英文:
Django: TypeError: XXX() got multiple values for argument 'chat_id'
问题
我正在使用Django和Celery，并且遇到了这个错误：
TypeError: get_response()的参数'chat_id'收到了多个值
我通过以下方式调用该函数：
i = get_response.delay(chat_id=chat_id, is_first_message=is_first_message, question=question, user_id=user_id)
函数的头部如下：
@shared_task(bind=True)
def get_response(chat_id: int, is_first_message: bool, question: str, user_id: int) -> str:
我尝试运行了print(chat_id)，但这只确认了该字段是一个单一的整数。
编辑。完整的跟踪信息：

I'm using Django with Celery and getting this error:
TypeError: get_response() got multiple values for argument 'chat_id'
I'm calling the function via:
i = get_response.delay(chat_id=chat_id, is_first_message=is_first_message,question=question,user_id=user_id)
and the function header is:
@shared_task(bind=True)
def get_response(chat_id: int, is_first_message: bool,
question:str,user_id:int) -> str:
I tried running a print(chat_id) but this only confirmed the field was a single integer.

应该将bind=True移除，的确：
@shared_task # 🖘 no bind=True
def get_response(
chat_id: int, is_first_message: bool, question: str, user_id: int
) -> str:
# ...
pass
确实，对于bound tasks [celery-doc]，任务实例作为第一个参数传递，因此你应该要么将self（或task或其他一些参数）添加为第一个参数，要么移除bind=True，因为你似乎在函数中并未使用它。
英文:
You should leave the bind=True out, indeed:
<pre><code><b>@shared_task</b> # 🖘 no <b>bind=True</b>
def get_response(
chat_id: int, is_first_message: bool, question: str, user_id: int
) -> str:
# …
pass</code></pre>
indeed, with bound tasks <sup>[celery-doc]</sup> the task instance is passed as first parameter, so you should either add self (or task or some other parameter) as first parameter, or remove the bind=True, since you don't seem to use it in your function anyway.
