Audit log
=========

Wagtail provides a mechanism to log actions performed on its objects. Common activities such as page creation, update, deletion,
locking and unlocking, revision scheduling and privacy changes are automatically logged at the model level.

The Wagtail admin uses the action log entries to provide a site-wide and page specific history of changes. It uses a
registry of 'actions' that provide additional context for the logged action.

The audit log-driven Page history replaces the revisions list page, but provide a filter for revision-specific entries.

.. note:: The audit log does not replace revisions

To provide additional ``Page`` logging for your site or package, invoke the :meth:`~PageLogEntryManger.log_action` manager method
via ``PageLogEntry.objects.log_action(object_instance, action)`` and register a ``register_log_actions`` hook to
describe your action (see :ref:`register_log_actions`).

.. note:: When adding logging, you need to log the action or actions that happen to the ``Page``. For example, if the
        user creates and publishes, there should be a "create" entry and a "publish" entry. Or, if the user copies a
        published page and chooses to keep it published, there should be a "copy" and a "publish" entry for new page.

You can provide additional metadata by passing additional parameters:

- ``user`` - a user object.
- ``data`` - a data dictionary, stored as JSON
- ``title`` - by default, Wagtail will attempt to use ``get_admin_display_title`` or the string representation of the passed object.

.. code-block:: python

    # mypackage/views.py
    from wagtail.core.models import PageLogEntry

    def copy_for_translation(page):
        # ...
        page.copy(log_action='mypackage.copy_for_translation')

    def my_method(request, page):
        # ..
        # Manually log an action
        data = {
            'make': {'it': 'so'}
        }
        PageLogEntry.objects.log_action(
            instance=page, action='mypackage.custom_action', user=request.user, data=data
        )

To log actions for your non-page model, you can create a class that inherits from ``BaseLogEntry`` with the appropriate
linking.
