Question

我在我的应用程序上进行的更改很容易在我的localhost：3000中看到，但是，如果我通过链接（http://amanjotkaur-bloccit.herokuapp.com/）进行了更改，则注册或登录等操作无效。收到此消息错误：我们很抱歉，但出了点问题。如果您是应用程序所有者，请检查日志以获取更多信息。

我已经在流浪汉上运行了heroku日志，这就是我得到的：

我没有看到任何错误！

Answer 1

您的gem文件是否具有适用于Heroku的开发和生产数据库？当我忘记添加postgres时，我收到了类似的错误。

 group :production do
      gem 'pg'
      gem 'rails_12factor'
    end

    group :development do
      gem 'sqlite3'
    end

Answer 2

这似乎是一个Devise错误（基于导致它的原因 - 注册和登录，但不是关于 - 以及错误日志中的“Warden”）。

可能没有正确配置Devise。

看看this article。

在config/initializers/devise.rb文件中，您需要将某些内容设置为密钥。如果你还没有使用rake secret（在CL中）生成一个。然后将其保存为环境变量，并确保它在Heroku和您当地的环境中。

如果您已经拥有一个安全的环境变量密钥，则可能是另一个Devise配置问题。

我的生产应用程序上的操作无法通过Heroku运行
