Hi,
In Debian/testing (mysql-5.0.20, ruby1.8, rails 1.1.0)
Im trying to follow up the fourdaysonrails tutorial, and when putting:
validates_uniqueness_of :category, :message => "Already exists"
in /myapplication/app/model/category.rb
I get:
NoMethodError in Categories#create
undefined method `category'' for #<Article:0x407f6418>
RAILS_ROOT: /var/www/audio/public/../config/..
Application Trace | Framework Trace | Full Trace
#{RAILS_ROOT}/vendor/rails/activerecord/lib/active_record/base.rb:1786:in
`method_missing''
#{RAILS_ROOT}/vendor/rails/activerecord/lib/active_record/validations.rb:300:in
`validates_each''
#{RAILS_ROOT}/vendor/rails/activerecord/lib/active_record/validations.rb:299:in
`validates_each''
.
.
.
Don''t know what i''m doing wrong
Cheers,
Antonio

You don''t test on the whole object to be unique with validates_uniqueness_of. -Robby Robby Russell Founder & Executive Director PLANET ARGON, LLC Ruby on Rails Development, Consulting & Hosting www.planetargon.com www.robbyonrails.com +1 503 445 2457 +1 877 55 ARGON [toll free] +1 815 642 4968 [fax]

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/..
