Ruby on Rails - 正則表達式電子郵件驗證不起作用

Question

我想在第6章Michael Hartl的rails教程中做正則表達式電子郵件驗證示例，但由於某些原因測試「電子郵件驗證應接受有效地址」失敗有效的電子郵件地址。按照建議，我嘗試使用Rubular的正則表達式，並通過那裏。如果有人知道它爲什麼在我的rails代碼中失敗了，我會很感激幫助解決它。謝謝。

測試失敗

test "email validation should accept valid addresses" do 
    valid_addresses = %w[user@example.com USER@foo.COM first.last@foo.jp] 
    valid_addresses.each do |valid_address| 
     @user.email = valid_addresses 
     assert @user.valid?, "#{valid_address.inspect} should be valid" 
    end 
end 

用戶類正則表達式和驗證定義

class User < ActiveRecord::Base 

    has_many :posts, dependent: :destroy 
    has_many :text_posts, dependent: :destroy 
    has_many :image_posts, dependent: :destroy 

    validates :name, presence: true, length: {maximum: 50} 

    VALID_EMAIL_REGEX = /\A[\w+\-.]+@[a-z\d\-.]+\.[a-z]+\z/i 

    validates :email, presence: true, length: {maximum: 255}, format: {with: VALID_EMAIL_REGEX} 

end

目前，你設置的用戶通過電子郵件發送給所有有效電子郵件的陣列，而不僅僅是當前的電子郵件：

@user.email = valid_addresses 

應該

@user.email = valid_address
