Fundamentals

This library is a bridge between eboreum/caster and doctrine/orm.

This library handles formatting of entity classes, which either:

• Has the attribute Doctrine\ORM\Mapping\Entity (commonly written as #[ORM\Entity]).
• Has the annotation Doctrine\ORM\Mapping\Entity (commonly written as @ORM\Entity in the docblock of a class).

ID properties (i.e. Doctrine\ORM\Mapping\Id or @ORM\Id as either attribute or annotation) are always identified and included. May be used with Eboreum\Caster\Contract\DebugIdentifierAttributeInterface and subsequently the attribute Eboreum\Caster\Attribute\DebugIdentifier, to provide additional information about the entity. The latter is especially useful in the following scenarios (often during debugging):

• The entity has not yet been persisted and thus it has not yet received an ID (e.g. through auto generation). By having #[DebugIdentifier] on other properties, this may help providing crucial debugging information.
• Some other, non-ID property is essential for e.g. debugging purposes.
• Some desire to increase verbosity on an entity when it is being formatted.

For help with Doctrine annotations and/or attributes and their uses, please see:

• Attributes reference: https://www.doctrine-project.org/projects/doctrine-orm/en/2.11/reference/attributes-reference.html
• Annotations reference: https://www.doctrine-project.org/projects/doctrine-orm/en/2.11/reference/annotations-reference.html#annotations-reference

Examples

Basics

Code:

<?php

declare(strict_types=1);

namespace SomeCustomNamespace_9c95fb43;

use Doctrine\ORM\Mapping as ORM;
use Eboreum\Caster\Attribute\DebugIdentifier;
use Eboreum\Caster\Caster;
use Eboreum\Caster\Collection\Formatter\ObjectFormatterCollection;
use Eboreum\Caster\Contract\DebugIdentifierAttributeInterface;
use Eboreum\CasterDoctrineEntityFormatter\EntityFormatter;

#[ORM\Entity]
class User implements DebugIdentifierAttributeInterface
{
    #[ORM\Id]
    public ?int $id = null;

    #[DebugIdentifier]
    public string $name = 'foo';
}

$user = new User();

$caster = Caster::create()->withCustomObjectFormatterCollection(new ObjectFormatterCollection([
    new EntityFormatter(),
]));

echo $caster->cast($user) . "\n";

$user->id = 42;
$user->name = 'bar';

echo "\n";
echo $caster->cast($user) . "\n";

Output:

\SomeCustomNamespace_9c95fb43\User {$id = (null) null, $name = (string(3)) "foo"}

\SomeCustomNamespace_9c95fb43\User {$id = (int) 42, $name = (string(3)) "bar"}

Render DebugIdentifier only when ID is not set

The wording "is not set" means the ID can be either uninitialized or null.

Why?

Often, when you have an ID of something, other information may end up just creating noise. This feature allows you to reduce such noise.

Code:

<?php

declare(strict_types=1);

namespace SomeCustomNamespace_fd813f94;

use Doctrine\ORM\Mapping as ORM;
use Eboreum\Caster\Attribute\DebugIdentifier;
use Eboreum\Caster\Caster;
use Eboreum\Caster\Collection\Formatter\ObjectFormatterCollection;
use Eboreum\Caster\Contract\DebugIdentifierAttributeInterface;
use Eboreum\CasterDoctrineEntityFormatter\EntityFormatter;

#[ORM\Entity]
class User implements DebugIdentifierAttributeInterface
{
    #[ORM\Id]
    public ?int $id;

    #[DebugIdentifier]
    public string $name = 'foo';
}

$user = new User();

$entityFormatter = new EntityFormatter();
$entityFormatter = $entityFormatter->withIsRenderingDebugIdentifierOnlyWhenIdHasNotBeenSet(true);

$caster = Caster::create()->withCustomObjectFormatterCollection(new ObjectFormatterCollection([
    $entityFormatter,
]));

echo $caster->cast($user) . "\n";

$user->id = null;

echo "\n";
echo $caster->cast($user) . "\n";

$user->id = 42;

echo "\n";
echo $caster->cast($user) . "\n";

Output:

\SomeCustomNamespace_fd813f94\User {$id = (uninitialized), $name = (string(3)) "foo"}

\SomeCustomNamespace_fd813f94\User {$id = (null) null, $name = (string(3)) "foo"}

\SomeCustomNamespace_fd813f94\User {$id = (int) 42}
