Heroku上的未定义方法错误，但不是本地的

Question

此错误主要针对用户帐户。我正在使用Devise gem。该应用程序在本地运行良好，我推送到Heroku，我的用户注册页面失败。这是我在Heroku日志中发现的：

ActionView::Template::Error (undefined method `name' for #<User:0x0000000455e958>):

app/views/devise/registrations/new.html.erb:12:in `block in _app_views_devise_registrations_new_html_erb___4334866443448261327_23317620'

应用程序/视图/设计/注册/ new.html.erb

<div class="panel panel-default">
  <div class="panel-heading">
    <h1>Sign up</h1>
  </div>

  <div class="panel-body">
    <%= form_for(resource, :as => resource_name, :url => registration_path(resource_name)) do |f| %>
      <%= devise_error_messages! %>

      <div class="form-group">
        <%= f.label :name %>
        <%= f.text_field :name, autofocus: true, class: "form-control" %>
      </div>

      <div class="form-group">
        <%= f.label :email %>
        <%= f.email_field :email, autofocus: true, class: "form-control" %>
      </div>

      <div class="form-group">
        <%= f.label :password %>
        <%= f.password_field :password, class: "form-control" %>
      </div>

      <div class="form-group">
        <%= f.submit "Sign up", class: "btn btn-primary" %>
      </div>
    <% end %>
  </div>

    add_column :users, :name, :string

end

Answer 1

Heroku没有相同的架构数据，因为我没有提交并推送db / development.sqlite3
