DoctrineEntityDtoBundle

About

The Symfony bundle provides a simple mechanism to convert Doctrine entities to DTO objects.

Requirements

PHP 8.3 or higher
Symfony 7.0 or higher
Doctrine 2

1. Installation

Install danilovl/doctrine-entity-dto-bundle package by Composer:

composer require danilovl/doctrine-entity-dto-bundle

Add the DoctrineEntityDtoBundle to your application's bundles if it does not add automatically:

<?php
// config/bundles.php

return [
    // ...
    Danilovl\DoctrineEntityDtoBundle\DoctrineEntityDtoBundle::class => ['all' => true]
];

2. Configuration

After installing the bundle, you can change configuration settings in the danilovl_doctrine_entity_dto.yaml.

Default configuration.

danilovl_doctrine_entity_dto:
  isEnableEntityDTO: false
  isEnableEntityRuntimeNameDTO: false
  isAsEntityDTO: false
  entityDTO: []
  
  isEnableScalarDTO: false
  isAsScalarDTO: false
  scalarDTO: []

3. Usage

3.1 Entity DTO

The DoctrineEntityDtoBundle automatically creates doctrine hydration for every entity class names if isEnableEntityDTO is true.

danilovl_doctrine_entity_dto:
  isEnableEntityDTO: true

You can add a control attribute isAsEntityDTO that only entities with this attribute will create DTO hydration.

danilovl_doctrine_entity_dto:
  isEnableEntityDTO: true
  isAsEntityDTO: true

#[ORM\Table(name: 'cheque')]
#[AsEntityDTO]
class Cheque

You can choose your own array of entities.

danilovl_doctrine_entity_dto:
  isEnableEntityDTO: true
  entityDTO:
    - App\Domain\Cheque\Entity\Cheque

Or you can combine your list with the attribute control.

danilovl_doctrine_entity_dto:
  isEnableEntityDTO: true
  isAsEntityDTO: true
  entityDTO:
    - App\Domain\Cheque\Entity\Cheque

You only need to use the alias name of the entity and add the entity class name to the getResult method.

Alias name selects all data in the table.

$result = $this->entityManager
    ->getRepository(Cheque::class)
    ->baseQueryBuilder()
    ->select('cheque, city, shop, product')
    ->leftJoin('cheque.shop', 'shop')
    ->leftJoin('shop.city', 'city')
    ->leftJoin('cheque.orderList', 'orderList')
    ->leftJoin('orderList.product', 'product')
    ->setMaxResults(10)
    ->getQuery()
    ->getResult(Cheque::class);

The result will be the same as Doctrine's result but without a connection to the unit of work.

array:2 [▼
  0 => App\Domain\Cheque\Entity\Cheque {#1107 ▼
    +price: "105.4"
    +chequeNumber: "0119-201703119-02-9380"
    +shop: App\Domain\Shop\Entity\Shop {#1091 ▶}
    +currency: ? App\Domain\Currency\Entity\Currency
    +orderList: ? Doctrine\Common\Collections\Collection
    +walletTransaction: ? App\Domain\Wallet\Entity\WalletTransaction
    #id: 4
    #date: DateTime @1489878000 {#1083 ▶}
    #createdAt: DateTime @1489878000 {#1081 ▶}
    #updatedAt: DateTime @1489878000 {#1071 ▶}
  }
  1 => App\Domain\Cheque\Entity\Cheque {#1094 ▼
    +price: "311.27"
    +chequeNumber: "0019-20170318-05-9278"
    +shop: App\Domain\Shop\Entity\Shop {#1141 ▶}
    +currency: ? App\Domain\Currency\Entity\Currency
    +orderList: ? Doctrine\Common\Collections\Collection
    +walletTransaction: ? App\Domain\Wallet\Entity\WalletTransaction
    #id: 5
    #date: DateTime @1489791600 {#1142 ▶}
    #createdAt: DateTime @1489791600 {#1139 ▶}
    #updatedAt: DateTime @1489791600 {#1138 ▶}
  }
]

If you want the name of the DTO class to be different from the entity class name, use the parameter isEnableEntityRuntimeNameDTO.

