Tracking changes on a model

to audit a model you need import simple_audit and then register the model to be audited.

from django.db import models
import simple_audit


class Message(models.Model):

    title = models.CharField(max_length=50, blank=False)
    text = models.TextField(blank=False)

    def __unicode__(self):
        return self.text


class Owner(models.Model):

    name = models.CharField(max_length=50, blank=False)

    def __unicode__(self):
        return self.name


class VirtualMachine(models.Model):

    name = models.CharField(max_length=50, blank=False)
    cpus = models.IntegerField()
    owner = models.ForeignKey(Owner)
    so = models.CharField(max_length=100, blank=False)
    started = models.BooleanField()

    def __unicode__(self):
        return self.name


simple_audit.register(Message, Owner, VirtualMachine)

Advanced Usage (without httprequest or our middleware)

You can use django-simple-audit without an http request (for example in management command). In this situation there is no http request on thread context. To ensure gathering all modification on a single AuditRequest, you can specify it:

AuditRequest.new_request(path, user, ip)
try:
    # my code... in same thread
finally:
    AuditRequest.cleanup_request()

Tracking m2m fields changes

Tracking m2m fields changes is still experimental, but you can enable it with the following variable:

DJANGO_SIMPLE_AUDIT_M2M_FIELDS = True

You need to have at least one cache backend set in your django settings, otherwise the previous settings will be set to False.

CACHES = {
    'default': {
        'BACKEND': 'django.core.cache.backends.locmem.LocMemCache',
        'LOCATION': 'unique',
        'TIMEOUT': 300,
    }
}
