I'm using mongoose and returning documents from a collection to be displayed using datatables. I'm having some issues though. The client-side code is
var table = $('#dataTables-example').DataTable( {
"bProcessing" : true,
"bServerSide" : true,
"ajax" : {
"url" : "/mongo/get/datatable",
"dataSrc": ""
},
"columnDefs": [
{
"data": null,
"defaultContent": "<button id='removeProduct'>Remove</button>",
"targets": -1
}
],
"aoColumns" : [
{ "mData" : "name" },
{ "mData" : "price" },
{ "mData" : "category" },
{ "mData" : "description" },
{ "mData" : "image" },
{ "mData" : "promoted" },
{ "mData" : null}
]
});
Then this handled on the server-side using the following
db.once('open', function callback ()
{
debug('Connection has successfully opened');
productSchema = mongoose.Schema({
name: String,
price: String,
category: String,
description: String,
image: String,
promoted: Boolean
});
Product = mongoose.model('Product', productSchema, 'products');
});
exports.getDataForDataTable = function (request, response) {
Product.dataTable(request.query, function (err, data) {
debug(data);
response.send(data);
});
};
If I use the above code the datatable fails to display the documents, claiming no matching records found BUT it does correctly display the number of docs Showing 1 to 2 of 2 entries. If I change the server side code to response with data.data instead of data, the documents are correctly populated in the table BUT the number of records is no longer found, instead saying Showing 0 to 0 of 0 entries (filtered from NaN total entries)
exports.getDataForDataTable = function (request, response) {
Product.dataTable(request.query, function (err, data) {
debug(data);
response.send(data.data);
});
The actual data being returned when querying mongo is
{ draw: '1', recordsTotal: 2, recordsFiltered: 2, data: [ { _id: 5515274643e0bf403be58fd1, name: 'camera', price: '2500', category: 'electronics', description: 'lovely', image: 'some image', promoted: true }, { _id: 551541c2e710d65547c6db15, name: 'computer', price: '10000', category: 'electronics', description: 'nice', image: 'iamge', promoted: true } ] }
The third parameter in mongoose.model sets the collection name which is pluralized and lowercased automatically so it has no effect in this case.
Assuming your Product variable has been declared early on and global, try this:
products = mongoose.model('products', productSchema);
Product = require('mongoose').model('products');
Did you try to remove the dataSrc field in the DataTable configuration:
"ajax" : {
"url" : "/mongo/get/datatable",
},

I have this record
{
"_id" : ObjectId("5dfdff479ad032cbbc673507"),
"selection" : [
{
"highlights" : "test",
"comment" : "CHANGE THIS",
"el" : "body:nth-child(2)>div:nth-child(2)#root>div.App>p:nth-child(1)"
},
{
"highlights" : "Barrett’s lyrical prose opens with a clever and tender solution",
"comment" : "",
"el" : "body:nth-child(2)>div:nth-child(2)#root>div.App>p:nth-child(2)"
}
],
"category" : [],
"status" : "",
"url" : "http://localhost:3000/theone",
"title" : "React App test",
"__v" : 4
}
And I want to update the comment. I have tried to use update and findOneAndUpdate and nothing is working. Here is my attempt
WebHighlight.findOneAndUpdate(
{
_id: req.params.highlight,
"selection.highlights": "test"
},
{ "selection.$.comment": "yourValue" }
);
That req.params.highlight is the id (I even hardcoded it)
I also tried this
WebHighlight.findById(req.params.highlight, (err, book) => {
var test = [...book.selection];
test[0].comment = "somethibf"
book.save();
res.json(book);
});
And nothing is working.
This is the model
const webhighlightsModel = new Schema({
selection: { type: Array, default: "" },
category: { type: Array, default: [] },
title: { type: String },
url: { type: String },
status: { type: String, default: "" }
});
Actually your code seems to work, but findOneAndUpdate returns the old document if you don't give {new: true} option.
I think for this reason, you think the update wasn't successfull, but if you check your collection, you will see the update.
