title: yii2 active record find column not equal
body: <p>I have this code to find a user from db which status is active and role is user</p>
  
  <pre><code>public static function findByUsername($username)
  {
   return static::find(['username' =&gt; $username, 'status' =&gt; static::STATUS_ACTIVE, 'role'=&gt;'user']);
  }
  </code></pre>
  
  <p>I need to find a user that role is not equal to "user". How can I do this?</p>
