And operator mongoosastic (filter) - mongodb

How can I add filter to my query to get for example just users where role admin ?
Here is my query:
userModel.search({
"multi_match": {
"fields": ["firstName", 'lastName', 'specialities', 'profession', 'country', 'state', 'city'],
"query": req.query.q,
"fuzziness": "AUTO"
}
},
{
from: (pageNum - 1) * perPage,
size: perPage
},
function (err, results) {
...
I need to do something like this just with mognoosastic:
ElasticSearch - multi-match with filter - returns no result

Try Below Query Format
"query": {
"bool": {
"must": {
"multi_match": {
"query": "values",
"fields": [
"filed_one","field_two"
]
}
},
"filter": {
"range": {
"field_name": {
"gte": 1467311400,
"lte": 1468866599
}
}
}
}
}
Let me know if this format help or not

for anyone looking for solution to this,
You can use the MQL where clause in your pipeline stage definition.
{
$match: {
email:"email#domain.com"
}
}

Updating a nested array object in Mongo

I have a StudentClass collection that looks like this:
[
{
"_id": ObjectId("60923c997b4d3205009a981a"),
"attended": [
{
"in": "2021-05-05T06:35:05.226+00:00",
"out": "2021-05-05T06:45:05.226+00:00"
},
{
"in": "2021-05-05T06:47:05.226+00:00",
"out": "2021-05-05T06:55:05.226+00:00"
},
{
"in": "2021-05-05T06:56:05.226+00:00"
},
{
"in": "2021-03-03T07:10:00.628Z"
}
],
"studentId": ObjectId("608a42e8224c549ad9a9ab51"),
"active": true
},
{
"_id": ObjectId("6098f6f974af29682772fbe6"),
"attended": [
{
"in": "2021-05-05T06:35:05.226+00:00",
"out": "2021-05-05T06:55:05.226+00:00"
},
{
"in": "2021-05-05T06:59:05.226+00:00",
"out": "2021-05-05T07:20:05.226+00:00"
}
],
"studentId": ObjectId("608a42e8224c549ad9a9ab51"),
"active": true
},
{
"_id": ObjectId("6098f6f974af29682772fbe7"),
"attended": [],
"studentId": ObjectId("608a42e8224c549ad9a9ab51"),
"active": true
}]
For a give _id, I need to update the attended array as per the following conditions:
Need to find the last array element with a missing out key. That array element of the attended should get updated with the out key just like other array elements.
This is what I've tried:
const markStudentExitFromClass = (studentClassId, exitTime) => {
return new Promise((resolve, reject) => {
StudentClasses.updateOne(
{ _id: new mongoose.Types.ObjectId(studentClassId), "attended.out" : {$exists: false}},
{ $set: { "attended.$.out": new Date(exitTime) } },
function (err, updatedData) {
if (err) {
reject(err);
} else {
resolve(updatedData);
}
}
)
})
}
This is not updating any array element of attended array for the give _id. Just like $ positional operator finds the first array element, is there anything for the last array element?
What am I doing wrong?
Updated:
So, I got the update part working by changing the match clause of updateOne to:
const markStudentExitFromClass = (studentClassId, exitTime) => {
return new Promise((resolve, reject) => {
StudentClasses.updateOne(
{ _id: new mongoose.Types.ObjectId(studentClassId), "attended" :{"$elemMatch":{"out":{$exists: false}}} },
{ $set: { "attended.$.out": new Date(exitTime) } },
function (err, updatedData) {
if (err) {
reject(err);
} else {
resolve(updatedData);
}
}
)
})
}
But, I still cant figure out how to get the last matching element of the attended array instead of the first. Any pointers?

group by properties and sum of values between nested json and array of objects

I have users array with their name,
var users = [{'name':'zulekha'}, {'name':'deepika'}];
I am fetching worklogged by each user from jira APIs. So I am getting object like this.
var worklogResult = {
"issues": [
{
"fields": {
"worklog": {
"worklogs": [
{
"author": {
"name": "zulekha",
},
"timeSpentSeconds": 180
},
{
"author": {
"name": "deepika",
},
"timeSpentSeconds": 210
}
]
}
}
},
{
"fields": {
"worklog": {
"worklogs": [
{
"author": {
"name": "deepika",
},
"timeSpentSeconds": 140
}
]
}
}
},
{
"fields": {
"worklog": {
"worklogs": [
{
"author": {
"name": "zulekha",
},
"timeSpentSeconds": 600,
}
]
}
}
},
{
"fields": {
"worklog": {
"worklogs": []
}
}
}
]
}
Now I want to match worklogResult with users in such a way that I can get following output.
output = [{'name':'zulekha','timeSpentSeconds':780}, {'name':'deepika', 'timeSpentSeconds':350}]
Can anyone suggest me how to achieve this?
use _.flatMap to flat nested objects
_.chain(worklogResult.issues)
.flatMap('fields.worklog.worklogs')
.thru(function(spents) {
return _.map(users, function(user) {
return _.merge(user, {
timeSpentSeconds: _.chain(spents)
.filter(['author.name', user.name])
.map('timeSpentSeconds')
.sum()
.value()
})
})
})
.value()

Finding multiple docs using same id not working, using meteor + react and mongoDB

