【问题描述】:
我继承了一个在 heroku 上运行的 rails 应用程序。我需要添加一些我所做的数据库字段并且它在本地工作。我向 heroku 部署了一个新版本,运行了 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***
Status Migration ID Migration Name

up 20160112093201 Add conference type to conference
