django:如何在异步中使用"objects.all()“和"for”

from django.http import JsonResponse
from asgiref.sync import async_to_sync
from django.core.serializers import serialize

# 异步视图函数
async def async_view(request):
    # 异步查询
    queryset = await async_to_sync(MyModel.objects.all().values)()
    # 序列化查询结果
    data = serialize('json', queryset)
    return JsonResponse(data, safe=False)

from django.http import JsonResponse
from asgiref.sync import async_to_sync
from django.core.serializers import serialize

# 异步视图函数
async def async_view(request):
    # 异步查询
    queryset = MyModel.objects.all().iterator()
    # 异步迭代
    async for obj in queryset:
        # 处理每个对象
        # ...
    return JsonResponse({'message': 'Success'})
