Using mongoose on node.js I'm trying to find all games where player game.players.id equals the id I passed.
Schema:
var Game = mongoose.Schema({
id: String,
date: { type: Date, default: Date.now },
game: Object,
isOnline: Boolean
});
I'm not sure what is wrong in this function but it returns empty array:
var specificGameStatistics = function (user, game) {
var deferred = q.defer()
Game.find({ "game.players.id" : user, "game.rules.gameType": game.gameType, "game.rules.quatro": game.quatro}, function(err, data) {
deferred.resolve(data);
});
return deferred.promise;
}
////////////////////USAGE///////////////
var testGame = {rules: {gameType : 1, quatro : null}}
UsersCtrl.specificGameStatistics(data.id, testGame).then(function(userData) {
console.log(userData);
});
And here is the example of the game already saved in database:
{
"isOnline" : true,
"game" : {
"numberOfPlayers" : NumberInt("1"),
"players" : [
{
"id" : "58a2c0ecd8ba9f8602836870",
"name" : "PlayerName",
"type" : NumberInt("1"),
"avgStatistic" : "30.00",
"numbersHit" : NumberInt("1"),
"totalScore" : NumberInt("60"),
..............................
}
], //there is more players here
"rules" : {
"gameType" : NumberInt("1"),
"quatro" : null,
"rounds" : NumberInt("1"),
} // there is more in JSON object
...............................
"_id" : ObjectId("58aed4aeea20ecdf0c426838"),
"date" : ISODate("2017-02-23T13:25:18.284+01:00"),
"__v" : NumberInt("0")
}
I have tested the player ID to be equal and it is but still it returns empty array. Test code:
///////////TEST//////////////
console.log(data.id, "58a2c0ecd8ba9f8602836870");
if (data.id === "58a2c0ecd8ba9f8602836870") {console.log("this is true");}
var testGame = {rules: {gameType : 1, quatro : null}}
UsersCtrl.specificGameStatistics(data.id, testGame).then(function(userData) {
console.log(userData);
});
//////////TEST///////////////
and it returns:
58a2c0ecd8ba9f8602836870 58a2c0ecd8ba9f8602836870
this is true
[]
--------------------------------------------------------------------------------------------------------
Answer: With help of Deividas Karžinauskas the solution is:
Game.where('game.players.id', user).where('game.rules.gameType', game.rules.gameType).find({}, function(err, data) { //, "game.rules.quatro": game.quatro
deferred.resolve(data);
});
This is because of the additional rules that you specify ({gameType : 1, quatro : null}), which do not exist in the player object (
{
"id" : "58a2c0ecd8ba9f8602836870",
"name" : "PlayerName",
"type" : NumberInt("1"),
"avgStatistic" : "30.00",
"numbersHit" : NumberInt("1"),
"totalScore" : NumberInt("60"),
..............................
}
). You can confirm this by simply looking for a game by id.
If you want to add these rules then you should find all games which match these rules and then look for the games of a specific player.

I've to push a given array of Number values into a selected Document inside my MongoDB database.
The Document that I'm going to update as the following structure:
{
"_id" : {
"id" : 17,
"type" : "f"
},
"__v" : 0,
"created_at" : ISODate("2017-03-22T11:16:21.403Z"),
"token" : {
"expDate" : ISODate("2017-12-31T00:00:00Z"),
"token" : "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJlbWFpbCI6ImFsYWRpbkBjb25zb3J6aW9jZXIuaXQiLCJleHAiOjE1MTQ2Nzg0MDB9.QvbT146bA_KH5XA7MH8ASXm9cr3sPZChJ3prYyDireI"
},
"updated_at" : ISODate("2017-07-24T09:42:33.741Z"),
"plots" : {
"idPlot" : [
23570,
23475
]
},
"machines" : [
{
"idPlotBind" : 1,
"ip" : "",
"mac" : "18-5F-00-4A-FE-F4",
"irrId" : 31,
"_id" : ObjectId("59084f527d634d301338aac6"),
"addr" : "pialadin.ddns.net"
},
{
"idPlotBind" : null,
"ip" : "",
"mac" : "12-01-02-FE-AB-B2",
"irrId" : 35,
"_id" : ObjectId("59084f7d7d634d301338aac7")
}
]
}
I'm using the Mongoose library for JS, and the accused query is this one:
userSchema.findOneAndUpdate({$and:[{ '_id.id': resData.PlotRows.IdUser}, {'_id.type': 'f'}]},{$addToSet:{'plots.$.idPlot': {$each: plotData}}}, {upsert: false}, function(err, usr){
if(err){
console.log(err);
return;
}
});
But when I try to execute it, gives me back:
Error: Can't use $each with Number
What I am trying to do.
