django-eventlog
===============

django-eventlog is a very simple event logger you can use to track certain
actions in your code. Events are stored in a Django model and can be viewed
in the Django Admin.

Usage Example:

.. code-block:: python

from eventlog import EventGroup

e = EventGroup() # Start a new Event Group
e.info('About to send 1000 mails.', # Trigger an Event
initiator='Mailer Daemon')
try:
# ... sending 1000 mails
e.info('All emails sent!', # Trigger an Event in the same group,
initiator='Mailer Daemon') # so they are combined in the admin.
except Exception:
e.error('There was an error sending the emails.',
initiator='Mailer Daemon')


You can reuse an event group by specifying a group name and attach optional data.
Data must be JSON serializable.

.. code-block:: python

from eventlog import EventGroup

def purchase():
e = EventGroup(group_id=f"Order {self.order.pk}")
e.info("Sent order to Shopify", data={"items": [1, 2, 3]})

def subscribe_newsletter():
e = EventGroup(group_id=f"Order {self.order.pk}")
e.info("User subscribed to newsletter on checkout", data={"email": "user@example.com"})


Events can be grouped in a "Event Group" and when hovering over one item
in the admin, all events of the same group are highlighted:

:scale: 100 %

The details view of an event will list all other events of this group so you
can track the progress:

.. note::

While looking similar, it's not intended to be a replacement for your
regular Python ``logging`` facility, rather an addition to it.

django-eventlog stores it's data in a regular database model, so each log entry
will trigger a SQL Insert. Therefore you should be careful using it in high
performance and/or high volume environments.
