I found out that including only one model in the boot method it discovers all other models and their relations. That is a strange behaviour that should be checked.
public function boot(): void
{
Sanctum::usePersonalAccessTokenModel(PersonalAccessToken::class);
// \Lodata::discover(\App\Models\Customer::class);
// \Lodata::discover(\App\Models\ProductType::class);
\Lodata::discover(\App\Models\Status::class); -->> I only want this discovered
dd(\Lodata::getResources()); -->> this prints out all models + relations
}