I have a userSchema that contains a list of operationCountSchemaobjects. What I am trying to do, is to create a static method that updates the count field on one of these operation count subdocuments if it exists (identified by a month_id) field. If an operationCountSchema document does not exist for the current month, it should create a new document. Is there a way to achieve this behaviour in mongoose? I have tried using upsert to no avail. How would one do this? Thanks.
CODE
var operationCountSchema = mongoose.Schema({
month_id: String,
count: { type: Number, default: 0 }
}, {_id : false});
var userSchema = mongoose.Schema({
username : { type: String, unique: true, required: true },
email: { type: String, unique: true, required: true },
password: String,
operation_counts: [operationCountSchema]
});
userSchema.statics.incrementOperationCount = function(userID, callback) {
var currDate = new Date();
var dateIdentifier = currDate.getFullYear() + "-" + currDate.getMonth();
//NEED TO INCREMENT OPERATION COUNT IF ONE FOR MONTH EXISTS,
//ELSE IF IT DOES NOT EXIST, CREATE A NEW ONE.
}
Also, any suggestions on alternative ways in which this functionality can be achieved are welcome.
I think you want findOneAndUpdate() with upsert : true:
operationCountSchema.findOneAndUpdate({
month_id : dateIdentifier,
}, {
$inc : { count : 1 }
}, {
upsert : true
}, callback);
(untested)
You can do it in two steps, here is a example in mongo shell:
mongos> db.collection.findOne()
{
"username" : "mark",
"email" : "admin#example.com",
"password" : "balalalala",
"operation_counts" : [
{
"month_id" : "2016-05",
"count" : 6
}
]
}
First, make sure the subdoc exists, if not just create one use $addToSet.
mongos> db.collection.update({username:"mark", "operation_counts.month_id": {$ne:"2016-05"}}, {$addToSet: {"operation_counts":{month_id: "2016-05", count:0}}})
WriteResult({ "nMatched" : 0, "nUpserted" : 0, "nModified" : 0 })
// only update when the subdoc of specified month not exists
mongos> db.collection.update({username:"mark", "operation_counts.month_id": {$ne:"2016-06"}}, {$addToSet: {"operation_counts":{month_id: "2016-06", count:0}}})
WriteResult({ "nMatched" : 1, "nUpserted" : 0, "nModified" : 1 })
mongos> db.collection.findOne()
{
"_id" : ObjectId("575636c21e9b27fe715df654"),
"username" : "mark",
"email" : "admin#example.com",
"password" : "balalalala",
"operation_counts" : [
{
"month_id" : "2016-05",
"count" : 6
},
{
"month_id" : "2016-06",
"count" : 0
}
]
}
Then, increment the count field.
mongos> db.collection.update({username:"mark", "operation_counts.month_id": "2016-06"}, {$inc:{ "operation_counts.$.count":1 }})
WriteResult({ "nMatched" : 1, "nUpserted" : 0, "nModified" : 1 })
mongos> db.collection.findOne()
{
"_id" : ObjectId("575636c21e9b27fe715df654"),
"username" : "mark",
"email" : "admin#example.com",
"password" : "balalalala",
"operation_counts" : [
{
"month_id" : "2016-05",
"count" : 6
},
{
"month_id" : "2016-06",
"count" : 1
}
]
}
So you can have a mongoose.find() or mongoose.findOne() and check if the sub-document exists. If it doesn't we can create the a new object and if it does, we can increment and save.
