從頭開始進行身份驗證，由于某種原因，我的用戶電子郵件地址沒有保存到資料庫中。當我啟動控制臺并拉出一個隨機用戶時，他們的電子郵件始終為零，但為電子郵件的存在設定了驗證，并獲得了成功的用戶創建訊息。這是以前的作業，不知道是什么破壞了它。我知道這是非常簡單的事情，但它讓我在過去的幾個小時里得到了我，我希望第二雙眼睛能告訴我我做錯了什么。下面的 GitHub 鏈接 [https://github.com/smarandache1990/auth][1]

uj5u.com熱心網友回復：
email從attr_acessor（此處）中洗掉。
attr_accessor為那里列出的所有屬性創建 getter 和 setter。因此，基本上，您正在為email屬性覆寫這些方法。
關于驗證，使用這個：
validates :email, presence: true, uniqueness: true
