Congrats, history is being recorded

HISTORY_GET_CURRENT_USER

# If true then the history object will be saved asynchronously using celery_app.
# WARNING: history recording uses pickle serializer.
HISTORY_ALLOW_CELERY

# If you are deleting objects programmatically,
# pass in a list of field names that store information about deleting the object
# to more accurately create a history object.
HISTORY_SOFT_DELETE_FIELDS

For example

1. Using soft delete model

# models.py
class Task(HistoryMixin):
  ...
  deleted_at = models.DateTimeField(null=True)
  ...

# settings.py
# Pass soft delete field in HISTORY_SOFT_DELETE_FIELDS
HISTORY_SOFT_DELETE_FIELDS = ['deleted_at']

2. If you use django-currentuser, pass get_current_user function to HISTORY_GET_CURRENT_USER

# settings.py
from django_currentuser.middleware import get_current_user

HISTORY_GET_CURRENT_USER = get_current_user
