列表正在工作，但post在Django Rest框架中的嵌套序列化程序中不起作用

from rest_framework import serializers

class NestedListSerializer(serializers.ListSerializer):
    def create(self, validated_data):
        # 处理validated_data并创建列表对象
        # 返回创建的列表对象
        pass

from rest_framework import serializers

class MyModelSerializer(serializers.ModelSerializer):
    nested_list = serializers.ListField(child=serializers.CharField())

    class Meta:
        model = MyModel
        fields = ['nested_list']

    def create(self, validated_data):
        nested_list_data = validated_data.pop('nested_list')
        instance = MyModel.objects.create(**validated_data)
        nested_list_serializer = self.fields['nested_list']
        nested_list_serializer.child = serializers.CharField()  # 设置嵌套字段的序列化器
        nested_list = nested_list_serializer.create(nested_list_data)
        instance.nested_list.set(nested_list)
        return instance
