Cache magic addresses two common scenarios for caching and cache invalidation for django models: instance caching and related objects caching.

Instance caching: Storing instances of objects in your cache layer as well as your database.

Related objects caching: Storing a collection of objects related to another object referenced by relational constraints (ForeignKey, ManyToMany, etc.)

pip install django-cache-magic

To start autocaching model instances, add a CacheController to your model:

from django.db import models
from cachemagic import CacheController

class myModel(models.Model):
    f1 = models.IntegerField()
    f2 = models.TextField()

    cache = CacheController()

myModel.cache.get(pk=27)

When using cachemagic, you should avoid django operations that update multiple rows at once, since these operations typically don't emit the signals that cachemagic relies on for cache invalidation. This includes methods like Queryset.update, Queryset.delete, and RelatedManager.clear

Big thanks to Travis Fischer for drafting a lot of documentation and tests!
