Auto-filling DTOs

[sanderdlm]

DTOs are useful, but in large projects you end up having to write a lot of boilerplate code to simply pass data from Entity -> DTO and back from DTO -> entity. This PR introduces a new BaseDataTransferObject, which has a "magic" constructor that populates all public properties of a DTO with the matching value it can find if an object is passed to the constructor.

Address DTO

<?php

namespace App\DataTransferObject\Common;

use App\DataTransferObject\BaseDataTransferObject;
use App\Enum\Province;
use Symfony\Component\Validator\Constraints as Assert;

class AddressDataTransferObject extends BaseDataTransferObject
{
    #[Assert\NotBlank]
    public ?string $street = null;

    #[Assert\NotBlank]
    public ?string $number = null;

    #[Assert\NotBlank]
    public ?string $zipCode = null;

    #[Assert\NotBlank]
    public ?string $city = null;

    public Province $province = Province::EastFlanders;

    // NO constructor, uses the parent constructor from BaseDTO
}

<?php

// If nothing is passed to the constructor, nothing gets populated
$createAddress = new createAddress();

// If an entity is passed, the matching properties will be populated
$addressDTO = new AddressDataTransferObject($address);

For example `public string $street` will be be filled from `$address->getStreet()`

// If a message extends from the addressDTO, it will also work
$updateAddress = new UpdateAddress($address);

// If one of the properties in the DTO is also a DTO, it will work recursively

This will save exactly 3.5 minutes for every new DTO that we use 😄

Deze PR is niet meer nodig. Heb er een bundle van gemaakt: https://github.com/dreadnip/smart-dto-bundle, met ook een attribuut. Op die manier is zowel het invoeren van data in het DTO, als het uitlezen naar een entity geautomatiseerd.
