Question

我是node / express / mongo的新手。我正在努力学习但是一个错误正在完成我的一天。不知道为什么。谷歌搜索它仍然找不到任何适当的解决方案。以下是来自pastebin的代码，您可以在其中找到我的代码。

我发生了以下错误，虽然我使用objectID for mongo从url获取id参数。你能帮帮我吗...

Error: 
Error: Argument passed in must be a single String of 12 bytes or a string of 24 hex characters

由于我没有得到任何答案，我设法解决了这个问题。似乎我的参数没有正确设置错误来了，所以我更新了我的路线，如下所示：

// update quote
app.post( '/update/edits', ( req, res ) => {
    db.collection('quote').update (
        { _id: ObjectId(req.body.quoteID) },
        { $set: {
            name: req.body.name,
            quote: req.body.quote
            }
        }, function (err, result) {
            if (err) {
                req.flash('error', err);
            } else {
                req.flash('success', 'Quote updated successfully');
            }
            res.redirect('/');
     });
});

顺便说一下，如果它对任何其他人有帮助，你可以在我的github中检查完成的CRUD系统。

无法使用express + mongo + node更新基于id的数据
