Hi,
I want to implement hierarchy data model which is quite common in
Relational Data Model.
Let's say I have Employee model which has the relation to the boss which
link to the employee model itself.
It will look like this:
class Employee(models.Model):
empname = models.CharField(max_length=60)
boss = models.ForeignKey(Employee)
salary = models.integer()
Sample Data:
ID empname boss salary
--------------------------------------------------
1 albert null 10000
2 bert 1 5000
3 Chuck 1 5000
4 Donna 3 3000
5 Jack 3 2000
Albert is the root with Bert and Chuck under him and Chuck has Donna and
Jack under him.
I got an error when I tried to sync to the database where Django telling me
that the employee is not exist in the Foreign key part.
Is there any way to manipulate this situation?
Cheers,
Setiaman