How do I get the email address of the students in the same class_id, take it as there are more then 2 students in different class in the DB as well?
I have this but it return empty array []
Meteor.users.find({"course_learn_list.$.class_id": {$in: [classId]}},
{field: {"emails.address": 1}}
).fetch()
Collections
{
"_id": "LMZiLKs2MRhZiiwoS",
"course_learn_list": [
{
"course_id": "M8EiKfxAAzy25WmFH",
"class_id": "jePhNgEuXLM3ZCt98"
},
{
"course_id": "5hbwrfbfxAAzy2nrg",
"class_id": "dfbfnEuXLM3fngndn"
}
],
"emails": [
{
"address": "student1#gmail.com",
"verified": false
}
]
},
{
"_id": "JgfdLKs2MRhZJgfNgk",
"course_learn_list": [
{
"course_id": "M8EiKfxAAzy25WmFH",
"class_id": "jePhNgEuXLM3ZCt98"
},
{
"course_id": "5hbwrfbfxAAzy2nrg",
"class_id": "dfbfnEuXLM3fngndn"
}
],
"emails": [
{
"address": "student2#gmail.com",
"verified": false
}
]
}
I think you want:
Meteor.users.find({ "course_learn_list.class_id": classId },
{ "course_learn_list.$": 1, "emails.address": 1 }).fetch()
This should find the first instance in each course_learn_list array where the classId is your classId.
In this case you probably don't need to use a projection to get the right answer. Here's an example of extracting the verified email addresses using only the . operator in the selector:
const ids = ['jePhNgEuXLM3ZCt98', 'some-other-id'];
const emails =
Meteor.users.find({ 'course_learn_list.class_id': { $in: ids } })
.fetch()
.map(user => _.findWhere(user.emails, { verified: true }).address);
This works for me!
Meteor.publish("getMyClassStudents", function(classId) {
console.log("Publish getMyClassStudents")
var self = this
if (self.userId) {
var data = Meteor.users.find({
"course_learn_list.class_id": classId
}, {
"fields": {
"emails.address": 1
}
})
return data
}
else {
return self.ready()
}
})

auto-increment using loopback.js and MongoDB

i want to increase mongodb document number automatically using loopback.
I made function in mongo
function getNextSequence(name) {
var ret = db.counters.findAndModify(
{
query: { _id: name },
update: { $inc: { seq: 1 } },
new: true
}
);
return ret.seq;
}
db.tweet.insert(
{
"_id" : getNextSequence("userid"),
"content": "test",
"date": "1",
"ownerUsername": "1",
"ownerId": "1"
}
)
It is working in mongo shell.
However when I insert using loopback.js browser (http://localhost:3000/explorer/), It is not working.
400 error(SytaxError) code is showing.
I can not use mongo function in loopback rest API ?
I think problem is quotes in this line getNextSequence("userid"),
Create a collection counters with properties value and collection
{
"name": "counters",
"base": "PersistedModel",
"idInjection": true,
"options": {
"validateUpsert": true
},
"properties": {
"type": "number",
"collection": "string"
},
"validations": [],
"relations": {},
"acls": [
{
"accessType": "*",
"principalType": "ROLE",
"principalId": "$everyone",
"permission": "ALLOW"
}
],
"methods": []
}
Now supposing your auto-increment collection name tweets.
Insert this value to counters.
{
"value" : 0,
"collection" : "tweet"
}
Now common/models/tweet.js
tweet.observe('before save', function (ctx, next) {
var app = ctx.Model.app;
//Apply this hooks for save operation only..
if(ctx.isNewInstance){
//suppose my datasource name is mongodb
var mongoDb = app.dataSources.mongodb;
var mongoConnector = app.dataSources.mongodb.connector;
mongoConnector.collection("counters").findAndModify({collection: 'tweet'}, [['_id','asc']], {$inc: { value: 1 }}, {new: true}, function(err, sequence) {
if(err) {
throw err;
} else {
// Do what I need to do with new incremented value sequence.value
//Save the tweet id with autoincrement..
ctx.instance.id = sequence.value.value;
next();
} //else
});
} //ctx.isNewInstance
else{
next();
}
}); //Observe before save..
I would love to add 1 more point to Robins Answer,you can add upsert:true so that it automatically creates the document if it doesn't exist
tweet.observe('before save', function (ctx, next) {
var app = ctx.Model.app;
//Apply this hooks for save operation only..
if(ctx.isNewInstance){
//suppose my datasource name is mongodb
var mongoDb = app.dataSources.mongodb;
var mongoConnector = app.dataSources.mongodb.connector;
mongoConnector.collection("counters").findAndModify({collection: 'tweet'}, [['_id','asc']], {$inc: { value: 1 }}, {new: true,upsert:true}, function(err, sequence) {
if(err) {
throw err;
} else {
// Do what I need to do with new incremented value sequence.value
//Save the tweet id with autoincrement..
ctx.instance.id = sequence.value.value;
next();
} //else
});
} //ctx.isNewInstance
else{
next();
}
}); //Observe before save..
You can do something like in this example for loopback 4
let last_record = await this.testRepository.findOne({order: ['id DESC']});
if(last_record) invoice.id = last_record.id+1;
This will generate your model with the property:
#property({
type: 'number',
id: true,
default: 1,
generated: false
})
id: number;
Hopefully, this helps, please write me if there is any other code. Thanks
If you want to use MongoDB operators directly in loopback methods you need to enable the option "allowExtendedOperators", you can do so on a per model basis or at the data source level (will apply to all models using the data source).
