Suggestion po, you may get members in the `Klub` class since they are connected by klub id po. :smile:
ex.
```php
$klub = Klub::get($klub_id);
$klub->getMembers(ITEMS_PER_PAGE);
```

And then in the `Klub` class, you may write `getMembers()` like this:

```php
public function getMembers($items_per_page) {
    return Members::getByKlubId($this->id);
}
```

Although we are getting the members in the `Klub` class, the object returned is still an instance of the `Member` class. With this, you can save a few lines, eliminate the class initialization in controller, and made your code simple and more readable po :bow:
