Re: Invalid pk \"1\" - object does not exist.

I guess you need to define first the id in models.CASCADE, 

When you try to insert as per your table definition it looks for the key on that table

manager = models.ForeignKey('self', null=True, related_name='employee',on_delete=models.CASCADE)
Hope this can be helpful 

Happy coding!!!

MANAGER = 'MGR'
STANDARD = 'STD'


EMPLOYEE_TYPES = (

(STANDARD, 'employee')

)


role = models.CharField(max_length=25, choices=EMPLOYEE_TYPES)
name = models.CharField(max_length=100, null=True, blank=True)
employee_id = models.CharField(max_length=100, null=True, blank=True)
manager = models.ForeignKey('self', null=True, related_name='employee',on_delete=models.CASCADE)
