'TextChannel' 对象不可迭代 |通道检查不起作用

Question

您好，我正在尝试检查频道是否已经存在，而不是在每次会员发送 modmail 请求时都创建一个新频道。我得到的错误是

File "C:\Users\User\Desktop\Build 1.0.2\cogs\modmail.py", line 145, in on_message
if get(modmailchannel, name=f"{message.author.name.lower()}{message.author.discriminator}"):
File "C:\Users\User\AppData\Local\Programs\Python\Python37\lib\site-packages\discord\utils.py", line 271, in get
for elem in iterable:
TypeError: 'TextChannel' object is not iterable
enter code here

不确定原因或方法不正确。创建的频道名称是用户名和鉴别符。我想要实现的是，如果该频道已经存在，请不要在同一频道中创建另一个 channel/post。

这是我正在使用的代码：

@commands.Cog.listener()

        # not a DM, or it's just the bot itself
        return
    
    bucket = self._cd.get_bucket(message)
    retry_after = bucket.update_rate_limit()
    seconds = bucket.update_rate_limit()
    seconds = round(seconds, 2)
    hours, remainder = divmod(int(seconds), 3600)
    minutes, seconds = divmod(remainder, 60)
    if retry_after:
        pass

Answer 1

而不是 if get(modmailchannel, name=f"{message.author.name.lower()}{message.author.discriminator}"): 使用：

if modmailchannel.name == f"{message.author.name.lower()}{message.author.discriminator}":
