無效的電子郵件或密碼的設計登錄錯誤在Rails中不起作用

Question

我有一個設計user模型。 當user輸入錯誤的password時，通過顯示無效的電子郵件或密碼將其重定向回登錄頁面，這可以正常工作。 但是，當用戶輸入錯誤的email時，我不會收到相同的錯誤。 我遇到了另一個error

I18n::MissingInterpolationArgument at /users/sign_in
missing interpolation argument :authentication_keys in "Invalid %{authentication_keys} or password." ({:resource_name=>:user} given)

。 在我的用戶模型中，我有一個用戶名字段（這是唯一的）。 就我而言，用戶可以使用username和email登錄。 這種customisation產生任何問題嗎？ 這是我的devise.en.yml文件。

您需要在用戶模型中定義一個名為login的虛擬屬性，並告訴devise在authentication_keys使用此字段。

我遇到了同樣的問題，並通過更新到最新版本的devise解決了該問題（我目前正在運行4.2.0）。 您可能需要更新ruby版本才能使用最新版本的devise。（ https://github.com/plataformatec/devise/blob/master/CHANGELOG.md#400rc1---2016-02-01 ）
