使用Devise和Simple形式

Question

我在rails应用程序中使用设计，我将设计视图转换为使用简单形式。当我尝试使用不正确的密码格式注册时，不会显示密码的Flash消息。 Flash消息出现在其他领域。有谁知道如何解决这个问题。

<div class="container">
  <div class="panel small-5 small-centered columns">
    <div class="row">
      <h2>Sign Up</h2>
      <%= simple_form_for(resource, :as => resource_name, :url => registration_path(resource_name), 
      :html => {:multipart => true}) do |f| %>
        <%= f.input :email, label: "E-mail", :autofocus => true %>
    </div>
    <div class="row">
      <div class="row">
        <div class="small-6 columns">
          <%= f.label :password, label: "Password" %>
          <%= f.password_field :password %>
        </div>
        <div class="small-6 columns">
          <%= f.label :password_confirmation %>
          <div id="password-confirm">
