[Django]-Django: Creating a Mixin for Reusable Model Fields

✅

Abstract models still need to inherit from model.Model to work correctly:

class TrackingFieldsMixin(models.Model):

Also instead of your active BooleanField I would add a deleted_on DateTimeField so you can record when the record was deleted. You can then just add properties on the instance to see if it’s active:

@property
def active(self):
    return self.deleted_on is None

and in queries and/or a custom manager:

Blog.objects.filter(deleted_on__isnull=True)
