Discord music bot not reading the command - python-3.x

Question

So, I'm trying to make a discord music bot and I keep getting this one error whenever I use the play command I think its not loading the cog or has something to do with that. this is my main function
and this is my command inside my music_player classthe error that I'm getting once I run the code
import discord
from discord.ext import commands
import os
from youtube_dl import YoutubeDL
intents = discord.Intents.default()
intents.message_content = True
bot = commands.Bot(
command_prefix=commands.when_mentioned_or("!"),
description='Relatively simple music bot example',
intents=intents,
)
#bot.event
async def on_ready():
print(f'Logged in as {bot.user} (ID: {bot.user.id})')
print('------')
bot.add_cog("cogs.music_player")

# If user is not in the voice channel
voice_channel = ctx.author.voice_channel
if voice_channel is None:
await ctx.send("You're not in a voice channel you dummy")

await ctx.send("Incorrect format of song could not play")
else:
await ctx.send("Song added")
self.musicque.append([song, voice_channel])
if self.isplaying == False:
await self.play_song(ctx)
I was expecting the program to play a song or atleast join thet voice channel but apparently it says the command is not found I've tried changing stuff with the cog but it didn't help so I'm fully lost at what I'm doing wrong.

Answer 1

The add_cog method doesn't work that way; it takes a cog class as an argument, not the path to the cog file. That's the load_extension's job. The load_extension will go to the given path and call the setup function inside the file, and you have to add the cog inside that setup function. For example:
 
cogs/cog_file.py
class ACogClass(discord.ext.commands.Cog):
    ...
 
async def setup(bot: discord.ext.commands.Bot): # as of discord.py 2, the "setup" function needs to be an async function
    bot.add_cog(ACogClass(bot))
 
main.py
bot = discord.ext.commands.Bot(...)
 
async def setup_hook():
    await bot.load_extension("cogs.cog_file") # as of discord.py 2, the "load_extension" method is now an async function
 
bot.setup_hook = setup_hook # set the bot's default "setup_hook" to our custom "setup_hook"
