How do I add model settings to a model?

Model settings provide a consistent way to store configurable settings against an Eloquent model. There are various steps needed to be followed to setup model settings for a model.
First, add the 
\Aero\Common\Traits\CanHaveSettings to the model and optionally define a 
RELATION_KEY:
class Acme extends Model
{ 
    use \Aero\Common\Traits\CanHaveSettings;
    public const RELATION_KEY = 'acme' //optional
  
    //...
}
If you added a 
RELATION_KEY make sure to add it to the relation morph map.
Then update create/update requests for this model to wrap the existing rules with 
::getSettingRules():
class CreateAcmeRequest extends AeroRequest
{
    public function rules(): array
    {
        return Acme::getSettingRules([
            //...
        ]);
    }
}
This adds the validation rules required by the model settings alongside the request's normal validation rules.
Finally, after validating the requests, save the model using 
saveSettings():
$data = $request->validated();
$acme->saveSettings($data['settings'] ?? [], true);
For UI support, you must include the model settings partial in your views:
@include('admin::settings.model-settings', ['model' => $acme ?? new Acme()])
