由于无效的电子邮件或密码在rails中不起作用而导致Devise登录错误

Question

我有一个很棒的user模型。当user输入错误的password并通过显示无效的电子邮件或密码重定向回登录页面时，这是正常工作的。但是，当用户输入错误的email时，我不会得到相同的错误。我得到了一个不同的error

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

。在我的用户模型中，我有一个用户名字段(这是唯一的)。在我的例子中，用户可以同时使用username和email登录。这个customisation产生了什么问题吗？这是我的devise.en.yml文件。

Answer 1

例如，您需要在用户模型中定义一个名为login的虚拟属性，并告诉devise在authentication_keys中使用此字段。

我遇到了同样的问题，我通过更新到最新版本的devise (我目前运行的是4.2.0)解决了这个问题。您可能需要更新您的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)
