I have an array of IDs like for example
[id1,id2,id3,......]
and i have a collection with documents for example
{
"_id" : ObjectId("1111111111111"),
"phoneNumber" : "1234567891",
"fid" : "id1",
"pid" : "abcd",
"activeFlag" : true
},
{
"_id" : ObjectId("2222222222"),
"phoneNumber" : "1234567891",
"fid" : "id1",
"pid" : "efgh",
"activeFlag" : true
},
{
"_id" : ObjectId("33333333333"),
"phoneNumber" : "1234567891",
"fid" : "id2",
"pid" : "xyz",
"activeFlag" : true
},
{
"_id" : ObjectId("4444444444444"),
"phoneNumber" : "1234567891",
"fid" : "id3",
"pid" : "mnop",
"activeFlag" : true
}
i want to find the documents with fid which match IDs in my array of IDs ,
also i want to sort it according to _id and limit is 9.
if id1 taken then i need all documents which is having fid as id1, like that.
This script should do the trick
var listId = ["id1", "id2", "id3"];
var cursor = db.collection.find({fid: {$in: listId}}).sort({_id: 1}).limit(9);
// iterate over documents
if (cursor != null && cursor.hasNext()){
while (cursor.hasNext()){
// print documents
print(JSON.stringify(cursor.next()));
}
}
to run it, create a file names script.js, copy the code above inside it and then run the command
mongo databaseName < script.js

i have a list schema and a question set schema. the quetsionSet schema is embedded inside the list schema. its working fine but how can i update anything inside the array of embedded document i.e. here i want to change the listname of all the documents inside questionSet (array of questionSet documents).
here is an example of my list document model
{ "_id" : ObjectId("60f2cc07275bbb30d8cb268e"),
"listName" : "dsa",
"aboutList" : "dsa queestions",
questionSet" : [ { "solved" : false,
"_id" : ObjectId("60f2cc12275bbb30d8cb2695"),
"topic" : "array",
"name" : "array is best",
"url" : "www.arr.com",
"listname" : "dsa",
"__v" : 0 },
{ "solved" : false,
"_id" : ObjectId("60f2cc1b275bbb30d8cb269d"),
"topic" : "linked list",
"name" : "reverse list",
"url" : "www.list.com",
"listname" : "dsa",
"__v" : 0 }
],
"__v" : 2
}
you can use the following in your case
db.<collection_name>.updateOne(
{ "_id" : ObjectId("60f2cc07275bbb30d8cb268e")},
{
$set: {
'questionSet.$[].listname': "javascript"
}
}
)
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"),