WebHighlight.findOneAndUpdate(
{
_id: req.params.highlight,
"selection.highlights": "test"
},
{ "selection.$.comment": "yourValue" },
{ new: true }
)
.then(doc => res.send(doc))
.catch(err => res.status(500).send(err));
Also I think it would be better if selection had a sub schema like this:
const mongoose = require("mongoose");
const schema = new mongoose.Schema({
selection: [
new mongoose.Schema({
highlights: String,
comment: String,
el: String
})
],
category: { type: Array, default: [] },
title: { type: String },
url: { type: String },
status: { type: String, default: "" }
});
module.exports = mongoose.model("WebHighlight", schema);
So with this every selection would an _id field, and it would be better to update with this _id.
You should use the $set operator to update existing values:
WebHighlight.findOneAndUpdate(
{
_id: req.params.highlight,
"selection.highlights": "test"
},
{ '$set': { "selection.$.comment": "yourValue" } }
);
I can't get mongoose to show subdocument when running find() while it displays perfectly well in mongodb shell.
Subdocument should be embedded based on my schema, not objectId referenced, so I shouldn't be running any black magic voodoo to get my data to show up.
const UserSchema = new mongoose.Schema({
username: String;
xp: Number;
//etc.
});
const RoomSchema = new mongoose.Schema({
timestamp: { type: Date, default: Date.now },
status: { type: String, enum: ["pending", "ongoing", "completed"]},
players: {
type: [{
points: { type: Number, default: 0 },
position: String,
user: UserSchema
}],
maxlength:2
}
});
After adding a new room with:
let room = new Room(coreObj);
room.players.push({
points: 0,
position: 'blue',
user: userObj //where userObj is a result of running findById on User model
});
It displays nicely in mongo shell, when running db.rooms.find({}).pretty() I can see that full document has been added. However, when running on mongoose model:
Room.find({}).exec((err,rooms)=>{
console.log(rooms[0].toJSON());
});
I don't see user subdocument, moreover I cannot see user field entirely! What seems to be the problem?
logged json from mongoose model:
{
"status": "pending",
"_id": "5cf5a25c050db208641a2076",
"timestamp": "2019-06-03T22:42:36.946Z",
"players": [
{
"points": 0,
"_id": "5cf5a25c050db208641a2077",
"position": "blue"
}
],
"__v": 0
}
json from mongo shell:
{
"_id" : ObjectId("5cf5a25c050db208641a2076"),
"status" : "pending",
"timestamp" : ISODate("2019-06-03T22:42:36.946Z"),
"players" : [
{
"points" : 0,
"_id" : ObjectId("5cf5a25c050db208641a2077"),
"position" : "blue",
"user" : {
"xp" : 0,
"_id" : ObjectId("5cf2da91a45db837b8061270"),
"username" : "bogdan_zvonko",
"__v" : 0
}
}
],
"__v" : 0
}
Keeping best practice in mind, I think it would be more appropriate to reference the UserSchema in the RoomSchema. Something like:
...
user: {
type: Schema.Types.ObjectId,
ref: 'UserSchema'
}
Then you would store the user._id in that field.
This way, if the user is modified, your RoomSchema is always referencing the correct information. You could then get the user using Mongoose's populate
I'm not entirely sure why you can't see the sub-sub-document, but this code example printed it correctly for me. Example was originally posted in https://mongoosejs.com/docs/subdocs.html but modified slightly to contain sub-sub-document so it looks similar to your code:
var grandChildSchema = new mongoose.Schema({ name: 'string' });
var childSchema = new mongoose.Schema({ name: 'string', grandChild: grandChildSchema });
var parentSchema = new mongoose.Schema({ children: [childSchema] });
var Parent = mongoose.model('Parent', parentSchema);
var parent = new Parent({
children: [
{ name: 'Matt', grandChild: {name: 'Matt Jr'} },
{ name: 'Sarah', grandChild: {name: 'Sarah Jr'} }
]
})
parent.save(function() {
Parent.find().exec(function(err, res) {
console.log(JSON.stringify(res[0]))
mongoose.connection.close()
})
});
Executing this code resulted in:
{
"_id": "5cf7096408b1f54151ef907c",
"children": [
{
"_id": "5cf7096408b1f54151ef907f",
"name": "Matt",
"grandChild": {
"_id": "5cf7096408b1f54151ef9080",
"name": "Matt Jr"
}
},
{
"_id": "5cf7096408b1f54151ef907d",
"name": "Sarah",
"grandChild": {
"_id": "5cf7096408b1f54151ef907e",
"name": "Sarah Jr"
}
}
],
"__v": 0
}
This was tested using Mongoose 5.5.12.
