Permission System for Discord.py Bot

Question

I am in the process of making a discord bot using discord.py and asyncio. The bot has commands like kick and ban which obviously should not be avai

Answer 1

The tips found the accepted answer may not work:

1. There may be compatibility issues with the rewrite version of the discord.py library and the pre-rewrite versions, which remain non-obsolete, non-deprecated, and still in use.

2. The bot should also check it's own permissions, to rule out one reason for the error.

3. If there is an error, or permissions for the bot itself are invalid, the bot should say something, correct?

4. Something needs to be implemented to prevent the bot from attempting to work this command in a DM or group context. It will almost always error.

I propose the following solution for pre-rewrite (assuming you use the command extension):

import discord
from discord.ext import commands
import time
@bot.command(pass_context=True,description="Kicks the given member. Please ensure both the bot and the command invoker have the permission 'Kick Members' before running this command.")
async def kick(ctx, target:discord.Member):
    """(GUILD ONLY) Boot someone outta the server. See 's!kick' for more."""
    if not str(ctx.message.channel).startswith("Direct Message with "):
        msg=await bot.say("Checking perms...")
        time.sleep(0.5)
        if ctx.message.server.me.server_permissions.kick_members:
            if ctx.message.author.server_permissions.kick_members:
                await bot.edit_message(msg,new_content="All permissions valid, checking issues with target...")
                time.sleep(0.5)
                if target==ctx.message.server.owner:
                    await bot.edit_message(msg, new_content="All permissions are correct, but you're attempting to kick the server owner, whom you can't kick no matter how hard you try. Whoops!")
                else:
                    if target==ctx.message.server.me:
                        await bot.edit_message(msg, new_content="Whoops! All permissions are corrent, but you just tried to make me kick myself, which is not possible. Perhaps you meant someone else, not poor me?")
                    else:
                        await bot.edit_message(msg, new_content="All permissions correct, and no issues with target being self or server owner, attempting to kick.")
                        time.sleep(2)
                        try:
                            await bot.kick(target)
                            await bot.edit_message(msg, ":boom: BAM! ***kicc'd***")
                        except Exception:
                            await bot.edit_message(msg, new_content="I was unable to kick the passed member. The member may have a higher role than me, I may have crashed into a rate-limit, or an unknown error may have occured. In that case, try again.")
            else:
                await bot.edit_message(msg, new_content="I've the correct permissions, {}, but you do not. Perhaps ask for them?").format(ctx.message.author.mention)
        else:
            await bot.edit_message(msg, new_content="I'm just a poor bot with no permissions. Could you kindly grant me the permission `Kick Members`? Thanks! :slight_smile:")
    else:
        await bot.say("'Tis a DM! This command is for servers only... try this again in a server maybe? :slight_smile:")
