============================

django-audit-log

Tracking changes to django models.

  • Model fields for keeping track of the user and session that created and modified a model instance.
  • Abstract model class with fields
    created_by
    and
    modified_by
    fields.
  • A model manager class that can automatically track changes made to a model in the database.
  • Support for Django 1.6 and 1.7, South migrations, Django 1.7 migrations and custom User classes.
  • Python 3 and 2.x support

The documentation can be found here

Tracking full model history on M2M relations is not supported yet. Version 0.3.0 onwards is tested with Django 1.6. It should work with older versions of Django, but may break things unexpectedly!

Quickstart Guide

Install it with pip from PyPi::

pip install django-audit-log

Add

audit_log.middleware.UserLoggingMiddleware
to your
MIDDLEWARE_CLASSES
::
MIDDLEWARE_CLASSES = (
'django.contrib.sessions.middleware.SessionMiddleware',
'django.middleware.common.CommonMiddleware',
'django.middleware.csrf.CsrfViewMiddleware',
'django.contrib.auth.middleware.AuthenticationMiddleware',
'django.contrib.messages.middleware.MessageMiddleware',
'django.middleware.clickjacking.XFrameOptionsMiddleware',
'audit_log.middleware.UserLoggingMiddleware',
)

To just track who created or edited a model instance just make it inherit from

AuthStampedModel
::
from audit_log.models import AuthStampedModel

class WarehouseEntry(AuthStampedModel): product = models.ForeignKey(Product) quantity = models.DecimalField(max_digits = 10, decimal_places = 2)

This will add 4 fields to the

WarehouseEntry
model:
  • created_by
    - A foreign key to the user that created the model instance.
  • created_with_session_key
    - Stores the session key with which the model instance was first created.
  • modified_by
    - A foreign key to the user that last saved a model instance.
  • modified_with_session_key
    - Stores the session key with which the model instance was last saved.

If you want to track full model change history you need to attach an

AuditLog
manager to the model::
from django.db import models
from audit_log.models.fields import LastUserField
from audit_log.models.managers import AuditLog


class ProductCategory(models.Model): name = models.CharField(max_length=150, primary_key = True) description = models.TextField()

audit_log = AuditLog()

class Product(models.Model): name = models.CharField(max_length = 150) description = models.TextField() price = models.DecimalField(max_digits = 10, decimal_places = 2) category = models.ForeignKey(ProductCategory)

audit_log = AuditLog()

You can then query the audit log::

In [2]: Product.audit_log.all()
Out[2]: [,
        ,
        ,
        ,
        ,
        ]

Note: This project was not maintained actively for a while. One of the reasons was that I wasn't receiving email notifications from GitHub. The other reason: We were using it just on a couple of projects that were frozen to old versions of Django. If you need any help with the project you can contact me by email directly if I don't respond to your GitHub issues. Feel free to nudge me over email if you have a patch for something. You can find my email in the AUTHORS file.
