What are the attributes of your Category model?
it should be something like:
class Category < ActiveRecord::Base
validates_uniqueness_of :name, :message => ‘already exists’
…
end
Hi Robby,
My Category model looking as this one:
class Categoria < ActiveRecord::Base
end
works fine, but allowing duplicate entries or void ones. If I modify the
model to look as this other one:
class Categoria < ActiveRecord::Base
validates_uniqueness_of :category, :message => “already exists”
end
I get all the stuff posted in my previous message:
NoMethodError in Categoria#create
undefined method `category’ for #Categoria:0x40873454
RAILS_ROOT: /var/www/audio/public/…/config/…

Bla, bla…
My database is this one:
audio, with tables: articulos, categorias
Some idea?
Cheers,

So that… its testing on that specific attribute. You don’t test on
the whole object to be unique with validates_uniqueness_of.
