django-advanced-bulk-signals 0.1.0

Custom Django signals for update, bulk update/create operations with field tracking

django-bulk-signals

Custom signal support for Django bulk operations — with granular field-level diffing.

This library extends Django's signal framework to support bulk_create, bulk_update, and queryset update() operations. It also helps detect exactly which fields changed in each object.

✨ Features

• pre_bulk_create, post_bulk_create signals
• pre_bulk_update, post_bulk_update signals
• pre_update for regular .update() calls
• Field-level change tracking during bulk operations
• Decorators for easy multi-signal binding
• Drop-in replacement for your model Manager or QuerySet

🚀 Installation

pip install django-bulk-signals

🧠 Usage

1. Use the custom manager:

from django_bulk_signals.managers import CustomManager
from django.db import models

class Customer(models.Model):
    ...
    objects = CustomManager()

2. Connect to signals:

from django.dispatch import receiver
from django_bulk_signals.signals import pre_bulk_update

@receiver(pre_bulk_update, sender=Customer)
def customer_bulk_update_handler(sender, **kwargs):
    forward_data = kwargs.get("forward_data")
    print("Changed fields:", forward_data)

3. Signal Reference | Signal | Description | | ------------------ | ---------------------- | | pre_update | Before .update() | | pre_bulk_update | Before bulk_update() | | post_bulk_update | After bulk_update() | | pre_bulk_create | Before bulk_create() | | post_bulk_create | After bulk_create() |

🛠️ Tools Decorator

from django_bulk_signals.decorators import apply_signals

@apply_signals(Customer, pre_bulk_update, pre_update)
def handler(sender, **kwargs):
    ...
