Rails 3和Heroku：自动“rake db：migrate”推？ [英] Rails 3 and Heroku: automatically "rake db:migrate" on push?

问题描述

我对我的heroku推送/部署过程有一些轻微的烦恼，否则这个过程很快就会被发现和使用。

如果我将新迁移添加到我的应用程序中，我可以将它放到heroku服务器上的唯一方法是推送到heroku远程。这会上传并重新启动应用程序。但它不运行迁移，所以我必须做 heroku rake db：migrate --app myapp ，然后 heroku restart --app myapp 。与此同时，该应用程序已被破坏，因为它没有运行迁移，并且代码在迁移时引用了字段/表等。

必须有一种方法更改部署过程以自动运行 rake db：migrate 作为部署过程的一部分，但我无法解决这个问题。

这是我在一个heroku cpanel中设置的东西吗？这是我从命令行传递给heroku的选项吗？它是一个混帐钩子？任何人都可以设置我吗？谢谢，max

解决方案

这是一个将所有内容都包装为单行（并支持回滚）的rake任务： / p>

您仍然可以结束在老板的演示之上进行部署，但至少您不会浪费时间在 git push 和 rake db：migrate 。

I have a slight annoyance with my heroku push/deploy process, which otherwise has been a joy to discover and use.

If i add a new migration to my app, the only way i can get it up onto the heroku server is to do a push to the heroku remote. This uploads it and restarts the app. But it doesn't run the migration, so i have to do heroku rake db:migrate --app myapp, then heroku restart --app myapp. In the meantime, the app is broken because it hasn't run the migrations and the code is referring to fields/tables etc in the migration.

There must be a way to change the deployment process to run the rake db:migrate automatically as part of the deploy process but i can't work it out.

Is it something i set in a heroku cpanel? Is it an option i pass to heroku from the command line? Is it a git hook? Can anyone set me straight? thanks, max

解决方案

Here is a rake task that wraps up everything into a one-liner (and also supports rollback):

You still might wind up deploying on top of your boss's demo, but at least you don't waste time typing between the git push and the rake db:migrate.
