I have this document in mongodb
In return
i want translation[0] with auto-publish, color and boolean.
Note: Without using aggregation or putting other sibling's value 1
You can use forEach on your cursor:
db.test.find({}).forEach(function(doc){
if (doc.hasOwnProperty('translation')){
var newdoc = {};
newdoc = doc.translation[0];
newdoc['auto-publish'] = doc['auto-publish'];
newdoc['color'] = doc['color'];
newdoc['boolean'] = doc['boolean'];
print(tojson(newdoc));
}
})
I don't think there's any other way to re-organize document as you need without using aggregation.

}
All I want is for this specific id, to completely delete the lightControl element from metadata. I have tried $pull, but I am probably missing something. Any ideas? Thank you in advance!
Your lightControl is not in array, for nested property, use the dot wrapped in doublequotes:
MongoDB shell:
db.getCollection('yourCollectionName').update({},{$unset:{
"metadata.lightControl":""
}})
In case you have a list of objects with _id(s) instead of updating directly, assume Node.js client for MongoDB is used:
// import mongodb from "mongodb"; // ES6
const mongodb = require("mongodb");
var client = MongoClient(...);
var coll = client["yourDbName"]["yourCollectionName"];
var objs = []; // <-- The array with _id(s)
for (let i=0; i<objs.length; i++){
let id = mongodb.ObjectID(objs[i]["_id"]);
coll.update({ _id:id },{$unset:{ "metadata.lightControl":"" }});
}
I have this array of documents, I would like to put "table" on the same level like mastil_antenas and other variables. how Can I do that with aggregate?
I'm trying with the aggregate $project but I can't get the result.

Starting from MongoDB version 3.4 you could use $addFields to do this.
//replace products with what makes sense in your database
db.getCollection('products').aggregate(
[
{ //1 add the properties from subdocument table to documents
$addFields: {
"documents.tecmast" : "documents.0.table.tecmast",
"documents.frecmast" : "documents.0.table.frecmast",
"documents.secmast" : "documents.0.table.secmast",
"documents.untitled440" : "documents.0.table.untitled440"
}
},
{
//(optional) 2 remove the table property from the documents
$project: {"documents.table" : 0}
}
]
)
Step 1: use $addFields to grab properties from table inside documents.table and put them on documents
Step 2: (optional) remove property "table" from documents.
I hope this helps!!!

I am literally following the mapreduce debug steps from official mongo documentation.
Here's what my mapreduce script looks like:
var map = function() {
emit("1", this._id);
};
var emit = function(key, value) {
print("emit");
print("key: " + key + " value: " + tojson(value));
}
var myDoc = db.getCollection("abc").find({}).limit(1);
map.apply(myDoc);
And it always produces the result like this:
MongoDB shell version: 2.4.6
connecting to: test
emit
key: 1 value: undefined
I expect the script to emit the _id since it clearly exists in the document but it doesn't.
What might be possible cause of this?
find() always returns a cursor.
Replace it with findOne()
var myDoc = db.getCollection("abc").findOne({});
Or store the documents in an Array using toArray()
var myDoc = db.getCollection("abc").find({}).limit(1).toArray()[0];
I want to update a particular property in a nested mongo document
{
"_id" : ObjectId("55af76e60b0e4b318ba822ec"),
"make" : "MERCEDES-BENZ",
"model" : "E-CLASS",
"variant" : "E 250 CDI CLASSIC",
"fuel" : "Diesel",
"cc" : 2143,
"seatingCapacity" : 5,
"variant_+_fuel" : "E 250 CDI CLASSIC (Diesel)",
"make_+_model_+_variant_+_fuel" : "MERCEDES-BENZ E-CLASS E 250 CDI CLASSIC (Diesel)",
"dropdown_display" : "E-CLASS E 250 CDI CLASSIC (Diesel)",
"vehicleSegment" : "HIGH END CARS",
"abc" : {
"variantId" : 1000815,
"makeId" : 1000016,
"modelId" : 1000556,
"fuelId" : 2,
"segmentId" : 1000002,
"price" : 4020000
},
"def" : {
"bodyType" : 1,
"makeId" : 87,
"modelId" : 21584,
"fuel" : "DIESEL",
"vehicleSegmentType" : "E2"
},
"isActive" : false
}
This is my document. If I want to add or update a value for key "nonPreferred" inside "abc", how do I go about it?
I tried it with this query:
db.FourWheelerMaster.update(
{ "abc.modelId": 1000556 },
{
$Set: {
"abc": {
"nonPreferred": ["Mumbai", "Pune"]
}
}
},
{multi:true}
)
but it updates the whole "abc" structure, removed all key:values inside it and kept only newly inserted key values like below
"abc" : {
"nonPreferred" : [
"Mumbai",
"Pune"
]
},
Can anyone tell me how to update only particular property inside it and not all the complete key?
Instead of using the $set operator, you need to push that array using the $push operator together with the $each modifier to append each element of the value separately as follows:
db.FourWheelerMaster.update(
{ "abc.modelId": 1000556 },
{
"$push": {
"abc.nonPreferred": {
"$each": ["Mumbai", "Pune"]
}
}
},
{ "multi": true }
)
I am newbie in MongoDB. I have stored data inside mongoDB in below format
"_id" : ObjectId("51d5725c7be2c20819ac8a22"),
"chrom" : "chr22",
"pos" : 17060409,
"information" : [
{
"name" : "Category",
"value" : "3"
},
{
"name" : "INDEL",
"value" : "INDEL"
},
{
"name" : "DP",
"value" : "31"
},
{
"name" : "FORMAT",
"value" : "GT:PL:GQ"
},
{
"name" : "PV4",
"value" : "1,0.21,0.00096,1"
}
],
"sampleID" : "Job1373964150558382243283"
I want to update the value to 11 which has the name as Category.
I have tried below query:
db.VariantEntries.update({$and:[ { "pos" : 117199533} , { "sampleID" : "Job1373964150558382243283"},{"information.name":"Category"}]},{$set:{'information.value':'11'}})
but Mongo replies
can't append to array using string field name [value]
How one can form a query which will update the particular value?
You can use the $ positional operator to identify the first array element to match the query in the update like this:
db.VariantEntries.update({
"pos": 17060409,
"sampleID": "Job1373964150558382243283",
"information.name":"Category"
},{
$set:{'information.$.value':'11'}
})
In MongoDB you can't adress array values this way. So you should change your schema design to:
"information" : {
'category' : 3,
'INDEL' : INDEL
...
}
Then you can adress the single fields in your query:
db.VariantEntries.update(
{
{"pos" : 117199533} ,
{"sampleID" : "Job1373964150558382243283"},
{"information.category":3}
},
{
$set:{'information.category':'11'}
}
)
