You can also just write a Celery task to do your async stuff and trigger it
from signals.py

Hi,

Signals are also good for decoupling things.

For example you want to do some post save action for third party models.

RE: Query Regarding Django Signals

[Matthew Pava]

The advantage with the signals is that you can put all that code in one place.  
You may have different views that are saving the same model, and it isn’t DRY 
to have to put that same code in multiple locations.

Hello Community

I was puzzled by the fact that if django signals are not asynchronous why do we 
use them as in when ever i want some trigger on post_save can't  i simply write 
that particular trigger in the same function that handles the request for 
saving a new object in django views..?
as in :

def handlerequest(Request):
save instance to db
   Do the work i would do in the method handling the signal post_save

Query Regarding Django Signals

[Nipun Arora]

Hello Community 

I was puzzled by the fact that if django signals are not asynchronous why 
do we use them as in when ever i want some trigger on post_save can't  i 
simply write that particular trigger in the same function that handles the 
request for saving a new object in django views..?
as in :


def handlerequest(Request):
save instance to db 
   Do the work i would do in the method handling the signal post_save
