heroku ActionView :: Template :: Error（未定义的方法`电子邮件'

我一直在尝试在heroku上部署应用程序，并且遇到了很多问题。我目前的问题是在注册时，我得到未定义的方法声称的电子邮件是不是一个定义函数的择偶对象。我已经运行heroku ActionView :: Template :: Error（未定义的方法`电子邮件'

heroku run rake db:migrate

和

heroku restart

这似乎并没有解决这个问题也。当我进入Heroku的终端并查看一个新的Mate对象，它具有email属性。以下是我的heroku日志：

什么是'Mate'？ 'email'字段是如何添加到'mates'表中的？是否有这样的迁移？该迁移是否承诺进行版本控制？你把最新的提交推向Heroku吗？ –

我猜email是空白，无论大家认为你得到的错误写这样的事情在您的视图：

<%= @user.email if @user.email? %>
