ruby-on-rails - 跳过相关对象的验证 - rails activerecord

Question

class Author
  has_many :books

  validates :email, :presence => true
end

class Book
  belongs_to :author

  validates :title, :presence => true
end

跳过验证很容易:

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

但是，在创建一本书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

Answer 1

我很不明白你的问题。在您的示例中，您没有创建任何新的作者对象:

>     b = Book.new
>     b.title = "A Book"
>     
>     b.author = Author.last
>     b.save

如果您尝试在没有电子邮件的情况下创建新作者，您不能这样做:

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

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

b.author = author
b.save

嗯......也许我只是在这里遗漏了一些明显的东西。
