Reusable Symfony Live Components for entity management. Provides tag and attachment management components that work with any Doctrine entity.

Features

• TagManager - Live Component for managing tags on any entity
• AttachmentManager - Live Component for file uploads and attachments
• SelectRelationship - Live Component for editing entity relationships and enums inline
• Generic interfaces - Work with your own Tag/Attachment entities
• Reusable traits - Easy implementation for entities

Installation

composer require kachnitel/entity-components-bundle

Quick Start

1. Create a Tag Entity

use Kachnitel\EntityComponentsBundle\Interface\TagInterface;

#[ORM\Entity]
class Tag implements TagInterface
{
    #[ORM\Id, ORM\GeneratedValue, ORM\Column]
    private ?int $id = null;

    #[ORM\Column(length: 64)]
    private string $value;

    #[ORM\Column(length: 64, nullable: true)]
    private ?string $displayName = null;

    #[ORM\Column(length: 32, nullable: true)]
    private ?string $category = null;

    // Implement TagInterface methods...
}

2. Make Your Entity Taggable

use Kachnitel\EntityComponentsBundle\Interface\TaggableInterface;
use Kachnitel\EntityComponentsBundle\Trait\TaggableTrait;

#[ORM\Entity]
class Product implements TaggableInterface
{
    use TaggableTrait;

    #[ORM\ManyToMany(targetEntity: Tag::class)]
    private Collection $tags;

    public function __construct()
    {
        $this->initializeTags();
    }
}

3. Use the TagManager Component

<twig:K:Entity:TagManager
    entity="{{ product }}"
    tagClass="App\\Entity\\Tag"
/>

Attachments Quick Start

1. Create an Attachment Entity

use Kachnitel\EntityComponentsBundle\Interface\AttachmentInterface;

#[ORM\Entity]
class UploadedFile implements AttachmentInterface
{
    #[ORM\Id, ORM\GeneratedValue, ORM\Column]
    private ?int $id = null;

    #[ORM\Column(length: 255)]
    private string $url;

    #[ORM\Column(length: 100)]
    private string $mimeType;

    #[ORM\Column(length: 255)]
    private string $path;

    // Implement AttachmentInterface methods...
}

2. Make Your Entity Attachable

use Kachnitel\EntityComponentsBundle\Interface\AttachableInterface;
use Kachnitel\EntityComponentsBundle\Trait\AttachableTrait;

#[ORM\Entity]
class Product implements AttachableInterface
{
    use AttachableTrait;

    #[ORM\ManyToMany(targetEntity: UploadedFile::class)]
    #[ORM\JoinColumn(onDelete: 'CASCADE')]
    #[ORM\InverseJoinColumn(unique: true)]
    private Collection $attachments;

    public function __construct()
    {
        $this->initializeAttachments();
    }
}

3. Implement FileHandlerInterface

use Kachnitel\EntityComponentsBundle\Interface\FileHandlerInterface;

class LocalStorageHandler implements FileHandlerInterface
{
    public function __construct(
        private string $uploadDirectory,
        private EntityManagerInterface $entityManager
    ) {}

    public function handle(UploadedFile $file): AttachmentInterface
    {
        $fileName = uniqid() . '.' . $file->guessExtension();
        $file->move($this->uploadDirectory, $fileName);

        $uploadedFile = new \App\Entity\UploadedFile();
        $uploadedFile->setUrl($fileName);
        $uploadedFile->setPath('/uploads/' . $fileName);
        $uploadedFile->setMimeType($file->getMimeType());

        $this->entityManager->persist($uploadedFile);

        return $uploadedFile;
    }

    public function deleteFile(AttachmentInterface $attachment): void
    {
        $filePath = $this->uploadDirectory . '/' . $attachment->getUrl();
        if (file_exists($filePath)) {
            unlink($filePath);
        }

        $this->entityManager->remove($attachment);
    }
}

4. Use the AttachmentManager Component

<twig:K:Entity:AttachmentManager
    entity="{{ product }}"
    attachmentClass="App\\Entity\\UploadedFile"
/>

Components

TagManager

Live Component for managing tags on entities.

