AttributeError: 'CogLoader' object has no attribute '_BotBase__extensions' - discord.py

Question

As a part of learning OOP, I'm trying to create a class that will handle the loading and unloading cogs. However I'm getting the following error
Traceback (most recent call last):
File "c:\Users\mirza\Desktop\Work\Working Directory\Project\Bots\2B\bot.py", line 50, in <module>
main()
File "c:\Users\mirza\Desktop\Work\Working Directory\Project\Bots\2B\bot.py", line 43, in main
bot = CustomBotClient()
File "c:\Users\mirza\Desktop\Work\Working Directory\Project\Bots\2B\bot.py", line 21, in __init__
raise e
File "c:\Users\mirza\Desktop\Work\Working Directory\Project\Bots\2B\bot.py", line 18, in __init__
self.load_extension(f"cogs.{filename[:-3]}")
File "C:\Users\mirza\AppData\Local\Programs\Python\Python39\lib\site-packages\discord\ext\commands\bot.py", line 671, in load_extension
if name in self.__extensions:
AttributeError: 'CustomBotClient' object has no attribute '_BotBase__extensions'
This the code from bot.py that is giving me the error
import discord
from discord.ext import commands
import os
from dotenv import load_dotenv
class CogLoader(commands.Bot):
def __init__(self):
for filename in os.listdir('./cogs'):
if filename.endswith(".py"):
try:
self.load_extension(f"cogs.{filename[:-3]}")
except Exception as e:
print(f"cogs.{filename[:-3]} cannot be loaded")
raise e
#commands.command()
async def load(self, ctx, extension):
self.load_extension(f"cogs.{extension}")
#commands.command()
async def unload(self, ctx, extension):
self.unload_extension(f"cogs.{extension}")
#commands.command()
async def reload(self, ctx, extension):
self.unload_extension(f"cogs.{extension}")
self.load_extension(f"cogs.{extension}")
class CustomBotClient(CogLoader):
async def on_ready(self):
print(f"Bot {self.user} is connected to Discord and ready to roll!")
def main():
bot = CustomBotClient()
load_dotenv()
bot.run(os.getenv("TOKEN"))
if __name__ == "__main__":
main()
This is the cog that I'm trying to load
from discord.ext import commands
class Greetings(commands.Cog):
def __init__(self, bot):
self.bot = bot
#commands.command(name="GreetME")
async def greet_me(self, ctx):
await ctx.send("Hello! {author.user}")
def setup(bot):
bot.add_cog(Greetings(bot))
I'm following a youtube tutorial but he didnot used a class for this. So, I'm a loss here. Any help would be appreciated.

Answer 1

You need to initialize the commands.Bot in your CogLoader.__init__
This can be accomplished through the following code:
class CogLoader(commands.Bot):
def __init__(self, command_prefix, **options):
super().__init__(command_prefix, **options)
for filename in os.listdir('./cogs'):
if filename.endswith(".py"):
try:
self.load_extension(f"cogs.{filename[:-3]}")
except Exception as e:
print(f"cogs.{filename[:-3]} cannot be loaded")
raise e
and
def main():
bot = CustomBotClient(command_prefix="!")
This way, commands.Bot and BotBase, their attributes and their methods are loaded.
