This package is a replacement for the builtin Django_ Signals which you can define all of the events and actions in the model itself and add conditions to determine when they are triggered. With the help of this package you can track the changed field previous and current values and determine when an action should trigger by creating an event with the decorators in the model.

A simple example will be:

.. code-block:: python

class User(EventActionModel):
    is_active = models.BooleanField()

    @PostSaveEvent(field='is_active', prev=False, now=True)
    def user_deactivated(self):
        # logic

    @PostCreateEvent()
    def post_create(self):
        # logic

.. end docs include
