从Express，Node.js应用程序中删除MongoDB文档

Question

My index.jade file(my button which the users clicks to delete the document) is:

a(href="/delete/#{booking.id}") Delete

So far in my index.js file is:

router.get('/delete/:id', function (req, res) {
  Booking.findOneAndDelete({ id: req.params.id }).remove().exec();
});

I also, tried:

router.get('/delete/:id', function (req, res) {
  Booking.findById(id, function (err, doc) {
  if (err) {
    message.type = 'Error!';
  }
  doc.remove(callback); //Removes the document
  });

Neither are working, I just get the url with the ID:

localhost:3000/delete/54d49430b08883dc2fc8bb0d

You need to execute before you can remove, you should also be performing a delete request and not a .get(). Try this:

router.delete('/delete/:id', function (req, res) {
    Booking.findById(req.params.id)
        .exec(function(err, doc) {
            if (err || !doc) {
                res.statusCode = 404;
                res.send({});
            } else {
                doc.remove(function(err) {
                    if (err) {
                        res.statusCode = 403;
                        res.send(err);
                    } else {
                        res.send({});
                    }
                });
            }
        });
});
