PLease return this as an object. Returning this as an object would make it easier for you to access methods and attributes of this class whenever you need it since diet cake initializes class attributes in it's constructor by passing an associative array. Also, for readability, when fetching data via $db->row / $db->rows, it is better to use $row / $rows as the variable name.
```php
$row = $db->row('SELECT * FROM klub WHERE klub_id = ?', array($klub_id));
return new self($row);
```
