How to make a directory with a large level of nesting of categories?

Question

Django

Hello everyone
. Such a question, but how to make a directory in Django with nesting of subcategories by 4-5 levels? I usually made a field with a category selection, but how to nest categories?

Answer 1

You can use django-treebeard or django-mptt
dajngopackages to help you

Answer 2

You can add a parent field to the category, which will refer to the category class itself:

class Category(models.Model):
    ...
    parent = models.ForeignKey('self', blank=True, null=True, verbose_name="Родитель", related_name='children')

Answer 3

For such purposes, I would start a mongo (MongoDB) or something similar and store the tree there, without any joins and other things, you take the tree with one request and all the required information is already in the RDBMS
