的Heroku运行迁移，但仍不能识别列

这是我的看法，这里的问题正在发生的事情：的Heroku运行迁移，但仍不能识别列

<div class="row" style="margin-top:10%;"> 
    <div class="four columns"></div> 
    <div class="four columns">  
     <div class="panel"> 
      <h2>Criar conta</h2> 
      <%= simple_form_for resource, :as => resource_name, :url => registration_path(resource_name), defaults: { error_html: { class: 'alert label' } } do |f| %> 
       <div><%= f.input :name, :autofocus => true, :placeholder => "Nome", label: false %></div> 
       <div><%= f.input :email, :placeholder => "E-mail", label: false %></div> 
       <div><%= f.input :password, :placeholder => "Senha", label: false %></div> 
       <div><%= f.input :password_confirmation, :placeholder => "Confirme sua senha", label: false %></div> 
       <div align="center"> 
        <%= f.submit "Cadastrar", :class => "button success" %> 
       </div> 
      <% end %> 
      <p><%= link_to "Já tenho conta", new_session_path(resource_name) %></p> 
     </div> 
    </div> 
    <div class="four columns" style="margin-top:10%;"></div> 
</div>

这是错误消息：

这是部分从Heroku的（PG：PSQL）表，以确保该列创建：

name     | character varying(255)  | 
status     | boolean      | 
confirmed_at   | timestamp without time zone | 
confirmation_token  | character varying(255)  | 
confirmation_sent_at | timestamp without time zone |

我跑rake db:version

你运行了'heroku run rake db：migrate'还迁移了heroku上的db吗？ – weltschmerz 2013-02-13 19:50:55

是的，我也重置数据库并重新创建它，但没有结果 – Gerep 2013-02-13 19:53:33

您是否重新启动了服务器？ – MrYoshiji 2013-02-13 20:36:15

你做了之后heroku run rake db:migrate你需要做一个heroku restart这样的Rails recaches ActiveRecord的结构。
