Question

我正在尝试向我的用户模型添加验证，但数据不会失败，而是继续传递。对于名字，我没有参赛作品。见下文：

1.9.3p286 :012 > user = User.new(name: "", email: "fail@fail.com")
  => #<User id: nil, name: "", email: "fail@fail.com", created_at: nil, updated_at: nil> 

1.9.3p286 :013 > user.save
   (0.1ms)  SAVEPOINT active_record_1
  SQL (1.5ms)  INSERT INTO "users" ("created_at", "email", "name", "updated_at") VALUES    (?, ?, ?, ?)  [["created_at", Sun, 23 Dec 2012 18:52:00 UTC +00:00], ["email",   "fail@fail.com"], ["name", ""], ["updated_at", Sun, 23 Dec 2012 18:52:00 UTC +00:00]]
   (0.1ms)  RELEASE SAVEPOINT active_record_1
 => true

以下是app/models/user.rb中的内容：

class User < ActiveRecord::Base
  attr_accessible(:name, :email)

  validates(:name, presence: true)
end

这应该是失败的。有什么建议？谢谢！

它应该可以工作，我想你在添加验证后没有重新加载控制台

当失败时，验证正在通过--Michael Hartl的RoR，6.2.2
