Integrate a delete option in my discord bot

Question

I am creating a bot for my discord and I have been trying for 3 days to integrate the delete option and I encounter the following problem:

in delete
    messages = await ctx.channel.history(limit=number_of_messages + 1).flatten()
AttributeError: 'async_generator' object has no attribute 'flatten'


raise CommandInvokeError(exc) from exc
discord.ext.commands.errors.CommandInvokeError: Command raised an exception: AttributeError: 'async_generator' object has no attribute 'flatten'

Code:

@bot.command(name='del')
async def delete(ctx: commands.Context, number_of_messages: int):
    messages = await ctx.channel.history(limit=number_of_messages + 1).flatten()

    for each_message in messages:
        await each_message.delete()

python version : 3.10.11

Answer 1

In discord.py 2.0 the .flatten() method was removed since the introduction of async list comprehensions.

@bot.command(name='del')
async def delete(ctx: commands.Context, number_of_messages: int):
    messages = [message async for message in ctx.channel.history(number_of_messages + 1)]

    for each_message in messages:
        await each_message.delete()

This is a bad solution, though. Use the channel.purge() method since it bulk deletes messages:

@bot.command(name='del')
async def delete(ctx: commands.Context, number_of_messages: int):
    await ctx.channel.purge(limit=number_of_messages + 1)