Props:

• entity (TaggableInterface) - The entity to manage tags for
• tagClass (string) - FQCN of your Tag entity
• readOnly (bool) - Disable editing (default: false)

Events:

• toast.show - Dispatched on save/error with message
• modal.close - Dispatched after successful save

Usage:

<twig:K:Entity:TagManager
    entity="{{ product }}"
    tagClass="App\\Entity\\Tag"
/>

AttachmentManager

Live Component for managing file attachments on entities.

Props:

• entity (AttachableInterface) - The entity to manage attachments for
• attachmentClass (string) - FQCN of your Attachment entity
• readOnly (bool) - Disable file uploads/deletion (default: false)
• property (string) - Property name for attachments (default: 'attachments')

Events:

• toast.show - Dispatched on upload/delete/error with message

Usage:

<twig:K:Entity:AttachmentManager
    entity="{{ product }}"
    attachmentClass="App\\Entity\\UploadedFile"
/>

Required Service: You must implement and register a FileHandlerInterface service:

use Kachnitel\EntityComponentsBundle\Interface\FileHandlerInterface;
use Kachnitel\EntityComponentsBundle\Interface\AttachmentInterface;
use Symfony\Component\HttpFoundation\File\UploadedFile;

class LocalStorageHandler implements FileHandlerInterface
{
    public function handle(UploadedFile $file): AttachmentInterface
    {
        // Handle file upload, store it, create and return your Attachment entity
    }

    public function deleteFile(AttachmentInterface $attachment): void
    {
        // Delete the file from storage
    }
}

SelectRelationship

Live Component for inline editing of entity relationships and enum properties. Automatically detects whether the target property is an Entity or Enum and loads appropriate options.

Props:

• entity (object) - The entity containing the property to edit (required)
• property (string) - The property name to edit (required)
• role (string) - Role required to show the editable select (optional)
• viewRole (string) - Role required to show static display when edit role not granted (optional)
• placeholder (string) - Placeholder text for empty option (default: '-')
• displayProperty (string) - Property to display for options (default: 'name')
• valueProperty (string) - Property to use as value (default: 'id')
• filter (array) - Simple criteria for findBy() e.g., { active: true } (optional)
• repositoryMethod (string) - Custom repository method name e.g., 'findByRoles' (optional)
• repositoryArgs (array) - Arguments for custom repository method (optional)
• disableEmpty (bool) - Disable selection of empty option (default: false)
• disabled (bool) - Force disabled state (default: false)
• label (string) - Optional label text

Usage:

{# Basic usage with entity relationship #}
<twig:K:Entity:SelectRelationship
    :entity="order"
    property="region"
    role="ROLE_ORDER_REGION_EDIT"
    placeholder="- Select Region -"
    select:class="form-select"
/>

{# With enum property #}
<twig:K:Entity:SelectRelationship
    :entity="order"
    property="status"
    role="ROLE_ORDER_STATUS_EDIT"
/>

{# With simple filter #}
<twig:K:Entity:SelectRelationship
    :entity="order"
    property="assignedTo"
    :filter="{ active: true }"
    displayProperty="fullName"
/>

{# With custom repository method #}
<twig:K:Entity:SelectRelationship
    :entity="order"
    property="assignedTo"
    repositoryMethod="findByRoles"
    :repositoryArgs="[['ROLE_TERRITORY_MANAGER']]"
/>

Nested Attributes:

• select:* - Attributes for the <select> element (e.g., select:class="compact")
• static:* - Attributes for the static display <span> (e.g., static:class="text-muted")

Enum Support: Enums are automatically detected. If your enum implements a displayValue() method, it will be used for the option label:

enum OrderStatus: string
{
    case Pending = 'pending';
    case Shipped = 'shipped';

    public function displayValue(): string
    {
        return match ($this) {
            self::Pending => 'Awaiting Shipment',
            self::Shipped => 'Shipped',
        };
    }
}

Customization

All components use blocks that can be overridden:

<twig:K:Entity:TagManager entity="{{ product }}" tagClass="App\\Entity\\Tag">
    {% block tag_badge %}
        {# Custom tag display #}
        <span class="custom-tag">{{ tag.value }}</span>
    {% endblock %}
</twig:K:Entity:TagManager>

Requirements