Note that I was using JSON.stringify() to print the document instead of using Mongoose's toJSON().
I just met a very similar problem, i think i got it.
the whole point is in model which you use:
const RoomSchema = new mongoose.Schema({
...
players: {
type: [{
...
user: UserSchema
...
but then you make
room.players.push({
points: 0,
position: 'blue',
user: userObj //where userObj is a result of running findById on User model
});
so you are missing the "type" subfield, so your doc is not compliant with your RoomSchema and mongoose do not show the parts which does not fit schema.
Update: I am looking for an answer that works within mongodb projection: https://docs.mongodb.com/manual/reference/method/db.collection.findOne/#definition
I am trying to filter a query on a subdocument using projection so that it only returns a specific array. But when filtering the result also includes an array of another subdocument. When I don't filter it only returns the found document.
I tried different filtering options including and excluding positional elements, but can't get the desired return.

There are two stations under one user:

}
Projection options tried
const options = {
'stations.measures': 1
}
const options = {
'stations.$.measures': 1
}
const options = {
'stations.$': 1,
'stations.$.measures': 1
}
const options = {
'stations.$': 1,
'stations.measures': 1
}
What am I doing wrong?
try using these querying params only and after that you will get a user with a requested station..
var user = {
apiKey: req.user.apiKey
}
const query = {
apiKey: user.apiKey,
'stations.stationName': req.params.stationName
}
then do this
User.findOne(query, options)
.exec()
.then(stations => {
for(let station of stations){
if(station.measures[1]){ // here it is the index
res.status(200).send(stations);
}
}
})
.catch(err => {
console.log(err);
res.status(400).send(err);
})
actually in mongoose you cannot query sub-sub documents to you will have to you this approach.. You can only query sub docs only like you have done
Lemme take time to explain what is happening from start to finish.
Preamble:
A user a follows 10 other people. When user A logs in, an X number of posts from each of the 10 people are pulled into view.
I do not know if it is the right thing to do, and will appreciate a better way of doing it. However, I wanna give it a try, and it ain't working.
Follow Model:
let mongoose = require('mongoose');
let Schema = mongoose.Schema;
let FollowSchema = new Schema({
user: {
type: Schema.Types.ObjectId,
ref: 'User'
},
followers: [{
type: Schema.Types.ObjectId,
ref: 'Card'
}],
following: [{
type: Schema.Types.ObjectId,
ref: 'Card'
}]
});
module.exports = mongoose.model('Follow', FollowSchema);
Card Model
let mongoose = require('mongoose');
let Schema = mongoose.Schema;
let CardSchema = new Schema({
title: String,
content: String,
createdById: {
type: Schema.Types.ObjectId,
ref: 'User'
},
createdBy: {
type: String
}
});
module.exports = mongoose.model('Card', CardSchema);
Follow logic
When user A follows user B, do two things:
Push the user_id of B to user A document on field 'following' (A is following B)
Push user_id of A to user B document on field 'followers' (B is followed by A)
router.post('/follow', utils.loginRequired, function(req, res) {
const user_id = req.user._id;
const follow = req.body.follow_id;
let bulk = Follow.collection.initializeUnorderedBulkOp();
bulk.find({ 'user': Types.ObjectId(user_id) }).upsert().updateOne({
$addToSet: {
following: Types.ObjectId(follow)
}
});
bulk.find({ 'user': Types.ObjectId(follow) }).upsert().updateOne({
$addToSet: {
followers: Types.ObjectId(user_id)
}
})
bulk.execute(function(err, doc) {
if (err) {
return res.json({
'state': false,
'msg': err
})
}
res.json({
'state': true,
'msg': 'Followed'
})
})
})

With the above database results, this is my query:
Query
router.get('/follow/list', utils.loginRequired, function(req, res) {
const user_id = req.user._id;
Follow.findOne({ 'user': Types.ObjectId(user_id) })
.populate('following')
.exec(function(err, doc) {
if (err) {
return res.json({
'state': false,
'msg': err
})
};
console.log(doc.username);
res.json({
'state': true,
'msg': 'Follow list',
'doc': doc
})
})
});
With the above query, from my little understanding of Mongoose populate, I expect to get cards from each of the Users in the following array.
