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]: [<ProductAuditLogEntry: Product: My widget changed at 2011-02-25 06:04:29.292363>,
        <ProductAuditLogEntry: Product: My widget changed at 2011-02-25 06:04:24.898991>,
        <ProductAuditLogEntry: Product: My Gadget super changed at 2011-02-25 06:04:15.448934>,
        <ProductAuditLogEntry: Product: My Gadget changed at 2011-02-25 06:04:06.566589>,
        <ProductAuditLogEntry: Product: My Gadget created at 2011-02-25 06:03:57.751222>,
        <ProductAuditLogEntry: Product: My widget created at 2011-02-25 06:03:42.027220>]

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.
