问题描述
我的应用有两个实例:一个用于开发，一个用于生产.我的开发数据库名为 snip_development，我的生产数据库名为 snip.
I have two instances of my app: one for development, one for production. My development database is called snip_development and my production database is called snip.
我一直在我的开发环境中进行迁移，并且一切顺利.我最近创建了我的应用程序的生产实例，但 rake db:migrate 似乎没有任何效果.在我运行 rake db:migrate 并登录到我的数据库服务器后，我可以看到 snip_development 拥有我期望的所有表，但 snip根本没有任何桌子.
I've been doing migrations all along in my development environment and it's been going just fine. I recently created a production instance of my app but rake db:migrate doesn't seem to have any effect. After I run rake db:migrate and log into my database server, I can see that snip_development has all the tables I expect it to but snip doesn't have any tables at all.
我怀疑问题在于 rake db:migrate 在 snip_development 而不是 snip 上运行，这就是为什么我没有看到任何东西发生.
I suspect the problem is that rake db:migrate is running on snip_development instead of snip and that's why I'm not seeing anything happen.
如何让我的迁移在我的生产数据库上工作?
How do I get my migrations to work on my production database?

Sometimes I forget about Google. The answer is this:
