MongoDB EmbedsMany Query - mongodb

So I'm using loopback to create a RESTful node.js API. I'm using mLab for my database. I'm trying to query data that is embedded inside of my Account model.
An Account model has a property called favorites which has an array of Songs.
Here is an example:
{
"_id": {
"$oid": "58512c1b7c05c491b2cff1f6"
},
"firstName": "Matt",
"lastName": "Thomas",
"username": "mattietea",
"password": "$2a$10$dcquPHK48H5Q7FcaTyzgf.vnrUOgKpBENS9fSa0hjoaASs0uyOWba",

"_favorites": [

}
I have an endpoint set up which returns all the favorites
api/Accounts/{id}/favorites
But I can't seem to query them. When I query all the songs from api/Songs it works but not when I query favorites.
The query I'm using is:
{'order': 'created DESC'}
I've tried multiple other queries, and none work.
Thank you!

Query nested object in mongodb without key

I have multiple documents saved which look like the one shown below, how would I query against a nested object without the ID to receive the right document?
Here is what I current, but this doesnt work, as I dont have the ID at the start.
db.collection.find({
"details.hardware.id": 5,
})
This is what ive tested and know works but I dont know the ID -
db.collection.find({
"100201.details.hardware.id": 5,
})
Document example -
[
{
"_id": {
"$oid": "6338b69062433c04642d26ca"
},
"100201": {
"broken": true,
"details": {
"build": {
"id": 1018458,
},
"hardware": {
"id": 5,
"model": {
"id": 131,

any help would be appreciated

Loopback 3: Multiple HasOne relation on one model

So, I opened an issue here, coz in my opinion it should work as I think... but might be wrong so looking for another way
So, pretty much I have two models, Wedding and Person. The Wedding one has these relations set:
"people": {
"type": "hasMany",
"model": "person",
"foreignKey": "",
"options": {
"nestRemoting": true
}
},
"partner1": {
"type": "hasOne",
"model": "person",
"foreignKey": ""
},
"partner2": {
"type": "hasOne",
"model": "person",
"foreignKey": ""
}
And one of my wedding documents looks like this (I am using mongoDB if you cannot tell):
{
"_id": "5de78c76f89d1a8ad4091ca5",
"date": "2019-12-04T10:37:42.000Z",
"userId": "5de78c76f89d1a8ad4091ca4",
"created": "2019-12-04T10:37:42.720Z",
"partner1Id": "5de78c77f89d1a8ad4091ca6",
"partner2Id": "5de78c77f89d1a8ad4091ca7"
}
So, when I set include filter and do:
{ "include": ["partner1", "partner2"]}
in my loopback API explorer on
http://localhost:3000/api/weddings/5de78c76f89d1a8ad4091ca5
I get:
{
"date": "2019-12-04T10:37:42.000Z",
"id": "5de78c76f89d1a8ad4091ca5",