My understanding and expectations might be wrong, however with such an endgoal, is this populate approach okay? Or am I trying to solve an aggregation task with population?
UPDATE:
Thanks for the answer. Getting quite close, but still, the followingCards array contains no result. Here's the contents of my current Follow model:

With the Populate Virtual example from yours (#Veeram), here's the response I get:
{"state":true,"msg":"Follow list","doc":{"_id":"59f24c0555ee5a5897e1b23d","user":"59f24bda1d048d1edad4bda8","following":["59f24b3a55ee5a5897e1b1ec","59f24bda55ee5a5897e1b22c"],"followers":[],"id":"59f24c0555ee5a5897e1b23d","followingCards":[]}}
The followingCards array is empty.
Using the $lookup query on the other hand simply returns []
I'm likely missing something?
You can use either virtual populate or $lookup operator in aggregation pipeline.
Using Virtual Populate
FollowSchema.virtual('followingCards', {
ref: 'Card',
localField: 'following',
foreignField: 'createdById'
});
Follow.findOne({
'user': Types.ObjectId(user_id) })
.populate('followingCards')
.exec(function(err, doc) {
console.log(JSON.stringify(doc));
});
Using $lookup aggregation
Follow.aggregate([
{
"$match": {
"user": Types.ObjectId(user_id)
}
},
{
"$lookup": {
"from": "cards",
"localField": "following",
"foreignField": "createdById",
"as": "followingCards"
}
}
]).exec(function (err, doc) {
console.log(JSON.stringify(doc));
})
var mongoose = require('mongoose'), Schema = mongoose.Schema
var eventSchema = Schema({
title : String,
location : String,
startDate : Date,
endDate : Date
});
var personSchema = Schema({
firstname: String,
lastname: String,
email: String,
dob: Date,
city: String,
eventsAttended: [{ type: Schema.Types.ObjectId, ref: 'Event' }]
});
var Event = mongoose.model('Event', eventSchema);
var Person = mongoose.model('Person', personSchema);
To show how populate is used, first create a person object,
aaron = new Person({firstname: 'Aaron'}) and an event object,
event1 = new Event({title: 'Hackathon', location: 'foo'}):
aaron.eventsAttended.push(event1);
aaron.save(callback);
Then, when you make your query, you can populate references like this:
Person
.findOne({ firstname: 'Aaron' })
.populate('eventsAttended') .exec(function(err, person) {
if (err) return handleError(err);
console.log(person);
});
// only works if we pushed refs to person.eventsAttended
note: change Activity.find to Card.find
const { ObjectID } = require("mongodb");
// import Follow and Activity(Card) schema
const userId = req.tokenData.userId; // edit this too...
Follow.aggregate([
{
$match: {
user: ObjectID(userId)
}
}
])
.then(data => {
// console.log(data)
var dataUsers = data[0].following.map(function(item) {
return item._id;
});
// console.log(dataUsers)
Activity.find(
{ createdById: { $in: dataUsers } },
{
_id: 1,
title: 1,
content: 1,
createdBy: 1,
creatorAvatar: 1,
activityType: 1,
createdAt: 1
}
)
// .sort({createdAt:-1)
.then(posts => res.send({ posts }));
});
I have a Kendo UI Grid that is calling a rest service. It works fine, as long as I do not try to use any params.
I know the the rest service is correct, as I can call it from a browser, and get correct results [depending on the param I send]. Also, when I look the server log I see that it is calling the rest service with no params.
My code is below:
document).ready( function() {
var crudServiceBaseUrl = "rsPC.xsp",
dataSource = new kendo.data.DataSource({
transport: {
read: {
url: crudServiceBaseUrl + "/PCByStatus",
filter: {field: "status", value: "2" }
dataType: "json",
update: {
url: crudServiceBaseUrl + "/PC/Update",
dataType: "json"
},
destroy: {
url: crudServiceBaseUrl + "/PC/Destroy",
dataType: "json"
},
create: {
url: crudServiceBaseUrl + "/PC/Create",
dataType: "json"
},
parameterMap: function(options, operation) {
if (operation !== "read" && options.models) {

I still cannot get this to work and am a bit stumped.
I have two rest services, one returns all data, one takes "status" as a part and return a subset of the data that equals the parm.
The URL is:
http://localhost/scoApps/PC/PCApp.nsf/rsPC.xsp/PCByStatus?status=2
When entered into browser I get the correct number of records.
