Cannot register commands with cogs

[aurkaxi]

import discord, os
from discord.ext import commands


bot = discord.ext.commands.Bot(command_prefix="&", intents=discord.Intents.all())

class Test(commands.Cog):
	def __init__(self, bot):
		self.bot = bot

	@commands.command()
	async def ping(self, ctx, name: str = None):
		await ctx.send("Pong")

bot.add_cog(Test(bot))

token = os.environ['TOKEN']
bot.run(token)

while i send message "&ping" nothing happens. on the console the log is

ERROR    discord.ext.commands.bot Ignoring exception in command None
discord.ext.commands.errors.CommandNotFound: Command "ping" is not found

In this video it works completely fine.

As of discord.py v2.0, Bot.add_cog is a coroutine function. You must await it. For detailed information on asynchronous setup, See this section on migrating guide.

So i made a folder 'cogs' created two files inside them. one in 'init.py' which is blank. another one is test.py with

from discord.ext import commands
class Test(commands.Cog):
	def __init__(self, bot):
		self.bot = bot

	@commands.command()
	async def ping(self, ctx, name: str = None):
		await ctx.send("Pong")

async def setup(bot):
	await bot.add_cog(Test(bot))

and my main.py is

import discord, os
from discord.ext import commands
from keep_alive import keep_alive

bot = discord.ext.commands.Bot(command_prefix="&", intents=discord.Intents.all())

async def setup_hook():
	await bot.load_extension(f'cogs.test')

token = os.environ['TOKEN']
bot.run(token)

i still can't figure out.

You have to replace the default setup hook. You are defining a new hook but never replacing the old one. You can do this using something like this:

import discord, os
from discord.ext import commands
from keep_alive import keep_alive

bot = discord.ext.commands.Bot(command_prefix="&", intents=discord.Intents.all())

async def setup_hook():
	await bot.load_extension(f'cogs.test')

bot.setup_hook = setup_hook

token = os.environ['TOKEN']
bot.run(token)

[izxxr]

setup_hook is a method of Bot class that you have to override. You have to subclass Bot and override that method.

class Bot(commands.Bot):
  async def setup_hook(self):
      ...

bot = Bot(...)

If you don't want to subclass the Bot class, you can use an alternative method for async setup by using asyncio.run() with your own async function used as entry point. An example is given in the section I mentioned above.
