class Author
  has_many :books

  validates :email, :presence => true
end

class Book
  belongs_to :author

  validates :title, :presence => true
end

跳过验证很简单:

a = Author.new
a.save(:validate => false)

但是,在创建书籍而不跳过书籍验证时,我需要跳过作者验证,如下所示:

b = Book.new
b.title = "A Book"

b.author = Author.last
b.save
