Has anybody noticed validates_uniqueness_of missing in rails 3.0 rc2? I'm not
sure if this is a bug or I'm just doing something wrong.
Here's what I'm doing.
Class 1:
class Title < ActiveRecord::Base
validates_length_of :language, :is => 3
validates_uniqueness_of :language, :scope => :book_id
validate :language, :is_proper_language_code
validates_presence_of :value
belongs_to :book
def is_proper_language_code
errors.add(:base, "invalid language code") unless !ISO_639::ISO_639_2.find{
|lang| lang[0] == self.language }.nil?
end
end
Class 2:
class Book < ActiveRecord::Base
attr_accessible :titles
validates_presence_of :titles
has_many :titles
end
Spec:
before(:each) do
@valid_title_attributes = {:book_id => 1, :language => "eng", :value =>
"..."}
@book = Book.new
@book.titles.push(Title.new(@valid_title_attributes))
end
it "should not have multiple titles with same language attribute" do
@book.titles.clear
@book.titles.push(Title.new(@valid_title_attributes))
@book.titles.push(Title.new(@valid_title_attributes))
@book.should_not be_valid
@book.titles.clear
@book.titles.push(Title.new(@valid_title_attributes))
@book.should be_valid
end
