Unexpected KeyError when using Django's get_or_create with nested serializers
I can't seem to get I'm deploying to production and I'm sure I'm missing something obvious here, but This might be a silly question, but I'm sure I'm missing something obvious here, but I'm working with Django Rest Framework (version 3.12) and trying to use `get_or_create` within a nested serializer to avoid duplicate entries in my database... The scenario is that I have a `Book` model with a foreign key to an `Author` model. When I attempt to create or get a book along with its author, I encounter a `KeyError` for the author field. Here’s the relevant part of my serializer code: ```python class AuthorSerializer(serializers.ModelSerializer): class Meta: model = Author fields = ['id', 'name'] class BookSerializer(serializers.ModelSerializer): author = AuthorSerializer() class Meta: model = Book fields = ['id', 'title', 'author'] def create(self, validated_data): author_data = validated_data.pop('author') author, created = Author.objects.get_or_create(**author_data) return Book.objects.create(author=author, **validated_data) ``` When I send a POST request with the following payload: ```json { "title": "New Book", "author": { "name": "John Doe" } } ``` I get this traceback: ``` KeyError: 'name' ``` I’ve verified that the `author` data is correctly passed to `get_or_create`, but it seems that the `author_data` dictionary does not contain the expected keys. After adding some print statements, I confirmed that `author_data` is indeed empty when I reach the `get_or_create` line. I suspect this might be due to how the serializer is validating the data, but I haven’t found a clear solution. Any insights into what might be causing this scenario or how to properly handle nested serializers in this context would be greatly appreciated! My development environment is macOS. Am I missing something obvious? Any help would be greatly appreciated! This is part of a larger application I'm building. The project is a microservice built with Python. Has anyone else encountered this? Am I missing something obvious? I'm developing on Windows 10 with Python. Am I missing something obvious? Has anyone else encountered this?
