django-sharing 
django-sharing is a python sharing module written for django that handles object sharing. Don’t clone. Not stable.
Example
Basic example:
from django.contrib.contenttypes import generic
from django.db import models
from django_sharing.models import Share
class Car(models.Model):
"""A model that will be shared."""
# Add the reverse relation since the shared object is a generic object.
shares = generic.GenericRelation(Share)
Extending the sharing model:
from django.contrib.contenttypes import generic
from django.db import models
from django_sharing.models import AbstractShare
class CarShare(AbstractShare):
"""Extending the share model to add additional attributes."""
day = models.CharField(max_length=50)
class Car(models.Model):
"""A model that will be shared."""
# Add the reverse relation since the shared object is a generic object.
shares = generic.GenericRelation(CarShare)
