Multiple table inheritance in Laravel 5.1

Hi, I've read some comments about how to implement multiple table inheritance in Laravel, but I'm confused. In this thread (http://stackoverflow.com/questions/33462292/table-inheritance-in-laravel/38616585), I noted that a table inheritance was implemented. However, Laravel 5.1 documentation explains about "Polymorphic Relations" (https://laravel.com/docs/5.1/eloquent-relationships#polymorphic-relations).

This is my scenario: A "Person" can be a "Student", "Teacher" and/or "Candidate". The same person can be Student and Teacher at the same time, for example. This is a way to implement the models I think (I do not know if it is correct):

class Person extends Model {
        public function teacher(){
                  return $this->hasOne(Teacher::class);
  }
         public function student(){
                 return $this->hasOne(Student::class);
         }
          public function candidate(){
               return $this->hasOne(Candidate::class);
} 
}

class Student extends Person {
    public function person(){
        return $this->belongsTo(Person::class);
    }
}

class Teacher extends Person {
    public function person(){
        return $this->belongsTo(Person::class);
    }
}

class Candidate extends Person {
    public function person(){
        return $this->belongsTo(Person::class);
    }
}

In the database, I would create the tables:

• Person (id, name, phone)
• Student (person_id, etc)
• Teacher (person_id, etc)
• Candidate (person_id, etc)

This way, I do not use Polymorphic Relations as Laravel 5.1 explains. Any suggestions about the best way to accomplish this?

Thank you very much.
