Using ruby 1.8.6

1. created the rails project name

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

1. altered in the database.yml

username: root  
password: root  
pool: 5  
timeout: 5000

1. ruby script/generate model contact

5)ruby script/generate controller contact

6)ruby script/generate scaffold contacts.

1. altered in

model :contact  
scaffold :contact  
end

Errors:

model is unknown.

1. 

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 %\>

 \<% for column in Contact.content\_columns %\> \<%=h contact.send(column.name) %\> \<% end %\> \<%= link\_to 'Show', :action =\> 'show', :id =\> contact.id %\> \<%= link\_to 'Edit', :action =\> 'edit', :id =\> contact.id %\> \<%= link\_to 'Destroy', :action =\> 'destroy', :id =\> contact.id %\> \<% 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.

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

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.
