使用 Discord.py Rewrite 编写 Discord Bot

Question

所以目前我有一个 discord Bot，我想让它欢迎 #joining 中的任何新用户，并给他们昵称“[0] Member Name”。我没有收到任何错误，但这些功能都不起作用！

编辑：重新编写了一些代码，我现在遇到了这个错误：

编辑 2：仍然无法编辑昵称，但是当用户离开服务器时，我从函数中收到这些错误，以检查用户是否是员工。我没有从 message.author 收到错误，但是当消息作者离开时，我开始收到此错误。当有人离开服务器时，我尝试重置 message.author 但这没有帮助！我对如何阻止这些错误没有任何想法！

我会回复，因为您的代码中有多个错误并且很难放入评论中。如果您遇到其他错误，可以在此帖子下发表评论。

---

role = discord.utils.get(discord.Guild.roles, name="Member")

错误是您按名称成员检索角色的位置。最好通过 ID 获取角色，您可以使用 member.guild.get_role(630533613947060244) 来实现。错误是discord.Guild.roles 不是可迭代属性。

---

nick = discord.utils.get(str(member.nick))

不确定你的意图是什么，你可以使用nick = member.nick 来获取一个带有成员昵称的字符串。

---

要编辑您应该使用的昵称：

await member.edit(nick=f"[0] {member.display_name}")

---

AttributeError: 'User' 对象没有属性 'top_role'

您收到此错误是因为您想访问discord.User 实例上的top_role 属性，但只有discord.Member 定义了此属性。当有人离开服务器时，您将获得 User 实例而不是 Member 实例。

if isinstance(message.author, discord.Member):
  top_role = message.author.top_role
else:
  top_role = None   # top role not available, user has no roles