Here I'm using mongoose.findOne(). Refer to the docs here.
userSchema.statics.incrementOperationCount = function(userID, callback) {
var currDate = new Date();
var dateIdentifier = currDate.getFullYear() + "-" + currDate.getMonth();
//NEED TO INCREMENT OPERATION COUNT IF ONE FOR MONTH EXISTS,
//ELSE IF IT DOES NOT EXIST, CREATE A NEW ONE.
operationCountSchema.findOne({'month_id': dateIdentifier}, function(err, subDoc) {
// If there is an error in finding the document, catch them
if(err) {
// Handle errors
return err;
}
// If you find a document, increment the `count` and save
if(subDoc) {
subDoc.count += 1;
subDoc.save(function(err2) {
if(err2) {
// Handle errors
return err2;
} else {
return "Success";
}
});
}
// If no document is found, create a new one
else {
// Populate the values to create the object
var data = {
"month_id": dateIdentifier,
"count": 0
};
operationCountSchema.create(data, function(err3, subDoc) {
if(err3) {
// Handle errors
return err3;
}
// Else return success
return "Success";
});
}
});
};
Let me know if I got your question worng or didn't address something.
I'm using Meteor with MongoDB and can't seem to figure out how to access a single field from the objects in an object array.
My documents:
{
"_id" : "p6c4cSTb3cHWaJqpG",
"createdAt" : ISODate("2016-05-11T11:30:11.820Z"),
"username" : "admin",
"contacts" : [
{
"when" : ISODate("2016-05-11T11:30:32.350Z"),
"who" : "4YBufbE9PByJBkasy"
},
{
"when" : ISODate("2016-05-25T11:52:49.745Z"),
"who" : "z792kEEYbxyzyEAKp"
},
{
"when" : ISODate("2016-05-26T13:47:43.439Z"),
"who" : "4YBufbE9PByJBkasy"
},
{
"when" : ISODate("2016-05-26T13:48:22.828Z"),
"who" : "4YBufbE9PByJBkasy"
}
]
}
I want to check if a userId is in any of the objects, specifically in the who fields.
My Server-side code:
var me = Meteor.userId();
var findMe = Meteor.users.findOne(me);
if (_.include(findMe.contacts, {who: 4YBufbE9PByJBkasy})){
console.log("found in array");
}else{
console.log("Not found in array");
}
}
I have tried this several different ways, but came up with nothing.
When I console.log(findMe.contacts);, it returns the whole array like it should. but when I try to console.log(findMe.contacts.who);, it returns undefined.
Just need some direction on how to access the field of the object array. Thanks!
Looping through an array to see whether it contains a value is easily
done with Array.prototype.some:
var data = {
"_id" : "p6c4cSTb3cHWaJqpG",
"createdAt" : "2016-05-11T11:30:11.820Z",
"username" : "admin",
"contacts" : [
{
"when" : "2016-05-11T11:30:32.350Z",
"who" : "4YBufbE9PByJBkasy"
},
{
"when" : "2016-05-25T11:52:49.745Z",
"who" : "z792kEEYbxyzyEAKp"
},
{
"when" : "2016-05-26T13:47:43.439Z",
"who" : "4YBufbE9PByJBkasy"
},
{
"when" : "2016-05-26T13:48:22.828Z",
"who" : "4YBufbE9PByJBkasy"
}
]
};
var hascontact = function(contacts, id){
return contacts.some(function(contact){
return contact.who === id;
});
};
console.log(hascontact(data.contacts,'4YBufbE9PByJBkasy'));
console.log(hascontact(data.contacts,'z792kEEYbxyzyEAKp'));
console.log(hascontact(data.contacts,'asdfasdfasdfasdfa'));
I want to display content using a flat relational data structure (similar to that of Firefeed). Everything is working the way it should, except I can't figure out how to display the actual content. I'm struggling for a while now and I think I'm almost there actually, but something is still missing.
