Rails 应用程序在本地运行但不能在 Heroku 上运行

Question

我在 heroku 上继承了一个 rails 应用运行ning。我需要添加一些我所做的数据库字段，它在本地工作。我向 heroku 部署了一个新版本运行 db:migrate，但由于某种原因它无法正常工作。似乎认为这些字段不存在，但是运行ning db:migrate:status 我可以看到迁移有运行:

> heroku run rake db:migrate:status
Running rake db:migrate:status attached to terminal... up, run.6278

database: **censored***

Answer 1

您需要重新启动 Dyno 才能使迁移生效。从命令行：

heroku restart -a your_app_name
