Loop Through Discord Message History In Channel And Delete-CodePudding

I am trying to loop through message history of a particular Discord channel and delete all previous messages before sending new messages to the channel. I can't seem to figure this out and have searched EVERYWHERE to find a solution. My code below:

import discord
from discord.ext import tasks, commands
import asyncio

client = discord.Client()

@client.event
async def on_ready():
  print('We have logged in as {0.user}'.format(client))

async def my_background_task():
  channel = client.get_channel(999999999999999)
  history = await channel.history().flatten()
  await channel.delete_messages(history)
  
  # Loop and send messages to channel
  while not client.is_closed():
    await channel.send('Test')
        schedule.every(5).seconds.do(my_background_task)
    
# Loop event
@client.event
async def on_ready():
    print('Running...')
    client.loop.create_task(my_background_task())

When I go to run my code, I get the following error:

repl process died unexpectedly: signal: killed

CodePudding user response：

You can try using the channel.purge() methode instead. It Works fine for me. The only Problem is that it will be a bit laggy if there are too many messages in the channel.

import discord
from discord.ext import tasks, commands
import asyncio

client = discord.Client()

@client.event
async def on_ready():
  print('We have logged in as {0.user}'.format(client))

#deletes all messages in one particular channel
async def deleteAllMessages(deleted, channel):
    purge = len(await channel.purge(limit=100))
    if purge < 100:
        print(f"process finished\n{deleted purge} messages were deleted.")
        return
    else: 
        await deleteAllMessages(deleted 100, channel)
        return

async def my_background_task():
    channel = client.get_channel(999999999999999)
    await deleteAllMessages(0, channel)
  
    #Loop and send messages to channel
    if not client.is_closed():
        await channel.send('Test')
            schedule.every(5).seconds.do(my_background_task)
    
# Loop event
@client.event
async def on_ready():
    print('Running...')
    client.loop.create_task(my_background_task())
