In einem Plugin war noch folgende Anweisung enthalten, um beim Deinstallieren alte Attribute aus der DB zu entfernen. Das sah in etwa so aus:

```
try {
$models = Shopware()->Models();
$models->removeAttribute(...);
} catch (Exception $exception) {
  //
}

```

Jetzt ab SW 5.5.x kann ich das Plugin nicht mehr deinstallieren weil:

```
Got error 'PHP message: PHP Fatal error:  
Uncaught Error: Call to undefined method Shopware\\Components\\Model\\ModelManager::removeAttribute() 

```

**Habe ich etwas übersehen?**

Wahrscheinlich die Shopware Entwickler upgrade guides 😉

Hey

ich zitiere mal den Upgrade Dev Guide:

> - The methods&nbsp;`ModelManager::addAttribute`&nbsp;and&nbsp;`ModelManager::removeAttribute`&nbsp;were removed. Use&nbsp;`\Shopware\Bundle\AttributeBundle\Service\CrudService::update`&nbsp;instead.

> **[Shopware 5 upgrade guide](https://developers.shopware.com/developers-guide/shopware-5-upgrade-guide-for-developers/#search-results)**
>
> Shopware 5 upgrade guide

Die Funktion war als deprecated markiert.

LG Andre&nbsp;
