2)created the table name contacts in the addressbook database name in Mysql.

3) altered in the database.yml

  adapter: mysql   database: addressbook   host: localhost   username: root   password: root   pool: 5   timeout: 5000

4) ruby script/generate model contact

5)ruby script/generate controller contact

6)ruby script/generate scaffold contacts.

7) altered in

class ContactController < ApplicationController   model :contact   scaffold :contact end

Errors:

model is unknown.

8) class ContactsController < ApplicationController   def list     @contacts = Contact.find_all   end   def show     @contact = Contact.find(@params['id'])   end   def create     @contact = Contact.new(@params['contact'])     if @contact.save       flash['notice'] = 'Contact was successfully created.'       redirect_to :action => 'list'     else       render_action 'new'     end   end 9) list.rhtml

<% for contact in @contacts %>   <tr>   <% for column in Contact.content_columns %>     <td><%=h contact.send(column.name) %></td>   <% end %>     <td><%= link_to 'Show', :action => 'show', :id => contact.id %></td>     <td><%= link_to 'Edit', :action => 'edit', :id => contact.id %></td>     <td><%= link_to 'Destroy', :action => 'destroy', :id => contact.id %></td>   </tr> <% end %>

Your tutorial is 3 and a half years old. Rails has changed tremendously since then. A lot of that information in that tutorial doesn't cover how newer versions of rails do it or just won't work anymore.

7) altered in

class ContactController < ApplicationController model :contact scaffold :contact end

Errors:

model is unknown.

Both the model and scaffold methods were removed

8) class ContactsController < ApplicationController def list @contacts = Contact.find_all end def show @contact = Contact.find(@params['id']) end def create @contact = Contact.new(@params['contact']) if @contact.save flash['notice'] = 'Contact was successfully created.' redirect_to :action => 'list' else render_action 'new' end end

Error: end

C:/Ruby/AddressBook/app/controllers/contacts_controller.rb:16: syntax error, unexpected $end, expecting kEND

If you indent that file properly it should be clear that you are indeed missing an 'end'

Ruby on Rails 2.2.2 is the current stable release of Rails.

Books:

That should get you started. Also from those links, look for other related links and get to know the community of Rails developers. Find and read their blogs. There is a ton of really good information out there, once you know where to start looking.
