我创建了一个简单的模型来处理联系表：

 class ContactForm
   include ActiveAttr::Model

  attribute :name
  attribute :email
  attribute :message

  attr_accessible :name, :email, :message

  validates_presence_of :name, :email, :message
  validates_format_of :email, :with => /^[-a-z0-9_+\.]+\@([-a-z0-9]+\.)+[a-z0-9]    {2,4}$/i
end

它在开发环境中运行良好，但在生产服务器上给我一个错误，记录在 unicorn 日志中：

E, [2013-01-26T18:15:42.724973 #8940] ERROR -- : uninitialized constant ContactForm::ActiveAttr (NameError)

我遇到了同样的问题，我的解决方法是active_attr在我的gemfile.

gem 'active_attr', '0.7.0'

我在 GitHub 上发现了一个问题，其他人在这里遇到了同样的问题。

我在开发环境中遇到了同样的问题。我按照这个分步教程https://github.com/thomasklemm/email_form_rails。

当我尝试在控制台中创建新消息时，我得到：

m=Message.new
NameError: uninitialized constant Message::ActiveAttr

我使用 Rails 3.2.1，active_attributes gem 版本是 0.0.1。

编辑

我的错，似乎我在安装 gem 时犯了一个错误（不是好的那个）

从 gem 'active_attributes','0.0.1' 更改 gemfile

到 gem 'active_attr', '0.0.7'

现在它似乎工作......
