PCM Metadata Bundle

Easily add scalar metadata to a Symfony entity via the use of a key-value interface.

Installation

1. Add this repository to composer.json:

"repositories": [
    {
        "type": "vcs",
        "url": "ssh://git@git.pcmdev.co.uk:2222/pcm-libraries/pcm-metadata-bundle.git"
    }
],

2. Install the bundle:

composer require pcm/metadata-bundle

3. If not set already add the following config to doctrine.yaml to prevent errors:

doctrine:
    orm:
        enable_native_lazy_objects: true

Usage

1. Use the MetadataTrait inside an entity:

class MyEntity
{
    use MetadataTrait;
}

2. Create and execute a new migration. The trait adds a metadata database field and as such we need to create a migration.
3. Access the metadata object with the readonly property metadata:

$entity->metadata->set("name", "PCM");
$entity->metadata->get("name"); // "PCM"
$entity->metadata->isSet("name"); // true

Like updating the value of a property normally, setting metadata values will not automatically update the database. You must call flush() from the EntityManager as usual when you wish to persist data.
