python - access field of foregin key in django model function

Question

Let's say I have the following models.py:

from django.db import models

class Person(models.Model):
    name = models.CharField(max_length=100)
    father = models.ForeignKey(Person, on_delete=models.CASCADE)

And I need to add a function fullName(self) that will return a string, the person's name + space + the person's father name. What is the correct syntax to do this?

I tried the following but it doesn't work

from django.db import models

class Person(models.Model):
    name = models.CharField(max_length=100)
    father = models.ForeignKey(Person, on_delete=models.CASCADE)
    def fullName(self):
        return self.name + " " + self.father.name

pylint says: instance of 'ForeginKey' has no 'name' member
