In Django, how do you make a model refer to itself?

Question

Assume we have class Employee. I want to have a field which references a different instance of the same class.

How to write this? How about the followi

Answer 1

You can reference other models by name (using a string, including package), instead of by the class directly:

So, if your Employee class is in the hr app:

class Employee(models.model):
   other_employee = models.ForeignKey('hr.models.Employee', null=True, blank=True)
