Eloquent Meta-Relate

Extend Eloquent relationships to support implied polymorphism and merging

Installation

Use composer:

composer require danhunsaker/eloquent-meta-relate

Nothing to it!

Usage

Include the Danhunsaker\Eloquent\Traits\MetaRelate trait on any model you want to extend:

use Danhunsaker\Eloquent\Traits\MetaRelate;
use Illuminate\Database\Eloquent\Model;

class BaseModel extends Model
{
    use MetaRelate;
}

Implied Polymorphic Relationships

Now you can create implied polymorphic relationships simply by providing an array of class names, instead of a single class, wherever multiple models are part of the same relationship:

    public function files()
    {
        return $this->hasMany([
            'App\Models\Audio',
            'App\Models\Document',
            'App\Models\Image',
            'App\Models\Video',
        ]);
    }

Relationship Merging

You can also merge existing relationships:

    public function forkedTo()
    {
        return $this->hasMany('App\Models\Fork', 'original_id')->with('fork');
    }

    public function forkedFrom()
    {
        return $this->hasMany('App\Models\Fork', 'fork_id')->with('original');
    }

    public function allForks()
    {
        return $this->createMetaRelation()
            ->merge($this->forkedTo())
            ->merge($this->forkedFrom());
    }
