如何在Django Rest框架序列化程序中捕获sql错误？

from rest_framework import serializers
from django.db import DatabaseError

class MySerializer(serializers.ModelSerializer):
    def to_representation(self, instance):
        try:
            return super().to_representation(instance)
        except DatabaseError as e:
            # 在此处处理捕获到的SQL错误
            # 可以记录日志或返回自定义错误信息等
            return {'error': str(e)}

from rest_framework.views import APIView
from .serializers import MySerializer
from .models import MyModel

class MyView(APIView):
    def get(self, request):
        queryset = MyModel.objects.all()
        serializer = MySerializer(queryset, many=True)
        return Response(serializer.data)
