Django signals not firing when using bulk_create for related objects
Does anyone know how to I've been struggling with this for a few days now and could really use some help. I'm converting an old project and I'm working on a project and hit a roadblock. I'm getting frustrated with I'm stuck trying to I can't seem to get I've searched everywhere and can't find a clear answer..... This might be a silly question, but I'm relatively new to this, so bear with me... I'm experiencing an issue where Django signals are not firing when I perform a `bulk_create` operation on a related model. I have a `Book` model that has a foreign key relationship with an `Author` model. When I create multiple `Book` instances associated with the same `Author` using `bulk_create`, I expect the `post_save` signal for `Book` to be triggered for each instance created. However, it seems that the signals are not being executed at all. Here's a simplified version of my models: ```python from django.db import models class Author(models.Model): name = models.CharField(max_length=255) class Book(models.Model): title = models.CharField(max_length=255) author = models.ForeignKey(Author, on_delete=models.CASCADE) ``` And the signal I have defined: ```python from django.db.models.signals import post_save from django.dispatch import receiver @receiver(post_save, sender=Book) def book_saved(sender, instance, created, **kwargs): if created: print(f'New book created: {instance.title}') ``` I'm invoking `bulk_create` like this: ```python author = Author.objects.create(name='Author Name') books = [Book(title='Book 1', author=author), Book(title='Book 2', author=author)] Book.objects.bulk_create(books) ``` When I run this code, I don't see any output from the signal. I've confirmed that the books are being created in the database, but the signal-handler function does not get called. I’ve also tried using `save()` for each `Book` instance, and the signal fires correctly in that case. Is there a reason why Django doesn't fire signals for `bulk_create`? Is there a workaround to achieve the same behavior? Any insights would be greatly appreciated! I'm working on a web app that needs to handle this. Has anyone else encountered this? My development environment is Linux. What am I doing wrong? My team is using Python for this mobile app. What are your experiences with this? Could this be a known issue? I'm developing on Linux with Python. I'm working with Python in a Docker container on Ubuntu 22.04. Any feedback is welcome! This is my first time working with Python 3.11. Has anyone else encountered this? My team is using Python for this web app. I'd really appreciate any guidance on this.
