[Rails] validates* give me problems

Hi All,

I''m newbie to this tool and following some tutorials I''ve came
across
with this problem when configuring my webpage:

In Debian/testing, ruby1.8, rails1.1

I create my audio application which connects to a database (mysql) named 
audio with tables: 
articulos(id,titulo,descripcion,created_on,categoria_id) and 
categorias(id,titulo)

after creating and modifying the corresponding files (database.yml, 
.htaccess) I do:

ruby script/generate scaffold articulo
ruby script/generate scaffold categoria

I''ve modified my apache2''s config files in order to access my 
application through this server, so I write: http://audio and everything 
goes fine. I''m able to enter articulos and categorias, list, edit,
show,
and delete them without problems. But when I introduce in:

~app/models/categoria.rb

a line with: validates_uniqueness_of :categoria, :message => "ya
existe"

I get in my browser when creating a new categoria item:

  NoMethodError in Categorias#create

undefined method `categoria'' for #<Categoria:0x40a606cc>

RAILS_ROOT: /var/www/audio/public/../config/..

I suspect that should be validate_uniqueness_of :titulos, :message => 
"ya existe"

You''re telling the category to validate the uniqueness of the title
when
it''s created.
