title: How to create schema in sql
body: <p>As per <a href="http://edgeguides.rubyonrails.org/configuring.html" rel="noreferrer">http://edgeguides.rubyonrails.org/configuring.html</a> and <a href="https://stackoverflow.com/questions/7012812/schema-rb-index-different-from-individual-migration-index">this post</a> I have this in application.rb</p>
  
  <pre><code>config.active_record.schema_format = :sql
  </code></pre>
  
  <p>However, it's still creating db/schema.rb (even after I delete it) and more importantly it's not creating the schema in sql when I run "rake db:migrate".  Anyone know what I'm doing wrong?  I'm on Rails 3.1 pre.</p>
