在表單提交底部顯示錯誤消息

Question

是否有一個twitter boot strap類在表單提交按鈕底部顯示所有驗證錯誤消息？

<div class="row-fluid"> 
<div class="span12"> 
    <div class="devise-body"> 

<%= simple_form_for(resource, :as => resource_name, :url => registration_path(resource_name), 
     :html => { :class=>'control-group error'}) do |f| %> 
     <%= f.error_notification %> 
     <div class="controls"> 
     <div class="row-fluid"> 
      <div class="span6"> 
      <%= f.input :first_name,:required=>true,:autofocus => true %> 
          </div> 
      <div class="span6"><%= f.input :last_name,:required=>true%> 
     </div> 
     </div> 
     <div class="row-fluid"> 
      <div class="span6"><%= f.input :company %></div> 
      <div class="span6"><%= f.input :title %></div> 
     </div> 

     <div class="row-fluid"> 
      <div class="span6"> <%= f.input :email, :required => true %></div> 
      <div class="span6"><%= f.input :phone_number %></div> 
     </div> 


     <%= f.input :password, :required => true %> 
     <%= f.input :password_confirmation, :required => true %> 
     </div> 
     <div class="form-actions" > 
     <!-- #class="form-actions" --> 
     <%= f.button :submit, "Sign up" ,:class => 'btn'%> 
     </div> 
    <% end %> 
    <%= render "devise/shared/links" %> 
    </div> 

</div>

如果我是你，我會用自己的警報類：