I have two references:
var userFeedRef = new Firebase(FIREBASE_URL).child("users").child($rootScope.currentUser.$id).child("feed");
var uploadsRef = new Firebase(FIREBASE_URL).child("uploads");
The JSON looks like this:
{
"uploads" : {
"-KGkxzQj0FM2CMAXo5Em" : {
"author" : "87a8b6c8-7f72-45c2-a8c5-bb93fe9d320d",
"date" : 1462184179564,
"name" : "Zizazorro",
"reasonUpload" : "Test",
"startSec" : 80,
"uploadTitle" : "Kid Ink - Promise (Audio) ft. Fetty Wap"
},
"-KGlCoD7kEa1k3DaAtlG" : {
"author" : "87a8b6c8-7f72-45c2-a8c5-bb93fe9d320d",
"date" : 1462188328130,
"name" : "Zizazorro",
"reasonUpload" : "Test2",
"startSec" : 80,
"uploadTitle" : "Kid Ink - Show Me ft. Chris Brown"
}
},
"users" : {
"87a8b6c8-7f72-45c2-a8c5-bb93fe9d320d" : {
"date" : 1459369248532,
"feed" : {
"-KGkxzQj0FM2CMAXo5Em" : true,
"-KGlCoD7kEa1k3DaAtlG" : true
},
"firstname" : "Bob",
"followers" : {
"e3de536b-03a1-4fb4-b637-ebcebaae55c6" : true
},
"following" : {
"e3de536b-03a1-4fb4-b637-ebcebaae55c6" : true
},
"regUser" : "87a8b6c8-7f72-45c2-a8c5-bb93fe9d320d",
"uploads" : {
"-KGkxzQj0FM2CMAXo5Em" : true,
"-KGlCoD7kEa1k3DaAtlG" : true
},
"username" : "Zizazorro"
},
"e3de536b-03a1-4fb4-b637-ebcebaae55c6" : {
"date" : 1459369285026,
"feed" : {
"-KGkxzQj0FM2CMAXo5Em" : true,
"-KGlCoD7kEa1k3DaAtlG" : true
},
"firstname" : "Anna",
"followers" : {
"87a8b6c8-7f72-45c2-a8c5-bb93fe9d320d" : true
},
"following" : {
"87a8b6c8-7f72-45c2-a8c5-bb93fe9d320d" : true
},
"regUser" : "e3de536b-03a1-4fb4-b637-ebcebaae55c6",
"username" : "Sven8k"
}
}
}
The problem is: How can I display the actual content of the upload, when there is only a ID reference? I need a reference to the IDs for a user (userFeedRef) and a reference to the actual content of those specific IDs, not all uploads (uploadsRef).
How can I display this user ng-repeat in my html? So for example: ng-repeat {{feed.reasonUpload}} for user1 has to show:
Test
Test2
EDIT I've looked at this example, but I can't figure out how to render the content on the actual html feed in my case
var commentsRef =
new Firebase("https://awesome.firebaseio-demo.com/comments");
var linkRef =
new Firebase("https://awesome.firebaseio-demo.com/links");
var linkCommentsRef = linkRef.child(LINK_ID).child("comments");
linkCommentsRef.on("child_added", function(snap) {
commentsRef.child(snap.key()).once("value", function() {
// Render the comment on the link page.
));
});
You can do something like this:
$scope.finalData = (Object).values($scope.firebaseData.uploads);
//$scope.firebaseData is data what you retrieving from firebase.
Hope this plunker will help you.
I am trying to delete "virtualNumber" : "12345" in the following document:
{
"_id" : ObjectId("50a9db5bdc7a04df06000005"),
"billingInfo" : null,
"date" : "dsfdsfsdfsd",
"description" : "sdfsdff",
"pbx" : {
"_id" : ObjectId("50a9db5bdc7a04df06000006"),
"did" : {
"1234567890" : {
"inventoryId" : "509df7547e84b25e18000001",
"didcountry" : "india",
"didState" : "bangalore",
"routeType" : "CallForward",
"didNumber" : "1234567890",
"didVirtualNumbers" : [
{
"virtualNumber" : "12345"
},
{
"virtualNumber" : "56789"
}
],
"id" : ObjectId("50a9db9acdfb4f9217000002")
}
},
},
I am using node.js, so I constructed a query in JavaScript:
var query = {_id: ObjectId("50a9db5bdc7a04df06000005")};
var obj = {};
obj["pbx.did.1234567890.didVirtualNumbers.virtualNumber"]=12345;
//problem
collection.update(query,{$pull:obj});
You need to match the array element like:
{"$pull": {"pbx.did.7259591220.didVirtualNumbers": {"virtualNumber": "12345"}}}
So you should change your code to:
obj["pbx.did.7259591220.didVirtualNumbers"]={"virtualNumber": "12345"};
Please refer to http://www.mongodb.org/display/DOCS/Updating#Updating-%24pull
It mentions the pull field should be an array.
