我不确定这是否是数据库连接问题？

https://github.com/andey/bestofama/blob/master/config/database.yml

但它认为 heroku 无论如何都会覆盖生产配置？

可能是 acts as taggable 的问题。但为什么？该应用程序在本地运行良好。 顺便说一句:这是我第一次尝试部署 ruby​​ 2.0.0 和 rails 4 升级。

最佳答案

Rails 正在 Assets 编译阶段尝试连接到您的数据库。这可以通过以下方式禁用:

配置/应用程序.rb

config.assets.initialize_on_precompile = false

您可以让heroku在 Assets 编译期间访问环境

heroku labs:enable user-env-compile
