrails.org/down. 2) Because ruby changes your path settings, open a NEW command prompt and install gems like is told on the www.rubyonrails.org/down website. In the new command prompt type "ruby setup.rb". 3) Install the correct rails with the scaffolding. If you already installed the latest rails 2.x then uninstall it with "gem uninstall rails". Then do the rails install with version 1.2.6. Type "gem install rails --version 1.2.6 --include-dependencies" 4) Looking at all the different directories, rails creates, I need the projec manager. After trying out several I found "Intype" which is very small and just do the needful in a nice view. Its still in beta and therefore its still free. Download from: "http://intype.info/home/index.php". You can download both the editor and the project manager (I've used rarzilla for the rar file). 5) Download and install the freeware package of MySQL. I'm using the essentials package. You need to register though. 6) Create your work direcory (I'm using c:\webserver\test). If you want to follow the "Hello" example from the Agile book then type: "rails Hello" cd into the "Hello" directory. Open the webserver with "ruby script/server". Open the webpage with "http://localhost:3000" and check the "about your application's environment" for the installed versions etcetera.
I too had the AWDwR book 2nd Edition, P3.0 printing (use the P2.0
errata says Dave).
I installed the scaffolding plugin. That step alone, didn't help,
although it may have been best to delete the depot folder and start
again. But that plugin may have been a different type of scaffolding.
I went back to rails version 1.2.5, that was installed when I first
set up Ruby on Linix Fedora 7. I used the commands from a later post
(Jan 1, by Jos Achten, step 3). In fact I had 1.2.5, and 2.0.2
installed and it asked me which I wanted to uninstall. In the end I
uninstalled both and asked for "--version 1.2.5 --include-
dependencies" and that did it. Then I had to delete the depot folder
and restart from the beginning of that chapter. Everything worked as
on pages 68 onward. Frankly, I'm impressed that it generated so much
automatically.

Thank you for asking the questions, and thank you for all the replies!
I just ran into the same issue and had it resolved in no time flat
thanks to you!
Summary:
1. I had installed Rails according to the Windows recommendation in
the book
2. When I ran into the problem, I googled the error message, found
this error message, and did the following:
3. typed "gem uninstall rails" at the rails command line
4. typed "gem install rails --version 1.2.6 --include-dependencies"
at the rails command line
5. delete or rename the original depot folder
6. do the following to quickly get back to where you were when the
error hit you:
D:\Rails\rails_apps\work>rails depot
cd depot
D:\Rails\rails_apps\work\depot>ruby script/generate model product
edit D:\Rails\rails_apps\work\depot\db\migrate\001_create_products.rb
add
t.column :title, :string
t.column :text, :text
t.column :image_url, :string
rake db:migrate
ruby script/generate controller admin
edit D:\Rails\rails_apps\work\depot\app\controllers
\admin_controller.rb
add
scaffold :product
(change D:\Rails to where you installed rails, obviously)
Thanks,
Werner

Just a quick correction to the last entry. When editing the migration
for the products model, the line 't.column :text, :text' should be
't.column :description, :text'. My validation kept failing until I
realized that the 'description' column had been incorrectly named as
'text'.

If you're following the AWDWR book using Rails 2 you will hit other problems - for example when it talks about pagination that has been removed from Rails 2 so it won't work as expected. While running through the Depot for learning I'd stick with 1.2.6 and then start develping on 1.2.6 so you can rely on the book. Only make the change to 2.0 when you're comfortable with the basics.

I originally got the <b>undefined method `scaffold' for
AdminController:Class</b>
then after installing pagination I got <b>undefined method `paginate'
for #<AdminController:...</b>
How I got around was this:
1) check all installed gems on your machine
<b>gem list --local </b>
check the rails versions installed (in my case, this was 2.0.2, 1.2.6,
1.2.5, 1.2.3)
2) uninstall version 2.0.2, using this command:
<b>sudo gem uninstall -v=2.0.2 rails</b>
I admit, I'm a Rails noob and have been following the instructions in
AWDwR edition *3*, they haven't mentioned lack of support for this, so
you kind of get stuck on page 76. Is it worth rolling back my version
of rails do you think, or is scaffolding something I can live/learn
without ...

Is there any place where it is summarized the changes to make to
Awdwr's depot exercise if we decide to use RoR 2.0?
It doesn't make sens to me to learn an old technology when I'm not
gonna stick with it anyways...
