Question

我继承了在heroku上运行的rails应用程序。我需要添加一些我做过的数据库字段，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运行。它似乎认为这些字段不存在，但运行db：migrate：status我可以看到迁移已经运行：

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

database: **censored***

up     20160112093201  Add conference type to conference
up     20160112142416  New fields

最后两次迁移是我的。我还需要做点什么吗？

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

Rails应用程序在本地工作但不在Heroku上工作
