ruby-on-rails - rails + 设计 : Custom login failure flash messages?

Question

我试图在用户登录失败时显示闪烁警报。但是，会有两种不同的情况:

1. 用户输入的电子邮件存在，但密码错误。我希望显示此消息:The email address or password you entered is incorrect.

2. 用户输入的电子邮件不存在。我希望显示此消息:The email address and password you entered do not match our records. (You provided <span class='black'>#{params[:email]}</span>)<br/><br/>
<a href='/accounts/forgot_password' class='decorate'>Having trouble accessing your account?</a>

是否有类似于 after_sign_in_path 的钩子(Hook)我可以在哪里根据这些条件修改闪存？

更新

所以我找到了这个。但是我如何仅传递 not_found_in_database 的电子邮件变量？

en:
  devise:
    failure:
      already_authenticated: "You are already signed in."
      invalid: "The email address or password you entered is incorrect."
      not_found_in_database: "The email address and password you entered do not match our records. (You provided <span class='black'>%{email}</span>)<br/><br/><a href='/accounts/forgot_password' class='decorate'>Having trouble accessing your account?</a>."

我最终使用了这个:http://guides.rubyonrails.org/i18n.html#passing-variables-to-translations

还有这个:

                <% if !flash[:alert].blank? %>
                    <% if flash[:alert][/The email address and password you entered do not match our records/] %>
                        <div class="flashNotice col last">
                            <%= t('devise.failure.not_found_in_database', resource_name: "#{params[:user][:email]}").html_safe %>
                        </div>
                    <% else %>
                    <!-- Style for any warning message -->
                        <div class="flashNotice col last"><%= flash[:alert]%></div>
                    <% end %>
                <% end %>
