python - 阻止机器人创建同名的重复 channel |不和谐.py

Question

我正在为我的 discord 机器人创建票证工具，但用户可以通过在那里使用react来创建无限制的票证。但是，我希望机器人向该用户发送 dm，以提醒他们他已经有一张未结票。

到目前为止，这是我尝试过的方法，但根本不起作用:

guild = await bot.fetch_guild(id)
channels = guild.text_channels
duplicate = False
name = f"{payload.member.name}'s ticket"
for channel in channels:
    if name == channel.name:
        duplicate = True
        break

if duplicate:
    await payload.member.send("You already have an open ticket")
    return
else:
    await category.create_text_channel(name, topic= topic, permission_synced= True)
    await ticket_channel.set_permissions(payload.member, read_messages= True, send_messages= True) 

Answer 1

文本 channel 名称中不能有空格和引号(它也会被转换为小写)，像这样的名称 Name's ticket 将被转换为 names-tickets.

name = f"{payload.member.name.lower()}s-ticket"
for channel in channels:
    if name == channel.name:
        duplicate = True
        break

您还可以大大简化代码，您可以使用 any 函数代替 for 循环

duplicate = any(name == channel.name for channel in channels)
if duplicate:
    return await payload.member.send("You already have an open ticket")
