How to fetch specific fields in Mongo DB only values without keys? - node.js

My data set is following:
{ "_id" : "EVNQUERY-k9Uoo74Q3WcdmU", "event_data" : "{\"data\":\"helo\"}", "event_name" : "onOemPushAlert", "timestamp_start" : 1452678481433, "timestamp_end" : 1452678481433, "sender" : "USR-ADMIN", "status" : "pending", "query" : { "user" : { "and" : [ { "email" : { "eq" : "" } } ] } }, "updated_on" : ISODate("2016-01-13T09:48:01.459Z"), "created_on" : ISODate("2016-01-13T09:48:01.459Z") }
{ "_id" : "EVNQUERY-yAKmrbzs2JeaUY", "event_data" : "{\"data\":\"ji\"}", "event_name" : "onOemPushAlert", "timestamp_start" : 1452681060159, "timestamp_end" : 1452681060159, "sender" : "USR-ADMIN", "status" : "pending", "query" : { "user" : { "###and###" : [ { "email" : { "eq" : "" } } ] } }, "updated_on" : ISODate("2016-01-13T10:31:00.223Z"), "created_on" : ISODate("2016-01-13T10:31:00.223Z") }
{ "_id" : "EVNQUERY-0NeCstt2eJchDZ", "event_data" : "{\"data\":\"hyg\"}", "event_name" : "onOemPushAlert", "timestamp_start" : 1452681073882, "timestamp_end" : 1452681073882, "sender" : "USR-ADMIN", "status" : "pending", "query" : { "user" : { "###and###" : [ { "email" : { "eq" : "" } } ] } }, "updated_on" : ISODate("2016-01-13T10:31:13.897Z"), "created_on" : ISODate("2016-01-13T10:31:13.897Z") }
and i am running following query
db.eventqueries.find({},{_id:1})
but it give me
{ "_id" : "EVNQUERY-k9Uoo74Q3WcdmU" }
{ "_id" : "EVNQUERY-yAKmrbzs2JeaUY" }
{ "_id" : "EVNQUERY-0NeCstt2eJchDZ" }
but what i want is
["EVNQUERY-k9Uoo74Q3WcdmU", "EVNQUERY-yAKmrbzs2JeaUY", "EVNQUERY-0NeCstt2eJchDZ"]


Perform a distinct() query against the _id field on the collection:
db.eventqueries.distinct("_id")
In the node.js driver run the distinct() command which would have a callback with the results:
collection.distinct("_id", function(err, docs) {
if (err) { /* handle error */ };
console.log(docs);
});


You can use aggregation to achieve what you want. You can try this out
db.eventqueries.aggregate([
{
$group : {
keys : { $push : "_id" }
}
}
])

Mongo update to many query

does anyone know how to change a propertie value in mongo
from
i changed JSON.units[0].services[0].label from etiket controle to AuditLabel
i tried this:
db.getCollection('assortiment').updateMany({"units.$[].services.$[].label": "etiket controle"},{ "$set": { "units.$[].services.$[].label": "AuditLabel" }})
but no succes because it dont select anything
{
"_id" : "764",
"meta" : {
"groupsId" : "764",
"type" : "DRYGR"
},
"units" : [
{
"unit" : "BASE_UNIT_OR_EACH",
"gtin" : "08711728556206",
"services" : [
{
"label" : "etiket controle",
"collection" : "gtins"
}
]
}
]
}
to
{
"_id" : "764",
"meta" : {
"groupsId" : "764",
"type" : "DRYGR"
},
"units" : [
{
"unit" : "BASE_UNIT_OR_EACH",

{
"units.services.label": "etiket controle"
},
{
"$set":
{ "units.$[].services.$[].label": "AuditLabel" }

update particular single subdocument in nested array in nodejs mongodb

I am new to nodejs and mongo db. I have nested subdocument type schema in mongo. Document type is Process => Subprocess => tasks => configs. These are in the format of nested arrays and can be multiple.
{
"_id" : ObjectId("5bcec0ee711fe511f4848c1d"),
"process_title" : "customer acquisition",
"subprocess" : [
{
"_id" : ObjectId("5bcec0f8711fe511f4848c1e"),
"subprocess_title" : "application",
"tasks" : [
{
"_id" : ObjectId("5bcec158711fe511f4848c1f"),
"task_title" : "pre screening",
"task_slug" : "pre-screening",
"task_configs" : [
{
"_id" : ObjectId("5bcec4b912582b01b84fe47a"),
"next_task" : "thanks"
}
]
},
{
"_id" : ObjectId("5bcec190711fe511f4848c20"),
"task_title" : "thanks",
"task_slug" : "thanks",
"task_configs" : [
{
"_id" : ObjectId("5bcec469ab23ab1fc0bbb9ed"),

},
{

"updated" : ISODate("2018-10-23T06:34:22.676Z"),
"__v" : 0
}
Now I want to update task_configs for a particular task. I am updating task_config on the basis of task_slug.

I found a way myself to update above query.
Workflow.updateOne({ "_id": new ObjectId(req.body.process_id), "subprocess._id": new ObjectId(req.body.sub_process_id), "subprocess.tasks.task_slug": req.body.task_slug },
{
$set: {
'subprocess.$.tasks.$[j].task_configs': req.body.task_configs
}
},
{
arrayFilters: [
{
"j.task_configs": req.body.task_configs
}]
})
.then(function (resp) {
console.log(resp)
res.json({ status: 'success', resp });
}).catch(function (err) {
res.status(500).json(err);
})

TODO
I need to remove for example this element { "_id" : ObjectId("5b633025579fac22e74bf3c2"), "phone" : "+84404040404"}
WHAT I DID
GroupEvents.update({}, {$pull:{FLAGS:{$elemMatch:{toSent:{phone: "+84404040404"} }}}},function(err,ret){
if(err)
console.log("error"+err);
if(ret)
console.log(ret);
});
It remove all what's inside toSent event if it doesn't match.
Any help please

You need to use $ positional operator instead of $elemMatch here
GroupEvents.update(
{ "Flags.toSent.phone": "+84404040404" },
{ "$pull": { "FLAGS.$.toSent": { "phone": "+84404040404" }}},
)
If you want remove from every element of FLAGS array this you need to use $[] the all positional operator
GroupEvents.update(
{ "Flags.toSent.phone": "+84404040404" },
{ "$pull": { "FLAGS.$[].toSent": { "phone": "+84404040404" }}},
)

I tried and It worked for me. Sorry
db.getCollection("transactions").aggregate(

"items" : {
"$push" : "$$ROOT"
}
}
},
{
"$project" : {
"orderId" : "$_id",
"items" : "$items",
"_id" : 0
}
},
{
"$unwind" : {
"path" : "$items",
"preserveNullAndEmptyArrays" : false
}
},
{
"$group" : {
"_id" : "$items.factoryId",
"orders" : {
"$push" : "$$ROOT"

"module" : [
{

}
}
]
}
}
}
}
}

You can use a function as your $where operator:
collection.find({ $where: function() {
var productDataRecord = this.json["query_by_gtin_response:queryByGtinResponse"]["productData"]["productDataRecord"];
var status = productDataRecord["module"][1]["product_tracking_information_module"].status;
return (status.value == "CERTIFIED")
}})
