Ruby on rails 上载更改和数据库时heroku pg错误：（Sequel:：DatabaseError）

我在应用程序的本地开发版本中做了一些更改

然后我用git上传了所有的东西，就像平常一样

要将更改推送到我使用的数据库，请执行以下操作：

heroku db:push

我在我的终端上收到此错误：

然后再试一次 heroku db:推送 那不管用，所以我试了这个

heroku run rake db:migrate

那也不行

所以我创建了我的应用程序的一个新实例并推送它。获取相同错误

在方便的情况下，使用taps（db:push/pull使用的）可能无法准确复制数据，并且可能会在较大的传输中出错。要从生产系统导入或导出数据，强烈建议改用PGBackup

当您的源数据库是生产数据库而目标可能是开发数据库时，PGBACKUP不是吗？这篇文章的方向正好相反。我正在将数据库内容从开发（本地主机）发送到Heroku。

heroku run rake db:migrate
