从序列化Django REST API的字段中排除特定实例

from rest_framework import serializers
from myapp.models import MyModel

class MyModelSerializer(serializers.ModelSerializer):
    class Meta:
        model = MyModel
        fields = '__all__'

class MyModelSerializer(serializers.ModelSerializer):
    class Meta:
        model = MyModel
        fields = '__all__'

    def to_representation(self, instance):
        # 检查是否是需要排除的特定实例
        if instance.some_field == 'excluded_value':
            return None  # 返回 None 来排除此实例

        return super().to_representation(instance)

from myapp.models import MyModel
from myapp.serializers import MyModelSerializer
from rest_framework.generics import ListAPIView

class MyModelListView(ListAPIView):
    queryset = MyModel.objects.all()
    serializer_class = MyModelSerializer