},
"machines" : [
{
"idPlotBind" : 1,
"ip" : "",
"mac" : "18-5F-00-4A-FE-F4",

{

"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

So as you can see this is the single document that contains the whole data of array i want to fetch the orders whose status is cancel from this order array.
So for that i have use :-
var orderDetails =
orders.find({"ListOrdersResult.Orders.Order":{$elemMatch:
{ OrderStatus:"Canceled"}}}).fetch();
Also i tried with:-
orders.find({"ListOrdersResult.Orders.Order.OrderStatus":'Canceled'}).fetch();
So this will return the whole document that contains status as canceled and other as well but i want only selected result from the document that contains status as pending.
So is there any way in mongoDb to query a selected value from a single document that contains nested array of arrays as object.
Or I need to staore the values into diff diff documents thats only the solution.
Any help would be appriciated please contribute
Thanks!
You can go with any meteor aggregate package. You can use match and then group the data then send it to client-side.Like :
var ordersLines = orders.aggregate([
{$unwind : "$ListOrdersResult.Orders.Order"},
{$match : { OrderStatus:"Canceled"} },
{$project : {
OrderType : '$ListOrdersResult.Orders.Order.OrderType'
....
}
}
]);
return ordersLines;
But I suggest you go with a different document.
I am trying to get only the ObjectId's from One specific Document that is embedded in the projects Array.
Basically I am trying to make a database that will have users and each user will have there own projects.
Thank you !
db.users.find().pretty()
{
"_id" : ObjectId("5762c0cf2b9a78006373a684"),
"name" : "seq",
"pass" : "seq",
"projects" : [
{
"pid" : ObjectId("5762c0ba2b9a78006373a682"),
"name" : "aaa"
},
{
"pid" : ObjectId("5762c0ba2b9a78006373a683"),
"name" : "bbb"
}
]
}
{
"_id" : ObjectId("5762c28d2b9a78006373a687"),
"name" : "leq",
"pass" : "leq",
"projects" : [
{
"pid" : ObjectId("5762c2892b9a78006373a685"),
"name" : "ccc"
},
{
"pid" : ObjectId("5762c2892b9a78006373a686"),
"name" : "ddd"
}
]
}
let say we want two pids
{"pid" : ObjectId("5762c0ba2b9a78006373a682")} and
{"pid" : ObjectId("5762c2892b9a78006373a686"),}
and only inner documents
so required response should look like:
{
"_id" : ObjectId("5762c0ba2b9a78006373a682"),
"name" : "aaa"
},{
"_id" : ObjectId("5762c2892b9a78006373a686"),
"name" : "ddd"
}
Aggregation framework can manipulate documents, match only needed ones and transform inner structure by project phase:
var match = {
$match : {
"projects.pid" : {
$in : [ObjectId("5762c0ba2b9a78006373a682"),
ObjectId("5762c2892b9a78006373a686")]
}
}
}
var unwind = {
$unwind : "$projects"
};
// now move array objet as top level object
var project = {
$project : {
_id : "$projects.pid",
name : "$projects.name",
// list other fields here
}
}
db.vic.aggregate([match, unwind, match, project])
This question already has an answer here:
Updating template with session variable and subscription/publication only updates with previous query and appends information
(1 answer)
Closed 7 years ago.
Description of the problem:
I have two collections videos and specs. videos collection has a key called spec which corresponds to a specs id. Both collections are not empty.
My Template Helper:
Template.List.helpers({
videos: function(){
var vids = Videos.find({ online: false}).fetch();
return vids.map(function(value){
console.log("id: " + value.spec);
console.log(Specs.find({ id: value.spec }).fetch());
//Issue here
value.specName = Specs.find({ id: value.spec }).fetch()[0].name;
return value;
});
}
});
As you can see in my template helper I loop through the video array and add specName to the array.
The main problem comes from this specific line:
value.specName = Specs.find({ id: value.spec }).fetch()[0].name;
and more specifically this line: Specs.find({ id: value.spec }).fetch()
which will return null every time.
What I've tried:
Naturally, my first thought would be to check what value.spec returns. And it returns an int between 1 and 15 (included) which is right. If value.spec is right, then how come the find() doesn't return anything?
I then decided to hard set it and tried this:
Specs.find({ id: 2}).fetch()
And this worked. Which is weird because on multiple occasions value.spec returns 2...
I've also tried intParse(value.spec) just in case, however that didn't work either.
Question
Why does Specs.find({ id: value.spec }).fetch() return null knowing that value.spec is set correctly and that a hard coded number works?

I've been stuck on this problem for a couple hours, I didn't want to post this on SO since I do believe it's a simple problem. However, it is mind boggling.
The problem here is the publication/subscription issue. You did not mention it, how do you handle publications and subscriptions but that is most likely the issue. What is happening is that when you browse your videos collection, which subscription is ready (since you hae any data in it) here: Videos.find({ online: false}) that not necessarly means that (in that precise moment) subscription handling Spec collection is ready as well. So even if on the server the query is working, on the client it's null, because the data are not synced between client and server YET. so you have to wait until both subscriptions are ready somehow. You can use template subscriptions, or waitOn function in your router.
First of all check on server side that your publication and subscription is ready and returning you back data check this like as
Meteor.publish('Videso', function () {
var result= Videso.find({});
console.log(result);
return result
});
if console.log returning you records on server side i have a solution then your
problem
the solution of your problem is that
Template.List.helpers({
videos: function(){
var vids = Videos.find({ online: false}).map(function (value) {
console.log("id: " + value.spec);
var idValue = Specs.findOne({ "id": value.spec })
console.log("idValue===",idValue)
return _.extend(value, idValue);
});
console.log(vids); //here merged data of both table having
// relvent record will returned
return vids;
}
});
Just implement it and check data on your template it will be ready for you and vote me then :)
