为什么我得到这个Heroku和Rails错误？

Question

我想在Heroku上部署我的Rails web应用程序。 我用脚手架来生成两个表格。在我的机器上，它使用SQLite完美工作。

我上传了我的应用程序到heroku，现在有一个奇怪的问题。当我使用：

heroku config:add RACK_ENV=development 

它与SQL表一起使用。当我改回生产它表明：

We're sorry, but something went wrong. 

We've been notified about this issue and we'll take a look at it shortly. 

我在终端上键入：

heroku logs 

输出：

Answer 1

考虑到它在发展模式，但不生产，我会说最有可能的罪魁祸首是你的production.rb文件作为约翰·贝诺建议。接下来我要尝试的是在本地生产模式下运行它。如果没有别的，你应该得到更好的错误消息。

Answer 2

我知道我之前有过很多麻烦。这是Heroku根本不支持sqlite3的问题。他们删除你的database.yml文件，并使用一个新的，它使用MySQL。有几件事要检查：

• 添加mysql或mysql2 gem。
• 您的应用程序是否依赖于数据库中的数据？如果是这样，你需要找到一种方法来将新数据导入到mysql中，因为你的sqlite数据库不起作用。我结束了使用yaml_db gem来做到这一点（https://github.com/adamwiggins/yaml_db）。而不得不做一些东西与
