我如何覆盖'@everyone'频道中的单个权限

Question

这是我的代码。它将所有其他权限设置为默认，并将更改将发送消息设置为false。

    @client.command()
    @commands.has_permissions(manage_channels=True)
    async def lock(ctx):
            await ctx.channel.set_permissions(ctx.guild.default_role, send_messages=False)
            await ctx.send('Channel locked.')
    @lock.error
    async def lock_error(ctx, error):
            if isinstance(error,commands.CheckFailure):
                    await ctx.send('You do not have permission to use this command!')

Answer 1

如果我正确理解了您的评论，则此代码应将所有其他权限保持不变，并且仅将您明确告知的权限更改为：

    @client.command()
    @commands.has_permissions(manage_channels=True)
    async def lock(ctx):
            overwrite = ctx.channel.overwrites_for(ctx.guild.default_role)
            overwrite.send_messages = False
            await ctx.channel.set_permissions(ctx.guild.default_role, overwrite=overwrite)
            await ctx.send('Channel locked.')
    @lock.error
    async def lock_error(ctx, error):
            if isinstance(error,commands.CheckFailure):
                    await ctx.send('You do not have permission to use this command!')
