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 trying to fetch total replies where read values for a replies is true. But I am getting count value as 3 but expected value is 2 (since only two read value is true) through Aggregation function available in Spring Data Mongo. Below is the code which I wrote:
Aggregation sumOfRepliesAgg = newAggregation(match(new Criteria().andOperator(Criteria.where("replies.repliedUserId").is(userProfileId),Criteria.where("replies.read").is(true))),
unwind("replies"), group("replies").count().as("repliesCount"),project("repliesCount"));
AggregationResults<Comments> totalRepliesCount = mongoOps.aggregate(sumOfRepliesAgg, "COMMENTS",Comments.class);
return totalRepliesCount.getMappedResults().size();
Using AND Operator inside Criteria Query and passed two criteria condition but not working as expected. Below is the sample data set:
{
"_id" : ObjectId("5c4ca7c94807e220ac5f7ec2"),

I am having only 1 element in division_mapping's array and I want to find those documents whose dc in division_mapping is trade.
I have tried following:
"division_mapping":{$elemMatch:{$eq:{"dc":"trade"}}}})
Dont know what I am doing wrong.
//Maybe I have to unwind the array but is there any other way?
According to MongoDB documentation
The $elemMatch operator matches documents that contain an array
field with at least one element that matches all the specified query
criteria.
According to above mentioned description to retrieve only documents whose dc in division_mapping is trade please try executing below mentioned query
db.collection.find({division_mapping:{$elemMatch:{dc:'trade'}}})
So I have mongodb collection with documents that some of them have the same key (beatmapset_id):
{
"_id" : "fgq7SK7LnLbcFzgSb",
"beatmapset_id" : "59049",
"version" : "Hard",
"artist" : "UNDEAD CORPORATION",
"title" : "Yoru Naku Usagi wa Yume wo Miru",
"creator" : "Strawberry"
}
{
"_id" : "u7M8wibPwxuStNLSM",
"beatmapset_id" : "59049",
"version" : "jom's Taiko Muzukashii",
"artist" : "UNDEAD CORPORATION",
"title" : "Yoru Naku Usagi wa Yume wo Miru",
"creator" : "Strawberry"
}
{
"_id" : "ChRwdj7kbPL7oYgty",
"beatmapset_id" : "59049",
"version" : "jom's Taiko Oni",
"artist" : "UNDEAD CORPORATION",
"title" : "Yoru Naku Usagi wa Yume wo Miru",
"creator" : "Strawberry"
}
How do I publish only unique documents? Something like this:
Meteor.publish("beatmaps", function() {
return Beatmaps.find({ beatmapset_id: 1 }, { unique: true });
});
Now i solve this having 2 collections. One with all documents and one where I removed those documents with this code:
db.beatmaps.ensureIndex({ beatmapset_id: 1 }, { unique: true, dropDups: true });
But it's slow and when my first collection updates I also need to update second as well. I'm sure it can be done more consistent way.
Does this makes any sense when trying to add a sub-sub-item? (I'm new to mongo - be merciful :-))
question = db.questions.findOne({_id: ObjectId("529c5d44211c9a8c11000006")})
question.answers[0].votes.insert(...)
When I run this from the mongo console the result is an error saying [object object] does not have the method insert.
I have the following mongoDB Question Schema.
{
"__v" : 2,
"_creator" : ObjectId("529c5d2d211c9a8c11000005"),

I'm trying, given a questionId and an answerId to add a vote to the votes array (which is inside the answer). I can't seem to do it. Help?
insert is for adding whole new documents; when you just want to add a new element to an array field of an existing document, you can use update along with an operator like $push.
So, in the shell you would use something like this:
db.questions.update(
{_id: ObjectId("529c5d44211c9a8c11000006")},
{'answers.0.votes': {$push: voteToPush}})
I'm using groovy with mongodb. I have a result set but need a value from a different grouping of documents. How do I pull that value into the result set I need?
MAIN:Network data
"resource_metadata" : {
"name" : "tapd2e75adf-71",
"parameters" : { },
"fref" : null,
"instance_id" : "9f170531-79d0-48ee-b0f7-9bd2788b1cc5"}
I need the display_name for the network data result set which is contained in the compute data.
CPU data
"resource_id" : "9f170531-79d0-48ee-b0f7-9bd2788b1cc5",
"resource_metadata" : {
"ramdisk_id" : "",
"display_name" : "testinstance0001"}
You can see the resource_id and the Instance_id are the same values. I know there is no relationship I can do but trying to reach to see if anyone has come across this. I'm using the table model to retrieve data for reporting. Hashtable has been suggested to me but I'm not seeing that working. Somehow in the hasNext I need to include the display_name value. in the networking data so GUID number doesn't only valid name shows from compute data.
def docs = meter.find(query).sort(sort).limit(50)\
while (docs.hasNext()) { def doc = docs.next()\
model.addRow([ doc.get("counter_name"),doc.get("counter_volume"),doc.get("timestamp"),\
doc.get("resource_metadata").getString("mac"),\
doc.get("resource_metadata").getString("instance_id"),\
doc.get("counter_unit")]
as Object[]);}
Full document:
1st set where I need the network data measure with no name only id {resource_metadata.instance_id}

2nd set where I want to grab the name as I get the values {resource_id}:

This is another collection that contains the same value but just thought it would be easier to grab from same collection:
"_id" : "a8727a1d-4661-4565-9c0a-511279024a97",

It looks like these data are in 2 different collections, is this correct?
Would you be able to query CPU data for each "instance_id" ("resource_id")?
Or if this would cause too many queries to the database (looks like you limit to 50...) you could use $in with the list of all "Instance_id"s
http://docs.mongodb.org/manual/reference/operator/query/in/
Either way, you will need to query each collection separately.
