我正在开发我的应用程序时，控制台突然出现了一个错误。

使用 Rails 控制台时，我无法创建或保存模型。这是我得到的错误：

rvm/gems/ruby-1.9.3-p374/gems/activesupport-3.2.11/lib/active_support/callbacks.rb:418: syntax error, unexpected '=', expecting ')'
              result = result = _callback_before_71

我恢复到以前在 git 中的提交，但它仍然无法正常工作......

完整的错误信息：

今晚我遇到了同样的问题，所以我将猜测导致您问题的代码。我的假设是您未能保存的模型使用的是 has_secure_password 类方法。根据我的经验，当您尝试对临时“密码”字段执行预定义验证（validates_presence_of、validates_length_of 等）时，您会遇到上述错误。当我切换到类似于 urgetopunt 在此博客文章中使用的验证时，错误消失了。

希望这对您有所帮助。