It creates the name based on the pattern %sRuntimeDTO.

Note that this feature utilizes the eval function.

array:2 [▼
  0 => ChequeRuntimeDTO {#1107 ▼
    +price: "105.4"
    +chequeNumber: "0119-201703119-02-9380"
    +shop: App\Domain\Shop\Entity\Shop {#1091 ▶}
    +currency: ? App\Domain\Currency\Entity\Currency
    +orderList: ? Doctrine\Common\Collections\Collection
    +walletTransaction: ? App\Domain\Wallet\Entity\WalletTransaction
    #id: 4
    #date: DateTime @1489878000 {#1083 ▶}
    #createdAt: DateTime @1489878000 {#1081 ▶}
    #updatedAt: DateTime @1489878000 {#1071 ▶}
  }
  1 => ChequeRuntimeDTO {#1094 ▼
    +price: "311.27"
    +chequeNumber: "0019-20170318-05-9278"
    +shop: App\Domain\Shop\Entity\Shop {#1141 ▶}
    +currency: ? App\Domain\Currency\Entity\Currency
    +orderList: ? Doctrine\Common\Collections\Collection
    +walletTransaction: ? App\Domain\Wallet\Entity\WalletTransaction
    #id: 5
    #date: DateTime @1489791600 {#1142 ▶}
    #createdAt: DateTime @1489791600 {#1139 ▶}
    #updatedAt: DateTime @1489791600 {#1138 ▶}
  }
]

3.2 Scalar DTO

If isAsScalarDTO is true, it automatically scans the src project directory for every file, trying to find a class with the attribute AsScalarDTO.

When you use the AsScalarDTO attribute, the results of namespaces are cached for prod environment.

danilovl_doctrine_entity_dto:
  isEnableScalarDTO: true
  isAsScalarDTO: true

You can declare your own list of namespaces for the DTO class in the configuration without using the attribute.

danilovl_doctrine_entity_dto:
  isEnableScalarDTO: true
  scalarDTO:
    - App\Domain\Cheque\EntityDTO\ChequeDTO

Alternatively, you can combine the attribute and list. The final result will be merged.

danilovl_doctrine_entity_dto:
  isEnableScalarDTO: true
  isAsScalarDTO: true
  scalarDTO:
    - App\Domain\Cheque\EntityDTO\ChequeDTO

Example of ChequeDTO.

<?php declare(strict_types=1);

namespace App\Domain\Cheque\EntityDTO;

use Danilovl\DoctrineEntityDtoBundle\Attribute\AsScalarDTO;

#[AsScalarDTO]
class ChequeDTO
{
    public function __construct(
        public readonly int $id,
        public readonly string $chequeNumber
    ) {}
}

Before using scalar select, you need to set the class name to the static property $dtoClass.

After call getResult, ScalarHydration set to null static $dtoClass parameter.

It is a limitation of Doctrine hydration that when you use scalar select, the Doctrine ResultSetMapping is empty.

ScalarHydration::$dtoClass = ChequeDTO::class;

$this->entityManager
    ->getRepository(Cheque::class)
    ->baseQueryBuilder()
    ->select('cheque.id, cheque.chequeNumber')
    ->setMaxResults(2)
    ->getQuery()
    ->getResult(ChequeDTO::class);

As a result, the select query returns an array of DTO objects.

array:2 [▼
  0 => App\Domain\Cheque\EntityDTO\ChequeDTO {#1065 ▼
    +id: 4136
    +chequeNumber: "165791"
  }
  1 => App\Domain\Cheque\EntityDTO\ChequeDTO {#1066 ▼
    +id: 5838
    +chequeNumber: "539349913"
  }
]

4. Other

For example, when you use knplabs/knp-components to create a paginator and set a Doctrine query to pagination, if you want to create DTO objects as a result, simply add the class using the setHydrationMode method.

$this->paginator->paginate($query->setHydrationMode(class::class));

If use Gedmo Translatable DoctrineExtensions additionally needed setHint.

$query->setHint(Query::HINT_CUSTOM_OUTPUT_WALKER, TranslationWalker::class);
$query->setHydrationMode(Product::class);
