在序列化Django中过滤数据

# 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 import generics
from .models import Book
from .serializers import BookSerializer

class BookList(generics.ListAPIView):
    serializer_class = BookSerializer

    def get_queryset(self):
        queryset = Book.objects.all()
        # 假设我们要根据出版日期过滤书籍
        publication_date = self.request.query_params.get('publication_date')
        if publication_date is not None:
            queryset = queryset.filter(publication_date=publication_date)
        return queryset
