Django ORM ManyToMany Field Not Saving Related Objects Properly
Quick question that's been bugging me - I'm working with an scenario with saving related objects in a ManyToManyField in Django... I have two models, `Author` and `Book`, where a book can have multiple authors and an author can write multiple books. The models are defined like this: ```python class Author(models.Model): name = models.CharField(max_length=100) class Book(models.Model): title = models.CharField(max_length=200) authors = models.ManyToManyField(Author) ``` When I try to save a `Book` instance with a list of `Author` instances, it seems like the authors are not being linked correctly. Here is the code I’m using to create and save a book: ```python # Creating authors author1 = Author.objects.create(name='Author One') author2 = Author.objects.create(name='Author Two') # Creating a book and linking authors book = Book(title='Sample Book') book.save() # This should save the book but not yet link authors book.authors.add(author1, author2) # Adding authors ``` After executing this code, I check the database and see that the authors are not linked to the book. When I retrieve the book using `Book.objects.get(title='Sample Book')`, the `authors` field is empty. I also tried using the `bulk_create` method to add multiple authors simultaneously, but it resulted in the same scenario. I’ve made sure that I am running Django 3.2 and have the necessary migrations applied. I’m not seeing any behavior messages, but it feels like the relationship isn’t being saved correctly. Is there something I’m missing or doing incorrectly in this process? Any help would be appreciated! I'm working on a service that needs to handle this.
