devise.en.yml无法正常工作

Question

对于那些熟悉Devise及其功能的人，您应该具备config / locales目录中Devise.en.yml文件的一些工作知识。此文件在登录时实际上会创建错误消息，即：如果您输入的密码错误，您应该看到错误消息，例如＆＃34;无效：＆＃39;无效的电子邮件或密码。＆＃34;。

在我的情况下，它不起作用，如果我输入错误的用户名/密码没有任何反应，它只是没有登录你，但没有闪存消息。

我的devise.en.yml文件内容都是绿色的，我不确定它是否应该看起来如何，但我有预感，代码可能不对吗？但这可能是也可能不是真正的原因。

不确定要包含哪些控制器或内容，一旦您提出要求，我将立即更新OP。

这是我的应用程序的devise.en.yml文件：

  en:
  errors:
  messages:
  not_found: "not found"
  already_confirmed: "was already confirmed"
  not_locked: "was not locked"

  devise:
    failure:
      unauthenticated: 'You need to sign in or sign up before continuing.'
      unconfirmed: 'You have to confirm your account before continuing.'
      locked: 'Your account is locked.'
      invalid: 'Invalid email or password.'
      invalid_token: 'Invalid authentication token.'
      timeout: 'Your session expired, please sign in again to continue.'
      inactive: 'Your account was not activated yet.'
    sessions:
      signed_in: 'Signed in successfully.'
      signed_out: 'Signed out successfully.'
    passwords:
      send_instructions: 'You will receive an email with instructions about how to reset your password in a few minutes.'
      updated: 'Your password was changed successfully. You are now signed in.'
    confirmations:
      send_instructions: 'You will receive an email with instructions about how to confirm your account in a few minutes.'
      confirmed: 'Your account was successfully confirmed. You are now signed in.'
    registrations:
      signed_up: 'You have signed up successfully.'
      updated: 'You updated your account successfully.'
      destroyed: 'Bye! Your account was successfully cancelled. We hope to see you again soon.'
    unlocks:
      send_instructions: 'You will receive an email with instructions about how to unlock your account in a few minutes.'
      unlocked: 'Your account was successfully unlocked. You are now signed in.'
    mailer:
      confirmation_instructions: 'Confirmation instructions'
      reset_password_instructions: 'Reset password instructions'
      unlock_instructions: 'Unlock Instructions'

Answer 1

我猜你必须将此代码添加到app/views/layouts/application.html.erb：

  <% if notice %>
    <p class="notice"><%= notice %></p>
  <% end %>

  <% if alert %>
    <p class="alert"><%= alert %></p>
  <% end %>

Answer 2

不确定这是不是真正的问题，而是作为一个想法。

Yaml使用标识作为范围。当你在这里复制粘贴时不确定它是否被破坏了，但如果没有，你的问题可能是你的devise.en.yml文件应该是这样的：

en:
  errors: 
    messages:
      not_found: "not found"
      ...
  devise:
    failure:
       ...

而不是你现在的问题。另外，请检查您是否使用空格，而不是标识符。
