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/…
