Question

我有一个旧的rails应用程序曾经使用过Devise 2，但由于它从未显示任何闪存或错误消息，我决定将其升级到最新的希望它会有所帮助。它没有。我搜索了很多，但都没有成功。

现在，我得到了rails 3.2.21并设计了3.4.1。我没有自定义控制器，所有生成的视图只是略有改变。当我登录并填写正确的凭证时，我登录。当我输入错误的凭据时，会记录下来：

没有显示闪烁或错误消息。 application.html.erb：

<% flash.each do |type, message| -%>
  <div class="message <%= type %>">
    <%= message %>
  </div>
<% end -%>

和sessions/new.html.erb：

<h2>Einloggen</h2>
<%= form_for(resource, :as => resource_name, :url => session_path(resource_name)) do |f| %>
  <%= devise_error_messages! %>
  <div><%= f.label :email, 'E-Mail' %><br />
  <%= f.email_field :email, :autofocus => true %></div>
  <div><%= f.label :password, 'Passwort' %><br />
  <%= f.password_field :password %></div>
  <% if devise_mapping.rememberable? -%>
    <div><%= f.check_box :remember_me %> <%= f.label :remember_me, 'Login merken?' %></div>
  <% end -%>
  <div><%= f.submit "Einloggen" %></div>
<% end %>
<%= render "devise/shared/links" %>

任何人都可以告诉我这有什么问题以及为什么它没有显示闪存/错误消息？

Answer 1

这是我过去用来呈现消息的一个例子

<% flash.each do |key, value| %>
  <div class="alert alert-dismissible alert-<%= key.to_s == 'notice' ? 'success' : 'danger' %>" role="alert">
   <button type="button" class="close" data-dismiss="alert">
     <span aria-hidden="true">&times;</span><span class="sr-only">Close</span></button>
       <%= value if value.is_a?(String) %>
  </div>
<% end %>
