Redirect to new Mongo Saved ID after Express POST?

In my POST request, I'm saving a new document into my mongo database. After the database is saved, can I do a res.redirect to that exact document ID?? I'm unsure of how to do this. I can't find any tutorials, documentation, or stackoverflow questions that seem to answer exactly what I'm looking for.

Can I do something like this? Where the :id is the Id of the document I just saved in mongoose/mongo?

newItem.save().then(res.redirect('/results/:id');

I expect the user to submit a post request. I'm saving the information into a mongo document through mongoose. Then after saving it I'd like to redirect to a new URL with the ID of the saved item on that page.

Of course you can.

The save() method can accept a callback so you can get the _id field of the saved document.

One way of do it would be:

newItem.save((err, itemSaved) => {
    if(err) {
        next(err);
    }
    const itemId = itemSaved._id;
    res.redirect('/results/' + itemId);
});

Hopefully, this will solve your problem.

P.S.

There's no need to use a colon on redirect's path. Beware with that, 'cause using it will give you a Cast Error.
