Django外键字段外键

Question

I have a model that looks like this

# models.py
from django.db import models


class Level_0(models.Model):
    Kode = models.CharField(max_length=10, null=False, blank=False, default="")

class Level_1(models.Model):
    Kode = models.CharField(max_length=10, null=False, blank=False, default="")
    Level_0= models.ForeignKey(Level_0, on_delete=models.CASCADE)

class Level_2(models.Model):
    Kode = models.CharField(max_length=10, null=False, blank=False, default="")
    Level_1 = models.ForeignKey(Level_1, on_delete=models.CASCADE)
    # Level_0 = ????????????

    # how do I create a connection to Level_0? 

What I want to have is a field in Level_2 that automatically connects to Level_0 through Level_1 . How do I add that field in my Level_2 model?

Answer 1

It is already indirectly related to Level_0.
To access Level_0 corresponding you go through Level_1
