在使用Heroku部署我的应用程序Rails 4后，我遇到了一些问题。 该应用程序在开发中非常有效，但它在生产中并不完全有效。某些页面不显示（显示）=白页，特别是对于具有数据库的页面。我认为我有一些Sqlite3和/或postgresql的问题，但我不必解决问题。请帮帮我。

答案 2 :(得分：0)
我不知道你是否已经完成了整个过程，所以我觉得详细说明不会有什么坏处：
在Heroku上创建新应用后，您应该在资源中添加Postgres Add-on。它将创建一个名为DATABASE_URL的环境变量，您可以在settings/config variables中找到该变量。您应该在database.yml中添加此变量的名称，如下所示：
production:
<<: *default
database: DATABASE_URL
然后你会推送这个文件，运行heroku rake db:migrate，你应该好好去。
值得一提的是，您的developerWorks上没有填充Heroku上的新数据库，所以换句话说，您将从一个空数据库开始。

我不知道为什么，但我成功地解决了这个问题。
我只需将production.rb行更改为config.action_controller.perform_caching = true到config.action_controller.perform_caching = false
我不明智，但现在有效。 谢谢大家的帮助
