Django REST Framework: Parsing Nested JSON in a PUT Request with Custom Serializer Validation
I'm trying to figure out I'm currently working on a Django REST Framework application, and I'm having trouble parsing nested JSON data in a PUT request. My API endpoint is set up to update a user profile, which includes a nested structure for 'preferences'. The incoming JSON looks like this: ```json { "username": "john_doe", "email": "john@example.com", "preferences": { "notifications": true, "theme": "dark" } } ``` I'm using a custom serializer for the user profile, and I want to ensure that the nested 'preferences' dictionary is validated properly. However, when I send the PUT request, I receive the following behavior: ``` ValidationError: {'preferences': [ErrorDetail(string='This field is required.', code='required')]} ``` It seems like the serializer isn't recognizing the 'preferences' field as part of the valid input. Here's the relevant part of my serializer code: ```python from rest_framework import serializers from .models import UserProfile class PreferencesSerializer(serializers.Serializer): notifications = serializers.BooleanField(required=True) theme = serializers.ChoiceField(choices=['light', 'dark'], required=True) class UserProfileSerializer(serializers.ModelSerializer): preferences = PreferencesSerializer(required=True) class Meta: model = UserProfile fields = ['username', 'email', 'preferences'] extra_kwargs = { 'username': {'required': True}, 'email': {'required': True} } ``` In my view, I have the following code to handle the PUT request: ```python from rest_framework import status from rest_framework.response import Response from rest_framework.views import APIView class UserProfileView(APIView): def put(self, request, *args, **kwargs): serializer = UserProfileSerializer(data=request.data) if serializer.is_valid(): serializer.save() return Response(serializer.data, status=status.HTTP_200_OK) return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST) ``` I've confirmed that the data being sent is in the correct format. I also tried removing the `required=True` from the `preferences` field, but that didn't resolve the scenario. Can anyone guide to figure out why the nested preferences field is causing a validation behavior? Any insights into how to debug this would be greatly appreciated! Has anyone else encountered this?
