Laravel - Hierarchy in Eloquent model -

my database have hierarchy:

- manager:   - coordinator:     - supervisor:       - operator

this code, output "coordinator" belongs "manager":

manager::find(1)->coordinator()->get();

is possible "supervisor" belongs "coordinator" directly? example:

manager::find(1)->coordinator()->supervisor()->get();

sorry english, i'm brazilian

that possible, need define relationship in models. retrieve all "operators" specific "manager" doing:

manager::find(1)->coordinator->supervisor->operator;

in code, i'm using dynamic properites come eloquent orm.

when said 'you need defin relationships in models' doing following:

class manager extends eloquent {     public function coordinator()     {         return $this->hasmany('coordinator');     } }

then same coordinator has many supervisors , supervisor has many operators.
