Неожиданная синтаксическая ошибка tANDOP on rails 3 Учебное пособие

Я думаю, что упускаю из виду что-то глупое, но я следую руководству по rails 3, и я нахожусь в той части, где я добавляю ошибки, если пользователь помещает комментарий к неопубликованной статье ... Итак, в консоли rails я попробуйте создать комментарий к «неопубликованной» статье (черновику), введя следующий код

>> article = Article.draft.first
=> #<Article id: 7, title: "One-to-many associations",        ...> 
>> comment = article.comments.create :name => 'Dude', :email => '[email protected]', :body    => 'Great article!'

Здесь говорится, что я должен получить следующее:

=> #<Comment id: nil, article_id: 7, name: "Dude", email: "[email protected]", body: "Great article!", created_at: nil, updated_at: nil> >> comment.errors.full_messages => ["Article is not published yet"]

Но вместо этого я получаю следующую ошибку:

SyntaxError: /Users/bbarton250/Sites/rails_projects/theoldman/app/models/comment.rb:11: синтаксическая ошибка, неожиданный tANDOP, ожидается kEND &&!

Вот моя модель комментариев:

class Comment < ActiveRecord::Base
  attr_accessible :body, :email, :name, :article_id

  belongs_to :article

  validates :name, :email, :body, :presence => true
  validates :article_should_be_published

  def article_should_be_published
    errors.add(:article_id, "is not published yet") if article 
&& !article.published?
  end
end

Вот моя модель статьи:

class Article < ActiveRecord::Base
  attr_accessible :body, :published_at, :title

  validates :title, :presence => true
  validates :body, :presence => true

  belongs_to :user
  has_and_belongs_to_many :categories
  has_many :comments

  scope :published, where("articles.published_at IS NOT NULL")
  scope :draft, where("articles.published_at IS NULL")
  # recent post from < a month ago - see pg 103 of tutorial
  # scope :recent, lambda { published.where("articles.published_at > ?", 1.month.ago.to_date)}
  scope :where_title, lambda { |term| where("articles.title LIKE ?", "%#{term}%") }

  def long_title
    "#{title} - #{published_at}"
  end

  def published?
    published_at.present?
  end
end

Пожалуйста, дайте мне знать, если мне нужно предоставить что-нибудь еще ... Я ценю любую помощь ... Большое спасибо

ОБНОВИТЬ:

Похоже, есть разрыв строки там, где его не должно быть:

  def article_should_be_published
    errors.add(:article_id, "is not published yet") if article && !article.published?
  end
