Eloquent HasManyDeep Package

December 20, 2019 / Eric L. Barnes

The Laravel Eloquent HasManyDeep Package is an extended version of Laravel Eloquent’s HasManyThrough that allows relationships with unlimited intermediate models. It includes support for many-to-many and polymorphic relationships.

As an example of how this package is useful to pretend you have a setup where you want to get all comments for all posts, by users in a specific country. It might look something like this:

Country → hasMany → User → hasMany → Post → hasMany → Comment

Granted this gets pretty complicated, but with this package, you can define the relationship like the following:

class Country extends Model
{
    use \Staudenmeir\EloquentHasManyDeep\HasRelationships;

    public function comments()
    {
        return $this->hasManyDeep('App\Comment', ['App\User', 'App\Post']);
    }
}

Then you’ll be able to call Country::first()->comments to get all the comments which keeps the familiar Laravel syntax.

To take this a step further, Povilas Korop from Laravel Daily also created a review video covering this package:
