如何修复代码，使其允许我获取输入命令的用户id？

Question

您好，我目前正在尝试使用MongoDB在线服务为我的Discord机器人制作一个带有经济系统的机器人，但是我似乎无法让我的代码使用这两个工具！平衡或平衡！“工作”命令，因为它不断出现以下错误：

错误：

我阅读了您的代码，发现了一些问题，请尝试我从您的代码中修改的代码

@bot.command()
async def balance(ctx):
    await open_account(ctx.author)
    discorduserid = ctx.author.id

    document = collection.find_one({"userid":discorduserid})
    print(document)

    wallet_amt = document["points"]

    em = discord.Embed(title = f"{ctx.author.name}'s balance", colour = discord.Colour.red())
    em.add_field(name = "Wallet", value = wallet_amt)
    await ctx.send(embed = em)

@bot.command()
@commands.cooldown(1, 43200, commands.BucketType.user)
async def work(ctx):
    await open_account(ctx.author)

    discorduserid = ctx.author.id

    earnings = random.randrange(500)

    await ctx.send(f"You went to work and earned {earnings} coins!")
    doc = collection.find_one({"userid":discorduserid}})

    total_earnings = doc["points] + earnings
    

    results = collection.update_one({"userid":discorduserid}, {"$set":{"points":total_earnings}})

@work.error
async def work_error(ctx, error):
    if isinstance(error, commands.CommandOnCooldown):
        timerem = str(timedelta(error.retry_after/28800)).split(".")[0]
        msg1 = 'This command is on cooldown, please try again in '
        msg2 = msg1 + timerem
        await ctx.send(msg2)
    else:
        raise error

async def open_account(user: discord.User):
    discorduserid = user.id

    doc = collection.find_one({"userid": discorduserid})

    if doc != None:
        print(doc)
    else:
        print(doc)
        newentry = {"userid":discorduserid, "points":0}
        collection.insert_one(new_entry)

我希望这有帮助。祝你有美好的一天！
