Usage

Nette installation

extensions:
    hydrator: Nettrine\Hydrator\DI\HydratorExtension

Basic usage

$entity = $hydrator->toFields(Entity::class, [
	'name' => 'foo',
	'field' => 'value',
]);

$entity = $hydrator->toFields($entityObj, [
	'name' => 'foo',
	'field' => 'value',
]);

Entity to an array

$array = $hydrator->toArray($entity);

Custom ArrayAccessor

Used to read from or write to an object's property.

class CustomPropertyAccessor implements IPropertyAccessor {
	
	public function get(object $object, string $property) { ... }
	
	public function set(object $object, string $property, $value): void { ... }
	
}

Nette registration:

hydrator:
    propertyAccessor: CustomPropertyAccessor

Adapters

Do you have custom rules of getting or setting an object's value? The existing features don't suit your needs? Adapters can be used to extend the functionality.

All the adapters have to be registered via addFieldAdapter or addArrayAdapter methods.

In Nette:

hydrator:
    adapters:
        fields:
            - Nettrine\DoctrineHydration\Adapters\CallbackFieldAdapter
            - Nettrine\DoctrineHydration\Adapters\TargetEntityFieldAdapter
        array:
            - Nettrine\DoctrineHydration\Adapters\JoinArrayAdapter
            - Nettrine\DoctrineHydration\Adapters\ManyToOneAdapter

ArrayAdapter

IArrayAdapter interface is implemented. Built-in adapters:

ManyToOneArrayAdapter

All object relations are converted to an ID.

$entity = new Assoc class {
	public $id = 42;
	
	public $foo = 'foo';
	
	/**
	 * @ManyToOne(targetEntity="Assoc")
	 */
	public $assoc;
};

$entity->assoc->id++;

$array = $hydrator->toArray($entity);

$array === [
	'id' => 42,
	'assoc' => 43,
];

JoinArrayAdapter

Object association is converted to an array.

$entity = new Assoc class {
	public $id = 42;
	
	public $foo = 'foo';
	
	/**
	 * @ManyToOne(targetEntity="Assoc")
	 */
	public $assoc;
};

$entity->assoc->id++;

$array = $hydrator->toArray($entity, [
	'joins' => [
		'assoc' => 'foo'
	]
]);

$array === [
	'id' => 42,
	'assoc' => 'foo',
];

FieldAdapter

IFieldAdapter interface is implemented. Built-in adapters:

CallbackFieldAdapter

A callback can be used:

$hydrator->toFields($obj, [
	'name' => 'foo',
], [
	'callbacks' => [
		'name' => function (FieldArgs $args) {
		    $args->value = ucfirst($args->value);
		},
	] 
]);

The value of the $name property is now Foo.

TargetEntityFieldAdapter

In case of an association the corresponding entity will be found:

$hydrator->toFields($obj, [
	'assoc' => 42, // Item with the value of 42 will be found
]);

Creating a custom adapter

Say we have the following image custom type annotation:

/**
 * @ORM\Column(type="image")
 */

and we want to automatically save the image during hydration:

class CustomFieldAdapter implements IFieldAdapter {

	public function __construct(IImageStorage $storage) { ... }

	public function isWorkable(FieldArgs $args): bool {
		// Apply only when the type is `image` and it is not an assocation
		return !$args->metadata->isAssociation($field) && $args->metadata->getFieldMapping($field)['type'] === 'image';
	}

	public function work(FieldArgs $args): void {
		$image = new Image($value);
		if ($args->hasSettingsSection('images')) {
			$image->setName($args->getSettingsSection('images'));
		}
		$this->storage->save($image);
		
		$args->value = $image;
	}

}

Registration in Nette:

hydrator:
    adapters:
        fields: 
            - CustomFieldAdapter

Usage:

$hydrator->toFields($obj, [
	'avatar' => __DIR__ . '/avatar.png',
], [
	'images' => [
		'avatar' => 'foo.png',
	]
]);
