Update Topic slug

What's the right way to update a topic slug?
I am trying to "parse and convert" all topic titles, but I would like the slugs to match the changes.

basically something like this

   var parse = function() { /* some custom parser function ...*/  };
   var slugify = utils.slugify; // the core NodeBB utils.slugify

   var newTitle = parse(oldTitle);

    db.setObjectField('topic:' + topic.tid, 'title', newTitle, function(err) {
        if (err) return cb(err);
        db.setObjectField('topic:' + topic.tid, 'slug', slugify(newTitle), cb);
    });

This results in some weird behavior, the topic generated URLs no longer include the tid so

/topic/1/my-topic-title changed to /topic/my-topic-title

I am assuming there is another field that needs to be updated, but can't find it

relevant issue: https://github.com/akhoury/nodebb-plugin-import/issues/45, last few comments are the most relevant.

The topic slugs include the topic id so the value stored in the database for this topic is 2647/update-topic-slug for example.

Your code should be

db.setObjectField('topic:' + topic.tid, 'title', newTitle, function(err) {
    if (err) return cb(err);
    db.setObjectField('topic:' + topic.tid, 'slug', topic.tid + '/' + slugify(newTitle), cb);
});
