我無法確定我的文檔沒有更新。Node JS express - 更新單個文檔
我獲取任何記錄並將其加載到與http://localhost:3000/update2?buyerID=2299的形式。但是當我更改一個字段並單擊提交時，該字段不會更新時，我重定向到列出所有文檔的路由。它和以前一樣。
任何人都可以看到我會出錯嗎？

得到
router.get('/update2', function(req, res) {
var buyerID = req.query.buyerID;
if (!buyerID || !parseInt(buyerID)) {
res.render('error', {message: "You need to enter a buyerID to update a specific order", error:{status:"", stack: ""}});
} else {
mongoClient.connect(url, function (err, db) {
if (err) {
res.render('error', {message: "Failed to connect to MongoDB",error:{status:"", stack: ""}});
} else {
var WishList = db.collection('orders');
WishList.findOne({"buyerID": parseInt(buyerID)}, function(err, result) {
if (err || !result || result.length == 0) {
res.render('error', {message: "Failed to find order",error:{status:"", stack: ""}});
} else {
console.log("get results", result)
res.render('updateOrder2', {qs: result});
}
})
}
});
}
});
後
router.post('/update2', function(req, res) {
if (!buyerID || !parseInt(buyerID)) {
res.render('error', {message: "Failed to update order make sure the ID is current", error:{status:"", stack: ""}});
} else {
mongoClient.connect(url, function (err, db) {
if (err) {
res.render('error', {message: "Failed to connect to MongoDB", error:{status:"", stack: ""}});
} else {
var WishList = db.collection('orders');
var buyerID = req.query.buyerID;
var u2Order = {
buyerID: req.body.buyerID,
name: {
f: req.body.f,
s: req.body.s
},
address: {
HouseNum: req.body.HouseNum,
streetName:req.body.streetName,
town:req.body.town,
postCode: req.body.postCode
},
deliveryInfo: [{delivId: req.body.delivId,
serviceName: req.body.serviceName,
postTime: req.body.postTime,
delivCost: req.body.delivCost,
pickUp: req.body.pickUp}],
gender: req.body.gender,
student: req.body.student,
pName: req.body.pName,
purchaseDate: req.body.purchaseDate,
price: req.body.price,
sName: req.body.sName
};
console.log("Updating..", u2Order)
WishList.updateOne({"buyerID": parseInt(buyerID)}, {$set: u2Order}, function (err, result){
if (err) {
console.log("Cannot update", err)
} else {
console.log("Updated..", order)
res.redirect("/orders")
}
})
}
});
}
});

您使用的是Mongoose還是任何類型的ORM？有助於瞭解我們正在處理的事情。 –
即時通訊使用express和MongoDB。不是貓鼬 –
你能看到這個問題嗎？ –
