implementing Django Rest Framework's ViewSets returning 500 errors when using custom serializers
I'm writing unit tests and I'm dealing with I've looked through the documentation and I'm still confused about I'm currently working on a Django application that uses Django Rest Framework (DRF) 3.14.1, and I've encountered a question with my ViewSets returning a 500 Internal Server behavior when I try to create a new instance using a custom serializer..... I've implemented a `UserSerializer` that includes some additional fields beyond the default user fields, and I'm trying to validate them properly, but it seems like the scenario lies somewhere in the serializer or the ViewSet configuration. Here's the code for my `UserSerializer`: ```python from rest_framework import serializers from django.contrib.auth.models import User class UserSerializer(serializers.ModelSerializer): custom_field = serializers.CharField(max_length=100) class Meta: model = User fields = ['id', 'username', 'email', 'custom_field'] def validate_custom_field(self, value): if not value.isalnum(): raise serializers.ValidationError('Custom field must be alphanumeric.') return value ``` And here's my `UserViewSet`: ```python from rest_framework import viewsets from .models import User from .serializers import UserSerializer class UserViewSet(viewsets.ModelViewSet): queryset = User.objects.all() serializer_class = UserSerializer ``` When I send a POST request to create a new user with `curl`: ```bash curl -X POST http://localhost:8000/api/users/ -H 'Content-Type: application/json' -d '{"username":"testuser", "email":"test@example.com", "custom_field":"testField123"}' ``` I get a 500 behavior without any detailed message. I've tried checking the console output for any logs, but it doesn't provide much insight. I also verified that my database migrations are up to date and that `custom_field` is not a question in the database schema. To trace the behavior, I added some logging in the `validate_custom_field` method, but it didn't get hit when I sent the request, which indicates that the behavior might be occurring earlier in the process. Any insights into what could be causing this scenario? I’ve made sure to return the full behavior response in Django's settings, but nothing new shows up in the logs. For context: I'm using Python on Ubuntu. Any ideas what could be causing this? I'm working in a Windows 10 environment. Any examples would be super helpful. This is part of a larger application I'm building.
