Node JS Express-更新单个文档
[英]Node JS express - updating a single document
问题描述
我不知道为什么我的文件没有更新。
我获取任何记录，并将其装入http：// localhost：3000 / update2？buyerID = 2299的表单中 。 但是，当我更改字段并单击提交时，当我重定向到列出所有文档的路由时，该字段不会更新。 它和以前一样。
谁能看到我在哪里出问题了？
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});
}
})
}
});
}
});

您是否尝试过findOne然后用修改markModified对象字段的？
function async(cb) {
WishList.findOne({id: id}, function(err, doc) {
if (err) throw err;
doc.buyerID = req.body.buyerID;
doc.name = {
f: req.body.f,
s: req.body.s
};
doc.address = {
HouseNum: req.body.HouseNum,
streetName:req.body.streetName,
town:req.body.town,
postCode: req.body.postCode
};
doc.deliveryInfo = [{delivId: req.body.delivId,
serviceName: req.body.serviceName,
postTime: req.body.postTime,
delivCost: req.body.delivCost,
pickUp: req.body.pickUp}];
doc.gender = req.body.gender,
doc.student = req.body.student,
doc.pName = req.body.pName,
doc.purchaseDate = req.body.purchaseDate,
doc.price = req.body.price,
doc.sName = req.body.sName
doc.markModified('name');
doc.markModified('address');
doc.markModified('deliveryInfo');
doc.save(cb);
};
}
