ActiveRecord::ConnectionNotEstablished error with ruby on rails
<p>I was trying to learn ruby on rails, so I installed the <code>gem</code> version 4.0.0, when I start my server, and go to <code>localhost:8000</code>, it brings me an error page with error message:</p>

<blockquote>
  <p>ActiveRecord::ConnectionNotEstablished.</p>
</blockquote>

<p>I'm using sqlite3, not MySQL. Any help is appreciated.</p>

<p>edit: i fixed it, had to do with my database.yml </p>
