title: Rails: 'Could not find table' error
body: <p>I developped a simple rails application that runs perfectly on my development machine.</p>
  
  <p>When I put it on the production server (Phusion Passenger/Nginx), it returns me that error in the <code>my_app/log/production.log</code> file:</p>
  
  <pre><code>ActiveRecord::StatementInvalid (Could not find table 'categories')
  </code></pre>
  
  <p>What is wrong?</p>
  
  <p>PS: After a naming error, the table name was edited manually but it works great in the development mode. I don't suspect that misnaming error.</p>
