Validation Railstutorial.org 6.2.4格式验证

在Hartl的Railstutorial.org上工作时，我遇到了一个问题，那就是如何让测试通过电子邮件进行格式验证

My user.rb如下所示：

class User < ActiveRecord::Base       
  validates :name, presence: true, length: { maximum:50 }
  VALID_EMAIL_REGEX = /\A[\w+\-.]+@[a-z]+\z/i
  validates :email, presence: true, format: { with: VALID_EMAIL_REGEX }
end

class User < ActiveRecord::Base
  validates :name,  presence: true, length: { maximum: 50 }
  VALID_EMAIL_REGEX = /\A[\w+\-.]+@[a-z\d\-.]+\.[a-z]+\z/i
  validates :email, presence: true, format: { with: VALID_EMAIL_REGEX }
end

我的错误列表如下： 失败：

  1) User
     Failure/Error: it { should be_valid}
       expected #<User id: nil, name: "Example User", email: "user@example.com",
created_at: nil, updated_at: nil> to be valid, but got errors: Email is invalid

     # ./spec/models/user_spec.rb:13:in 'block (2 levels) in <top (required)>'

  2) User when email format is valid should be valid
     Failure/Error: expect(@user).to be_valid
       expected #<User id: nil, name: "Example User", email: "user@foo.COM". cre
ated_at: nil, updated_at: nil> to be valid, but got errors. Email is invalid
     # ./spec/models/user_spec.rb:45:in 'block (4 levels) in <top (required)>'
     # ./spec/models/user_spec.rb:43:in 'each'
     # ./spec/models/user_spec.rb:43:in 'block (3 levels) in >top (required)>'

Failed examples:

1）用户
失败/错误：它{应该是有效的}
应为有效，但出现错误：电子邮件无效
#./spec/models/user_spec.rb:13:in'block（2层）in'
2） 当电子邮件格式有效时，用户应该是有效的
失败/错误：期望（@user）.有效
应为有效，但出现错误。电子邮件无效
#./spec/models/user_spec.rb:45:in'block（4层）in'
#./spec/models/user_spec.rb:43:in'each'
#./spec/models/user_spec.rb:43:in'block（3层）in>top（必选）>'

我确信我遗漏了一些次要的东西（当我很难弄清楚的时候，通常是次要的）。如果能得到任何帮助，我将不胜感激。

本教程中的确切代码如下：

class User < ActiveRecord::Base       
  validates :name, presence: true, length: { maximum:50 }
  VALID_EMAIL_REGEX = /\A[\w+\-.]+@[a-z]+\z/i
  validates :email, presence: true, format: { with: VALID_EMAIL_REGEX }
end

class User < ActiveRecord::Base
  validates :name,  presence: true, length: { maximum: 50 }
  VALID_EMAIL_REGEX = /\A[\w+\-.]+@[a-z\d\-.]+\.[a-z]+\z/i
  validates :email, presence: true, format: { with: VALID_EMAIL_REGEX }
end

class用户

您的

有效电子邮件\u REGEX=/\A[\w+\-.]+@[A-z]+\z/i

缺少一些字母。

谢谢。我一直在用户规范中寻找答案。非常感谢！
