Inverse of HasManyThrough relation is missing from Laravel's ORM. Belongs-To-Through extends Eloquent ORM with belongsToThrough relation.

Eloquent is awesome but it does have some problems. Checkout Plug!

Either PHP 5.6+ is required.

To get the latest version of Belongs-To-Through, simply require the project using Composer:

$ composer require znck/belongs-to-through

Instead, you may of course manually update your require block and run composer update if you so choose:

{
    "require": {
        "znck/belongs-to-through": "^2.2"
    }
}

Within your eloquent model class add following line

class User extends Model {
    use \Znck\Eloquent\Traits\BelongsToThrough;
    ...
}

Consider a blog application. In this app, a country can have many users and a user can have many articles. So, hasManyThrough provides easy way to access articles from a country.

class Country extends Model {
    use \Znck\Eloquent\Traits\BelongsToThrough;

    public function articles () {
        return $this->hasManyThrough(Article::class, User::class);
    }
}

If we are accessing the country of the article, then we have to use $article->user->country.

Class Article extends Model {
    use \Znck\Eloquent\Traits\BelongsToThrough;

    public function country() {
        return $this->belongsToThrough(Country::class, User::class);
    }
}

Now, the magic: $article->country

Going deeper, City -> District -> State -> Country

Class City extends Model {
	use \Znck\Eloquent\Traits\BelongsToThrough;

	public function country() {
		return $this->belongsToThrough(Country::class, [State::class, District::class]);
	}
}
