我正在为迈克尔·哈特尔(Michael Hartl)做的关于Rails上的 ruby 的教程，当应用程序部署时，一切在本地都可以正常运行，但是在heroku上却不能。

您需要调试此问题的任何详细信息吗？请告诉我.....

以下是heroku日志:

最佳答案

因此，我也在做《 Hart教程》，并且遇到了SAME问题。我运行了heroku运行db:migrate ....我确保它是最新的git push heroku ....它在schema.rb文件中。

我终于找到了答案:

user.rb:

将:remember_token添加到attr_accessible

例如:“attr_accessible:name，:email，:password，:password_confirmation，:remember_token”

出于某种原因，尽管现在我知道发生了什么错误，但仍将其排除在本教程之外。添加此内容后，我将其重新推送到heroku和Viola。

希望这可以帮助 :)
