django-audit-fields
===================

This module has two model mixins that when used with a Django model adds a group of audit fields updated when a model instance is created and modified. This is one part of a strategy to be compliant with guidelines such as `Good Clinical Practice (GCP) <https://www.ema.europa.eu/en/human-regulatory-overview/research-development/compliance-research-development/good-clinical-practice>`_, `21 CFR part 11 <https://www.ecfr.gov/current/title-21/chapter-I/subchapter-A/part-11>`_, `EU GDPR <https://gdpr.eu/>`_, `UK GDPR <https://ico.org.uk/for-organisations/data-protection-and-the-eu/data-protection-and-the-eu-in-detail/the-uk-gdpr/>`_, and the `South African POPI Act <https://popia.co.za>`_. See the full list below of fields below.

This module includes `django-revision`_, which tracks the source code revision, and is best used together with `django-simple-history`_.

As of version 1.1.0, `edc-utils`_ is no longer a dependency of ``django-audit-fields``.

Documentation: `django-audit-fields.readthedocs.io <https://django-audit-fields.readthedocs.io/>`_

Requirements: DJ5.2+, py3.12+

Older versions
--------------
* <=0.3.3 (DJ 3.1, py 3.7, 3.8)
* >=0.3.4 (DJ 3.2+, py 3.9+)
* >=0.3.14 (DJ4.2, py3.11) includes locale


Installation
------------

.. code-block:: bash

    pip install django-audit-fields

Add ``django-audit-fields`` to INSTALLED_APPS

.. code-block:: python

    INSTALLED_APPS = [
        "...",
        "django_audit_fields.apps.AppConfig",
        "..."]

Usage
-----

Add model fields to track creation and modification dates, users and more on save.


Declare your model using ``AuditModelMixin``

.. code-block:: python

    from django_audit_fields.models import AuditModelMixin
    from simple_history.models import HistoricalRecords

    class MyModel(AuditModelMixin,  models.Model):

        history = HistoricalRecord()

        class Meta(AuditModelMixin.Meta):
            pass

Preferably, use a UUID as primary key by declaring your model using ``AuditUuidModelMixin``

.. code-block:: python

    from django_audit_fields.models import AuditUuidModelMixin
    from simple_history.models import HistoricalRecords

    class MyModel(AuditUuidModelMixin, models.Model):

        history = HistoricalRecord()

        class Meta(AuditUuidModelMixin.Meta):
            pass


Model mixins ``AuditModelMixin`` and ``AuditUuidModelMixin``
------------------------------------------------------------

The model mixin ``AuditUuidModelMixin`` sets the ``id`` fields to a ``UUIDField`` instead of an integer field.

Model mixins ``AuditModelMixin`` and ``AuditUuidModelMixin`` add audit fields:

+-------------------+-----------------+----------------------------+
| Field             | Field class     | Update event               |
+===================+=================+============================+
| created           | DateTimeField   | only set on pre-save add   |
+-------------------+-----------------+----------------------------+
| modified          | DateTimeField   | updates on every save      |
+-------------------+-----------------+----------------------------+
| user_created      | CharField       | only set on pre-save add   |
+-------------------+-----------------+----------------------------+
| user_modified     | CharField       | updates on every save      |
+-------------------+-----------------+----------------------------+
| hostname_created  | CharField       | only set on pre-save add   |
+-------------------+-----------------+----------------------------+
| hostname_modified | CharField       | updates on every save      |
+-------------------+-----------------+----------------------------+
| locale_created    | CharField       | only set on pre-save add   |
+-------------------+-----------------+----------------------------+
| locale_modified   | CharField       | updates on every save      |
+-------------------+-----------------+----------------------------+
| revision          | RevisionField*  | updates on every save      |
+-------------------+-----------------+----------------------------+


* RevisionField is from django-revision. See `django-revision.readthedocs.io <https://django-revision.readthedocs.io/>`_.
