Capistrano部署擦除数据库？ [英] Capistrano Deploy Wipes Database?

问题描述

我已经设法使用Capistrano将我的应用程式部署到生产中，但我不明白如何处理我的资料库。我使用颠覆和乘客。

I've managed to deploy my app to production using Capistrano, but I don't understand how to deal with my database. I'm using subversion and passenger.

当我运行cap部署时，新的部署开始一切新鲜。它会清除添加到数据库的数据。显然，必须有一个解决方案，但我很惊讶，没有找到任何在线的如何处理这一点。我已经阅读了Capistrano文档和许多教程。

When I run cap deploy, the new deployment starts everything fresh. It wipes out the data that was added to the database. Obviously, there must be a solution, but I'm very surprised not to find anything online about how to deal with this. I've read the Capistrano documentation and many tutorials.

我可以找到的最好的是高级Rails食谱书，其中涉及将用户生成的内容放入共享目录，但它不是准确的点。

The best I can find is the Advanced Rails recipes books, which talks about putting user-generated content into the shared directory, but it's not exactly on point.

在使用Capistrano部署时如何处理数据库？

Chances are you are using SQLite, and you are keeping the database in the default location. Your database is not being deleted, more just left behind.

You need to edit your database.yml and tell it to keep your production database in a shared location "../../shared/database.yml" or similar (you may be better off using an absolute path, or for bonus points MySQL).

当你通过capistrano它会在带时间戳的目录中创建应用程序的新副本。您的数据库会留在旧的时间戳记目录中。

When you deploy via capistrano it creates a new copy of your app in a timestamped directory. Your database is being left behind in the old timestamped dir.
