使用Serialzer使用POST方法更新Django模型实例

# models.py
from django.db import models

class Book(models.Model):
    title = models.CharField(max_length=100)
    author = models.CharField(max_length=100)
    publication_date = models.DateField()

# serializers.py
from rest_framework import serializers
from .models import Book

class BookSerializer(serializers.ModelSerializer):
    class Meta:
        model = Book
        fields = ['id', 'title', 'author', 'publication_date']

# views.py
from rest_framework.views import APIView
from rest_framework.response import Response
from rest_framework import status
from .models import Book
from .serializers import BookSerializer

class BookDetailView(APIView):
    def post(self, request, pk):
        try:
            book = Book.objects.get(pk=pk)
        except Book.DoesNotExist:
            return Response(status=status.HTTP_404_NOT_FOUND)

        serializer = BookSerializer(book, data=request.data)
        if serializer.is_valid():
            serializer.save()
            return Response(serializer.data)
        return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)
