Laravel query builder for recursive results? E.g. id, parent_id

Question

So I have data structured like this:

id|parent_id|name
1 |null     |foo
2 |1        |bar
3 |2        |baz

So basically foo->bar->ba

I've created a package that uses common table expressions (CTE) to implement recursive relationships: https://github.com/staudenmeir/laravel-adjacency-list

You can use the ancestors relationship to get all parents of a model recursively:

class YourModel extends Model
{
    use \Staudenmeir\LaravelAdjacencyList\Eloquent\HasRecursiveRelationships;
}

$allParents = YourModel::find($id)->ancestors;
