The right place to keep my signals.py file in a Django project

Question

Based on Django\'s documentation I was reading, it seems like signals.py in the app folder is a good place to start with, but the problem I\'m facing is that wh

Answer 1

An alternative is to import the callback functions from signals.py and connect them in models.py:

signals.py

def pre_save_callback_function(sender, instance, **kwargs):
    # Do stuff here

model.py

# Your imports here
from django.db.models.signals import pre_save
from yourapp.signals import pre_save_callback_function

class YourModel:
    # Model stuff here
pre_save.connect(pre_save_callback_function, sender=YourModel)

Ps: Importing YourModel in signals.py will create a recursion; use sender, instead.

Ps2: Saving the instance again in the callback function will create a recursion. You can make a control argument in .save method to control it.
