在Django Rest框架中复制模型字段实例列表

from django.db import models
from django.utils import timezone
from django.contrib.auth.models import User

class MyModel(models.Model):
    field1 = models.CharField(max_length=100)
    field2 = models.IntegerField()
    field3 = models.DateTimeField(default=timezone.now)
    # 其他字段...

from rest_framework import serializers

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

# 复制模型字段实例列表的视图函数
def copy_model_instances(request):
    # 获取需要复制的模型实例列表
    instances = MyModel.objects.all()

    # 序列化模型实例列表
    serializer = MyModelSerializer(instances, many=True)

    # 复制模型实例列表
    copied_instances = serializer.save()

    # 返回复制后的模型实例列表
    return Response(MyModelSerializer(copied_instances, many=True).data)
