Django 3 Web Development Cookbook - Fourth Edition

Creating hierarchical categories with django-mptt

To illustrate how to deal with MPTT, we will build on top of the ideas app from Chapter 3, Forms and Views. In our changes, we will replace the categories with a hierarchical Category model and update the Idea model to have a many-to-many relationship with the categories. Alternatively, you can create the app from fresh, using only the content shown here, to implement a very basic version of the Idea model from scratch.
