Display Hierarchical Categories in Django Admin

[Rahul Chauhan]

Hi All,

I have a category Model like this one which is based on Adjacency List.

class Category(models.Model):

    name = models.CharField(blank=False, max_length=200)

    slug = models.SlugField(null=False)

    parent = models.ForeignKey('self', blank=True, null=True, related_name='child',on_delete=models.SET_NULL)

I want to display the model has hierarchical/nested structure in the Django admin. There are modules available such as TreeBeard or Django-MPTT but I dont want to use them.

Tried everything, but unable to achieve the above.

Any help in this direction will be highly appreciated.

Thanks.

Hello Rahul,

i Django MPTT tutorial you find in modely.py:

from django.db import models
from mptt.models import MPTTModel, TreeForeignKey

class Genre(MPTTModel):
    name = models.CharField(max_length=50, unique=True)
    parent = TreeForeignKey('self', on_delete=models.CASCADE, null=True, blank=True, related_name='children')

    class MPTTMeta:
        order_insertion_by = ['name']

This works. 

Regards

Thanks for the suggestion.

But I don't want to use any third party addon/module such as MPTT or Tree-Beard.
