Django Rest Framework: Getting 'None' response when trying to access nested serializer data
I'm reviewing some code and Hey everyone, I'm running into an issue that's driving me crazy... I need some guidance on I'm working on a personal project and I'm working on a Django Rest Framework (DRF) project where I have a nested serializer setup. My model structure is such that I have a `Book` model that has a foreign key to an `Author` model. I want to include author details when I serialize a list of books, but I'm getting `None` for the author data in the response. Here's the relevant portion of my code: ```python # models.py from django.db import models class Author(models.Model): name = models.CharField(max_length=100) class Book(models.Model): title = models.CharField(max_length=100) author = models.ForeignKey(Author, related_name='books', on_delete=models.CASCADE) ``` ```python # serializers.py from rest_framework import serializers from .models import Book, Author class AuthorSerializer(serializers.ModelSerializer): class Meta: model = Author fields = ['name'] class BookSerializer(serializers.ModelSerializer): author = AuthorSerializer() class Meta: model = Book fields = ['title', 'author'] ``` When I query my API endpoint for the list of books, it returns an empty `author` field like this: ```json [ { "title": "Sample Book", "author": null } ] ``` I've checked my database and confirmed that the `Book` entries have valid `Author` foreign keys. I've also tried adding a `__str__` method to the `Author` model to ensure it returns a string representation, but that didn't help. I've also made sure to include `AuthorSerializer` in the `BookSerializer`, and everything seems correct. Is there something obvious that I might be missing? Maybe an issue with how DRF handles nested serializers? I'm using Django 3.2 and DRF 3.12. Any insights would be greatly appreciated! I'm working on a web app that needs to handle this. I'd really appreciate any guidance on this. For context: I'm using Python on macOS. What am I doing wrong? This is happening in both development and production on macOS. I'm working with Python in a Docker container on Ubuntu 22.04.
