 This project provides a `@hook` decorator as well as a base model and mixin to add lifecycle hooks to your Django models. Django's built-in approach to offering lifecycle hooks is [Signals](https://docs.djangoproject.com/en/dev/topics/signals/). However, my team often finds that Signals introduce unnecessary indirection and are at odds with Django's "fat models" approach.
 
 **Django Lifecycle Hooks** supports Python 3.5, 3.6, 3.7, 3.8 and 3.9, Django 2.0.x, 2.1.x, 2.2.x, 3.0.x and 3.1.x.
