How to update populated fields?

Question

Mongoose

Is it possible to change the data in a related document?
Something like this:

User.findById(id).populate('profile').exec(function(err, user) {
  user.profile.description = newDescription;
  user.save();
});

Answer 1

Maybe so?

User.findById(id).populate('profile').exec(function(err, user) {
  Profile.findOneAndUpdate({ _id: user.profile }, { description: newDescription });
  user.save();
});
