How to listen to events in Django?
If you want to listen for some event in django, you would use a signal. But, as these signals are object based, its more boiler plate to listen to multiple signals or to listen to a class of events.
Django-event-system utilizes gevent to build out an easy to use event system. This event system uses strings to track events and call event handlers. Why not just use django’s built in signals?
But django is based on signals, so in order to make it easier to just use events instead, django-event-system comes with Signal, to Event to help convert a signal to an event. Basically, this just connects a listener to a signal and then dispatches an event.
This of course begs the question “How to make UN-observed models dispatch events in Django?”
My answer is In order to make un-observed models dispatch events, use the Register, signals, and for function. This function juust takes a model class and will register all the signal objects and map them to an event based on the model’s name. Django commes with it’s own signal ideas.
