How can I know who triggers on_member_update?

[riccardolunardi]

In my server everyone can change other people's nicknames.
on_member_update(before, after) give the ability to know how the user changed after the update, but how can I know who made the update?

I tried looking on the intenet but didn't find anything helpful :(

You can iterate through your server's audit log

Basically, since before and after are Member objects, you can get the guild from them:

@commands.Cog.listener()
async def on_member_update(self, before, after):
  async for entry in after.guild.audit_logs(limit=10):
      print('{0.user} did {0.action} to {0.target}'.format(entry))

I don't know if this is the best way to do that, but it works. Another way is to get the guild from a specific ID:

@commands.Cog.listener()
async def on_member_update(self, before, after):
  guild = self.bot.get_guild(123456789)
  async for entry in guild.audit_logs(limit=10):
      print('{0.user} did {0.action} to {0.target}'.format(entry))

Thanks, that's what I thought I should do, too. I wondered if there was another way, but this look like the one to go.
