Unable to get children of a category

[mayuroks]

I am using django-categories to implement music related app. I want artist as my category and his/her songs as children

models.py

from django.db import models
from django_extensions.db.fields import AutoSlugField
from categories.models import CategoryBase

class Artist(CategoryBase):
cat = models.CharField(max_length=255, blank=True)

def __unicode__(self):
    return self.name

class Song(models.Model):
title = models.CharField(max_length=255,)
slug = AutoSlugField(populate_from='title', unique=True)
description = models.TextField()
cat = models.ForeignKey(Artist, blank=True)

def __unicode__(self):
    return self.title

In templates, artist_details.html

{% extends 'base_post.html' %}
{% load category_tags %}
{% block page_content %}

{{ artist.name }}

{% if artist.children.count %}

Subcategories

{% for child in artist.children.all %}

• {{ child }}

{% endfor %}

{% endif %}

The template is getting rendered coz I can see artist's name. But i am unable to fetch the children. I checked the docs but I could not find much stuff related to fetching children.

There is data for both models in my DB, I added relevant info via admin interface. Can anyone tell me what I am missing ?

I think you've planned your schema out incorrectly. From the looks of it, you really don't need to have Artist subclass CategoryBase, you could just subclass models.Model.

You have a typical Many-to-One relationship and should be able to get the songs using artist.song_set.all

True children in Categories are the same model, not two different models. Does that answer your question, or did I misunderstand something?
