Django 5 信号 asend：不可散列类型列表

Question

尝试使用 django 5 异步信号制作一个简短的示例。这是代码：

查看：

async def confirm_email_async(request, code):
    await user_registered_async.asend(
        sender=User,
    )
    return JsonResponse({"status": "ok"})

信号：

user_registered_async = Signal()

@receiver(user_registered_async)
async def async_send_welcome_email(sender, **kwargs):
    print("Sending welcome email...")
    await asyncio.sleep(5)
    print("Email sent")

错误轨迹是：

Traceback (most recent call last):
  File "C:\Users\karonator\AppData\Roaming\Python\Python311\site-packages\asgiref\sync.py", line 534, in thread_handler
    raise exc_info[1]
  File "C:\Users\karonator\AppData\Roaming\Python\Python311\site-packages\django\core\handlers\exception.py", line 42, in inner
    response = await get_response(request)

    response = await wrapped_callback(

    await user_registered_async.asend(
  File "C:\Users\karonator\AppData\Roaming\Python\Python311\site-packages\django\dispatch\dispatcher.py", line 250, in asend
    responses, async_responses = await asyncio.gather(
                                       ^^^^^^^^^^^^^^^
  File "C:\Program Files\Python311\Lib\asyncio\tasks.py", line 819, in gather
    if arg not in arg_to_fut:
       ^^^^^^^^^^^^^^^^^^^^^
TypeError: unhashable type: 'list'

将感谢任何帮助，已经伤透了我的头。 感谢您的宝贵时间。

此处拼写错误

asend

用

send
