Hello Matt, thanks for the atention.
I'm under Ruby 1.8.6 and Rails 2.3.2. The machine is a Macbook Pro
with a Core 2 Duo 2.4GHz and 4GB of RAM. I have declared the nested
conditions in the model as seen bellow.
class Kit < ActiveRecord::Base
has_many :kit_inclusions
has_many :products, :through => :kit_inclusions
accepts_nested_attributes_for :kit_inclusions, :allow_destroy =>
true
def before_validation
self.name = self.name.to_s.strip.downcase.titleize
self.comments = self.comments.to_s.strip.capitalize
end
validates_presence_of :name, :message => 'é requerido'
def to_s
self.name
end
end
