🎈 Usage

🔥 HasOneMetadata Trait

Add the HasOneMetadata trait to your model to enable a single metadata record:

use Waad\Metadata\Traits\HasOneMetadata;

class Company extends Model
{
    use HasOneMetadata;  // <--- Add this trait to your model
}

Some methods:

// Create metadata with array (only works if no metadata exists)
$company->createMetadata(['key' => 'value', 'another_key' => 'another_value']);

// Create metadata with collection
$company->createMetadata(collect(['key' => 'value']));

// Update existing metadata
$company->updateMetadata(['new_key' => 'new_value']);

// Delete the metadata
$company->deleteMetadata();

// Get metadata as array
$metadata = $company->getMetadata();

// Get metadata as collection
$metadataCollection = $company->getMetadataCollection();

---

🔥 HasManyMetadata Trait

Add the HasManyMetadata trait to your model to enable multiple metadata records:

use Waad\Metadata\Traits\HasManyMetadata;

class Post extends Model
{
    use HasManyMetadata;  // <--- Add this trait to your model

    // Enabled Append id with content metadata (default)
    public $metadataNameIdEnabled = true;

    // Custom Append key of id with metadata (default)
    public $metadataNameId = 'id';
}

see Configuration Append Id for more details

Some methods:

// Create metadata with array or collection
$post->createMetadata(['key1' => 'value1', 'key2' => 'value2']);
$post->createMetadata(collect(['key1' => 'value1', 'key2' => 'value2']));

// Update metadata by ID
$post->updateMetadata('{metadata_id}', ['new_key' => 'new_value']);

// Delete metadata by ID
$post->deleteMetadata('{metadata_id}');

// Get all metadata objects
$metadata = $post->metadata;
// or
$metadata = $post->metadata()->get();

// Get metadata by ID
$metadata = $post->getMetadataById('metadata_id');

// Get all metadata column pluck as array
$allMetadata = $post->getMetadata();

// Get all metadata column pluck as collection
$metadataCollection = $post->getMetadataCollection();

// Search in metadata
$searchResults = $post->searchMetadata('search_term');
