title: Adding a custom seed file
body: <p>I want to populate a new feature with dummy data, but don't want to use the db/seeds.rb file as it already has seeds other data irrelevant for this feature.</p>
  
  <p>To run the default <code>seeds.rb</code> file, you run the command <code>rake db:seed</code>. </p>
  
  <p><strong>If I create a file in the <code>db</code> directory called <code>seeds_feature_x.rb</code>, what would the rake command look like to run (only) that file?</strong></p>
