Eloquent Service Injection

Simple trait to inject services into Eloquent models via a property.

Laravel's Eloquent models do not support constructor service injection. This trait aims to provide a simple and unified way of injection services into Eloquent models. It is doing that by using a property to define services, in a similar way how other model options can be defined (think $casts or $with for attribute casting and eager loading).

Requirements

• PHP >= 5.6.0
• Laravel >= 5.1 or Lumen >= 5.1

Installation

Add the package to your repository with Composer.

composer require mrgrain/eloquent-service-injection

Usage

Extend your models by using the trait:

namespace Mrgrain\EloquentServiceInjection;

class Comment extends Model {
    use ServiceInjectionTrait;
}

To always include the trait, add it to a base model all your models are extending from.

Add the services to be injected into the $inject property.

class Comment extends Model {
    use ServiceInjectionTrait;
    
    public $inject = [
        'storage' => Illuminate\Contracts\Filesystem\Filesystem::class
    ];
}

Use the array key, to access the service anywhere.

class Comment extends Model {
    use ServiceInjectionTrait;

    public $inject = [
        'storage' => Illuminate\Contracts\Filesystem\Filesystem::class
    ];
    
    public function storeAttachment($path, $contents)
    {
        $this->storage->put($path, $contents);
    }
}

Other usages

Wheres the trait has been designed for Eloquent models, it can be used in pretty much any class. Add and use it the same way as with models.
