python - How to get a DMChannel object? - discord.py

Question

I want the bot to check what is the channel with the new emoji and then do different things, depends on what the new emoji is. It works properly until the emoji is on a private channel, which makes the bot.get_channel(payload.channel_id) return None.

I had the same problem with a user or member id. The payload.member returns None, but bot.get_user(payload.user_id) returns the member object. So, is there something like this but with channels? What is used to get the DMChannel object?

@bot.event
async def on_raw_reaction_add(payload):
print(bot.get_channel(payload.channel_id), payload.channel_id) # This line will be deleted, it is used for showing the problem.
if payload.user_id != None:
    channel = bot.get_channel(payload.channel_id)
    msg = await channel.fetch_message(payload.message_id)
    emoji = payload.emoji
    author = payload.member
    if emoji.is_custom_emoji():
        emoji_count = discord.utils.get(msg.reactions, emoji=emoji).count
    else:
        emoji_count = discord.utils.get(msg.reactions, emoji = emoji.name).count
    if payload.channel_id == channel_i:
        if emoji_count > 1:
           ...

The output if the reaction is in a DM channel, the error occurs because the channel is NoneType, which is caused by the previous line.

Answer 1

Is there a reason you need to use on_raw_reaction_add rather than on_reaction_add? In 99% of cases the latter does the same as the former. That being said its parameters are reaction, user [documentation] which are much more easily parseable, because they are discord.py objects.

Rather than retrieving the channel by bot.get_channel you can then just can just call

channel = reaction.channel.message

Full example:

@bot.event
async def on_reaction_add(reaction, user):
    channel = reaction.message.channel
