You need to either use an old version of Rails (say, 1.2.6) for that  
tutorial or find a tutorial that is based on Rails 2.x

The dynamic scaffold as used in that old tutorial is no longer  
available.  You can use the new static scaffold generator to get  
started:

   script/generate scaffold

Read the help message that it provides, and then give it the arguments  
that you need (and perhaps you can still follow most of the old  
tutorial).

When I run that (against a Rails 2.0.2 project):

$ script/generate scaffold
Usage: script/generate scaffold ModelName [field:type, field:type]

Options:
         --skip-timestamps            Don''t add timestamps to the  
migration file for this model
         --skip-migration             Don''t generate a migration file  
for this model

Rails Info:
     -v, --version                    Show the Rails version number  
and quit.
     -h, --help                       Show this help message and quit.

General Options:
     -p, --pretend                    Run but do not make any changes.
     -f, --force                      Overwrite files that already  
exist.
     -s, --skip                       Skip files that already exist.
     -q, --quiet                      Suppress normal output.
     -t, --backtrace                  Debugging: show backtrace on  
errors.
     -c, --svn                        Modify files with subversion.  
(Note: svn must be in path)

Description:
     Scaffolds an entire resource, from model and migration to  
controller and
     views, along with a full test suite. The resource is ready to use  
as a
     starting point for your restful, resource-oriented application.

     Pass the name of the model, either CamelCased or under_scored, as  
the first
     argument, and an optional list of attribute pairs.

     Attribute pairs are column_name:sql_type arguments specifying the
     model''s attributes. Timestamps are added by default, so you
don''t
have to
     specify them by hand as ''created_at:datetime
updated_at:datetime''.

     You don''t have to think up every attribute up front, but it helps
to
     sketch out a few so you can start working with the resource  
immediately.

     For example, `scaffold post title:string body:text  
published:boolean`
     gives you a model with those three attributes, a controller that  
handles
     the create/show/update/destroy, forms to create and edit your  
posts, and
     an index that lists them all, as well as a map.resources :posts
     declaration in config/routes.rb.

Examples:
     `./script/generate scaffold post` # no attributes, view will be  
anemic
     `./script/generate scaffold post title:string body:text  
published:boolean`
     `./script/generate scaffold purchase order_id:integer  
amount:decimal`
------------------->8------->8------->8------->8------->8------- 
 >8------->8---

So you need to run the script/generate with the arguments that you  
want (and probably restart your server so the new routes can be  
parsed) and then continue with the tutorial.

Re: script/generate scaffold user

I have a database rgams_dev with table users

users:
user_email_id | varchar(100)
user_password | varchar(100)

I typed:

C:\RailsApps\rgams\script\generate scaffold User [user_email_id:varchar, 
user_password:varchar]

There''s no problem creating the corresponding files and what not, but I
still get the error:

Routing Error

No route matches "/user" with {:method=>:get}


-----------------
This is my database.yml

# MySQL 5.0.x for Win32
development:
  adapter: mysql
  encoding: utf8
  database: rgams_dev
  username: root
  password: symantec
  host: localhost
test:
 adapter: mysql
 database: rgams_test
 username: root
 password: symantec
 host: localhost
production:
 adapter: mysql
 database: rgams_prod
 username: root
 password: symantec
 host: localhost

Do I need to include ''socket:'' into that? Like,

development:
  adapter: mysql
  encoding: utf8
  database: rgams_dev
  username: root
  password: symantec
  host: localhost
  socket:

If so, I haven''t been able to find the mysql.sock file. Or if
it''s not
that one that''s suppose to go there, what is?

Thanks so much!

Re: script/generate scaffold user

You''re doin it wrong.
> C:\RailsApps\rgams\script\> generate scaffold User
[user_email_id:varchar,
> user_password:varchar]
Rails has its own way of defining tables. Most of the tutorials out there
are terriblly out of date.
You''re trying to use sql stuff when creating your tablle,
That''s causing the
generators to freak out and not build what you need.


You want to do this:

c:
cd\RailsApps\rgams
ruby script\generate scaffold user email:string password:string

This generates a migration to build the table. The primary key , though not
specified, will be created for you and it will be called "id".  In the
example you provided, your field names were prefixed with user_ which is not
necessary (or good practice) in Rails.  Finally, I assume you want to store
their email address, not email_id...    Rails, by default, thinks _id means
a key to another table (a foreign key, but there''s not Foreign Key
Constraint.

Really, you should just buy
http://pragprog.com/titles/rails3/agile-web-development-with-rails-third-editionin
PDF and learn how this all actually works. It can be very frustrating
learning Rails off the web.

Re: script/generate scaffold user

Thanks Brian, I am going to purchase the pdf... I managed to figure a 
few things out, but when I go to create a new user at

http://localhost:3000/users

this error pops up when i click create:

 ActiveRecord::StatementInvalid in UsersController#show

Mysql::Error: Unknown column ''users.id'' in ''where
clause'': SELECT * FROM
`users`     WHERE (`users`.`id` = ''0'')

This is in users_controller.rb:

  def show
    @user = User.find(params[:id])

    respond_to do |format|
      format.html # show.html.erb
      format.xml  { render :xml => @user }
    end
  end

In the mysql database, I see the added user, so it added fine.

Thanks
