How to edit a message in discord.py

Question

I would like to have my bot edit a message if it detects a keyword, i'm not sure how to edit the message though.

I've looked through the documentation but can't seem to figure it out. I'm using discord.py with python 3.6.

This is the code:

@bot.event
async def on_message(message):
    if 'test' in message.content:
        await edit(message, "testtest")

This is the error:

  File "testthing.py", line 67, in on_message
    await edit(message, "test")
 NameError: name 'edit' is not defined

I would like the bot to edit a message to "testtest" if the message contains the word test, but i just get an error.

Solution 1

You can use the Message.edit coroutine. The arguments must be passed as keyword arguments content, embed, or delete_after. You may only edit messages that you have sent.

await message.edit(content="newcontent")

Solution 2

Here's a solution that worked for me.

@client.command()
async def test(ctx):
  message = await ctx.send("hello")
  await asyncio.sleep(1)
  await message.edit(content="newcontent")

I tried it, but i just get this error: raise Forbidden(r, data) discord.errors.Forbidden: FORBIDDEN (status code: 403): Cannot edit a message authored by another user

Although I have admin permissions on the bot.

@nijwons Actually, the docs for manage_messages lead me to believe that you cannot edit another users message.

Oh, is that so? Is it the same for nicknames as i get the same error with that.

@nijwons There is a permission for that: manage_nicknames. Make sure your bot has that, and check if it is a role hierarchy issue. Your bot may not be able to edit users whose highest role is higher than the highest role of the bot.

Should we store the message object which is created from await self.channel.send(msg) ?
