node.js - Express js中通过id删除mongodb文档

Question

我正在为此抓狂...尝试通过 id 删除文档:

router.delete('/api/menu/delete/:id', function (req, res) {
  var id = req.params.id;
  db.get().collection('menu', function (err, col) {
   col.deleteOne({_id: new mongodb.ObjectID(id)});
  });
  res.json({ success: id })
});

总是得到:

Cannot read property deleteOne of undefined

当尝试查找记录时，它按预期工作。

明白了。首先我需要 mongodb

mongo = require('mongodb')

然后:

router.delete('/api/menu/delete/:id', function (req, res) {
  var id = req.params.id;
  var collection = db.get().collection('menu');

  collection.deleteOne({ _id: new mongo.ObjectId(id) }, function (err, results) {
  });

  res.json({ success: id })
});
