Conditional class properties based on morph relation

[attac-t]

Let's say we have a Person model which has many ContactNumber and each contact number can belong to a Business or a Customer which is a nullable morphTo relation. The following is the structure of the data classes.

class PersonData extends Data
{
  public function __construct (
   public int $id,
   public string $firstName,
   public string $lastName
  )
}

class ContactNumberData extends Data
{
  public function __construct (
   public int $id,
   public string $countryCode,
   public string $number,
   public BusinessData $business,
   public CustomerData $customer
  )
}

Within the ContactNumberData I'd like to have a separate key for business and customer and conditionally populate based on the owner morphTo relation.

Now from within the PersonController, we'll load persons.contactNumbers.owner and return PersonData::collection(Person::all());.

What would be the cleanest way to construct this nested structure using the ::collection method?

Use a custom creation method

[attac-t]

Are you referring to overriding the static from(...$payloads) method? Cause we would need this custom creation method to be invoked automatically when called from a parent's :: collection() method such as PersonData::collection(Person::all()).
