title: rake db:migrate doesn't seem to work in production
body: <p>I have two instances of my app: one for development, one for production. My development database is called <code>snip_development</code> and my production database is called <code>snip</code>.</p>
  
  <p>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 <code>rake db:migrate</code> doesn't seem to have any effect. After I run <code>rake db:migrate</code> and log into my database server, I can see that <code>snip_development</code> has all the tables I expect it to but <code>snip</code> doesn't have any tables at all.</p>
  
  <p>I suspect the problem is that <code>rake db:migrate</code> is running on <code>snip_development</code> instead of <code>snip</code> and that's why I'm not seeing anything happen.</p>
  
  <p>How do I get my migrations to work on my production database?</p>
