权限覆盖不更改不和谐频道权限。不和谐.py

技术标签:
【中文标题】权限覆盖不更改不和谐频道权限。不和谐.py【英文标题】：Permission Overwrite not changing the discord channel permissions. Discord.py 【发布时间】：2020-05-07 06:46:30 【问题描述】：好的，所以我正在创建一个票务系统，当频道创建时我将创建频道的用户保存在JSON中，当票证即将关闭时，我读取成员并尝试更改频道权限这样他们就无法发送消息但可以阅读并且可以做出反应。但是当我这样做时它不起作用。完全没有错误。
代码的确切位置：
if str(ticket_closure_reaction.emoji) == "✅":
ticket_creator_dict = await self.read_json_to_dict("ticket_creator_ids.json", ctx.channel)
ticket_creator_user_id = ticket_creator_dict.get(str(ticket_channel.id))

【问题讨论】：
我也有同样的问题 问题没有包含足够的信息来重新创建问题。此外，代码示例包含无关信息。随着 OP 的消失，如果有人有类似的问题，则需要有人根据guidelines 发布一个新问题，以便可以回答。但是，首先检查“How do you use permission overwrites? Discord.py Rewrite”是否没有回答任何此类尝试。 【参考方案1】：我真的不知道发生了什么样的问题，但可能是它无法检测到反应。因此，不要在 check_create_ticket_reaction 函数中使用实际的表情符号，而是使用表情符号 ID：
reaction.emoji.id == <insert the id here>
【讨论】：
等一下，答案出错了，我的意思是reaction.emoji.id == 您可以编辑自己的答案，请不要在cmets中更正自己的答案。以上是关于权限覆盖不更改不和谐频道权限。不和谐.py的主要内容，如果未能解决你的问题，请参考以下文章