So I changed the code (see below). I have included all of the code for the CSJS:
$(document).ready( function() {
// Double Click On row
$("#grid").on(
"dblclick",
" tbody > tr",
function() {
var grid = $("#grid").data("kendoGrid");
var row = grid.dataItem($(this));
window.location.replace("xpFormPC.xsp" + "?key=" + row.unid + "target=_self");
});
// Add hover effect
addExtraStylingToGrid = function() {
$("table.k-focusable tbody tr ").hover( function() {
$(this).toggleClass("k-state-hover");
});
};
// Search
$("#search").keyup( function() {
var val = $('#search').val();
$("#grid").data("kendoGrid").dataSource.filter( {
logic : "or",
filters : [ {
field : "serialNumber",
operator : "contains",
value : val
}, {
field : "officeLoc",
operator : "contains",
value : val
}, {
field : "model",
operator : "contains",
value : val
} ]
});
});
var crudServiceBaseUrl = "rsPC.xsp",
dataSource = new kendo.data.DataSource({
transport: {
read: {
url: crudServiceBaseUrl + "/PCByStatus",
dataType: "json"
},
update: {
url: crudServiceBaseUrl + "/PC/Update",
dataType: "json"
},
destroy: {
url: crudServiceBaseUrl + "/PC/Destroy",
dataType: "json"
},
create: {
url: crudServiceBaseUrl + "/PC/Create",
dataType: "json"
},
parameterMap: function(options, operation) {
if (operation == "read"){
options.field = "status"
options.value = "2"
return options;
}
if (operation !== "read" && options.models) {
return {models: kendo.stringify(options.models)};
}
}
},
batch: true,
pageSize: 20,
scrollable: {
virtual: true
},
height: 543,
schema: {
model: {
id: "PCId",
fields: {
PCId: {type:"string"},
serialNumber: {type: "string"},
officeLoc: {type: "string"},
unid: {type:"string"},
model: {type:"string"},
checkInDate: {type: "string"}
}
}
}
});
// Grid
grid = $("#grid").kendoGrid( {
dataSource: dataSource,
columns : [ {
field : "serialNumber",
title : "Serial Number"
}, {
field : "model",
title : "Model"
}, {
field : "officeLoc",
title : "Office Location"
}, {
field : "checkInDate",
title : "Check In Date",
template: "#= kendo.toString(kendo.parseDate(checkInDate, 'yyyy-MM-dd'), 'MM/dd/yyyy') #"
} ],
pageable: {
refresh: true,
pageSizes: true,
buttonCount: 5
},
dataBound : addExtraStylingToGrid,
reorderable : true,
filterable : true,
scrollable : true,
selectable : true,
sortable : true
});
// Edit
function onEdit(e) {
}
// Change
function onChange(args) {
var model = this.dataItem(this.select());
ID = model.ID;
}
;
});
What am I doing wrong?
=========================================
I have a workaround. Or possibly this is the way it is supposed to be done.
var crudServiceBaseUrl = "rsPC.xsp", dataSource = new kendo.data.DataSource(
{
transport : {
read : {
url : crudServiceBaseUrl
+ "/PCByStatus?status=2",
dataType : "json"
},
Now I just construct the URL I want. Not so elegant I suppose, but it works.

Filter is used for client side data unless you set serverFiltering to true.
Here is the filter kendo documentation and the serverFiltering documentation.
I use parameterMap when I need to send parameters that are not created by filtering the control that I'm using. The kendo documentation provides an example using parameterMap.
Here is an example of how I've used it in the past:
var appsDataSource = new kendo.data.DataSource({
transport: {
read: {
url: apiUrl + "App"
},
parameterMap: function (data, action) {
if (action === "read") {
data.lobid = lobId;
data.parent = isParent;
return data;
} else {
return data;
}
}
}
});
Try changing the parameterMap:
parameterMap: function(options, operation) {
if (operation == "read"){
options.field = "status";
options.value = "2";
return options;
}
if (operation !== "read" && options.models) {
return {models: kendo.stringify(options.models)};
}
}
and update the read definition to remove filter. One thing to consider is that you are not returning anything from the read method if it doesn't meet the criteria of not being a read and options is not null. That leaves out any other combination that isn't obviously handled in your existing code.
