Python - deleting a DM in Discord with on_raw_reaction_add

I'm trying to have my Discord bot delete messages when reacting with an emoji. I have some code for it, which works in a Discord server, but it does not work in DMs

This is my code

self = discord.Bot()
@self.event
async def on_raw_reaction_add(ctx):
    if ctx.emoji.name == '❌':
        message = await self.get_channel(ctx.channel_id).fetch_message(ctx.message_id)
        await message.delete()

This is the error

AttributeError: 'NoneType' object has no attribute 'fetch_message'

Since I figure DMs apparently don't have "channels", I've tried getting just the specific message ID with

message = ctx.message_id

but I can't find any way to delete messages by ID that works with on_raw_reaction_add

All the similar questions I've found here about deleting bot DMs aren't working with on_raw_reaction_add. Any help is appreciated, thank you.

Solution

  • You need to use user.fetch_message to fetch a message in a DMChannel. So you could check if the channel exists, and if it does not, you can get the user instead.

    Example:

    @self.event
async def on_raw_reaction_add(ctx):
    if ctx.emoji.name == "❌":
        channel = self.get_channel(ctx.channel_id)
        if not channel:
            channel = await self.fetch_user(ctx.user_id)

        message = await channel.fetch_message(ctx.message_id)

        await message.delete()

    Please keep in mind that you will not be able to delete the messages of the other person, only your own bot's messages. This is a discord limitation.
