POPO - Plain Old Python Object

messaging.py

class Messaging(object):
    def __init__(self, user, sender, receiver, message):
        self.user = user
        self.sender = sender
        self.receiver = receiver
        self.message = message
    
    def send(self):
        required_points = self.get_required_points()
        if required_points > self.user.points:
            raise Exception('Not enough points')
        
        return self.backend.send(self.sender, self.receiver, self.message)

hi @k4ml, I'm new to django/python and I'm looking for articles, books, etc, about the strategy of using pure python objects to place complex business logic. My biggest difficult now is about django project structures. Where this kind of classes should be placed?

do you have any sources related to this?

hi gcaraciolo
Service objects are plain old Python objects (POPOs) that encapsulate a
service or interactions with a system. They are usually kept in a separate
file named services.py or utils.py.

I'm in 2024 and enjoying this thread. Thank you!
