Django 3 Web Development Cookbook - Fourth Edition

How to do it...

Pass QuerySet of your hierarchical categories to the template and then use the {% recursetree %} template tag as follows:

1. Create a view that loads all of the categories and passes them to a template:

# myproject/apps/categories/views.pyfrom django.views.generic import ListViewfrom .models import Categoryclass IdeaCategoryList(ListView):    model = Category    template_name = "categories/category_list.html"    context_object_name = "categories"

2. Create a template with the following content to output the hierarchy of categories:

{# categories/category_list.html #}{% extends "base.html" %}{% load mptt_tags %}{% block content %}    <ul class="root">        {% recursetree categories %}            <li>                {{ node.title }}                {% if not node.is_leaf_node %}                    <ul  ...