"created": "2019-12-04T10:37:42.720Z",
"partner1Id": "5de78c77f89d1a8ad4091ca6",
"partner2Id": "5de78c77f89d1a8ad4091ca7",
"partner1": {
"id": "5de78c77f89d1a8ad4091ca7",
"fullName": "Jessica Alba",
"spouse": "spouse2",
"contacts": [],
"verified": false,
"created": "2019-12-04T10:37:43.292Z",
"updated": "2019-12-04T10:37:43.292Z",
"userId": "5de78c76f89d1a8ad4091ca4",
"weddingId": "5de78c76f89d1a8ad4091ca5"
},
"partner2": {
"id": "5de78c77f89d1a8ad4091ca7",
"fullName": "Jessica Alba",
"spouse": "spouse2",
"contacts": [],
"verified": false,
"created": "2019-12-04T10:37:43.292Z",
"updated": "2019-12-04T10:37:43.292Z",
"userId": "5de78c76f89d1a8ad4091ca4",
"weddingId": "5de78c76f89d1a8ad4091ca5"
}
}
But, I am expecting this:
{
"date": "2019-12-04T10:37:42.000Z",
"id": "5de78c76f89d1a8ad4091ca5",
"userId": "5de78c76f89d1a8ad4091ca4",
"created": "2019-12-04T10:37:42.720Z",
"partner1Id": "5de78c77f89d1a8ad4091ca6",
"partner2Id": "5de78c77f89d1a8ad4091ca7",
"partner1": {
"id": "5de78c77f89d1a8ad4091ca6",
"fullName": "Michael Knight",
"spouse": "spouse1",
"contacts": [],
"verified": false,
"created": "2019-12-04T10:37:43.292Z",
"updated": "2019-12-04T10:37:43.292Z",
"userId": "5de78c76f89d1a8ad4091ca4",
"weddingId": "5de78c76f89d1a8ad4091ca5"
},
"partner2": {
"id": "5de78c77f89d1a8ad4091ca7",
"fullName": "Jessica Alba",
"spouse": "spouse2",
"contacts": [],
"verified": false,
"created": "2019-12-04T10:37:43.292Z",
"updated": "2019-12-04T10:37:43.292Z",
"userId": "5de78c76f89d1a8ad4091ca4",
"weddingId": "5de78c76f89d1a8ad4091ca5"
}
}
Any ideas as of why? why do I get the same two records for partner1 and partner2?
Instead of using "hasOne", use "belongsTo".

Nested grouping of array

There are 3 master collection of category , subcategory and criteria each, i will be building framework with any possible combination of category , subcategory and criteria which will be stored as below-
framework document is added below having list of criteriaconfig as embedded object which further have single object of category , subcategory and criteria. you can refer criteriaconfig as link table that u call in mysql.
[

i need a view containing framework that will contain all list of category and inside category there will be list of added subcategory and inside subcategory will have list of criteria for single framework.
expected result -

]
}]
}
]
Note - Category document doesn't have any reference to subcategory and same way subcategory doesn't have any reference to criteria object currently as they are master data and are generic , framework is created with their combination dynamically.
If you want to try to do all the work in the aggregation, you could group first by subcategory, then by category like:
db.collection.aggregate([
{$unwind:"$criteriaConfigs"},
{$project:{
_id:0,
category:"$criteriaConfigs.category",
subCategory:"$criteriaConfigs.subCategory",
criteria:"$criteriaConfigs.criteria"
}},
{$group:{
_id:{"category":"$category","subCategory":"$subCategory"},
criteria:{$addToSet:"$criteria"}
}},
{$group:{
_id:{"category":"$_id.category"},
subCategories:{$addToSet:{subCategory:"$_id.subCategory",
criteria:"$criteria"}}
}},
{$project:{
_id:0,category:"$_id.category",
subCategories:"$subCategories"
}}
])
Depending on how you plan to us the return data, it may be more efficient to return each unique combination:
db.collection.aggregate([
{$unwind:"$criteriaConfigs"},
{$group:{
_id:{
category:"$criteriaConfigs.category.name",
subCategory:"$criteriaConfigs.subCategory.name",
criteria:"$criteriaConfigs.criteria.name"
}
}},
{$project:{
_id:0,
category:"$_id.category",
subCategory:"$_id.subCategory",
criteria:"$_id.criteria"
}}
])
I'm not sure from your question what shape you are expecting the return data to have, so you may need to adjust for that.

Mongodb query inside array with single ObjectID

}
Now, I entered this mongo query:
db.data.find( {"_id" : ObjectId("58ee59f7f35120aaba26cff0")},{ items: { $elemMatch: { "date": {$gte:"2017-04-08T04:30:44.240163+00:00"} } } } )
But it returns just a single item which is the first one. If I try $lte, it also returns single item but I want all the items which fall under the specification of date. How to achieve that?
Your date field is a string, it has no concept of what's greater than that string. You'll need to convert it to a ISODate or another date format for you to use the $gte or $lte operation.

Domino 9.x calendar service create meeting

I have been following this guide to work on Domino 9.0.1
Domino Calendar services
I am using JSON and the POST command works but creates an appointment, what I want to do is create a meeting. I have tried setting other fields like event['x-lotus-appttype'].data or event.AppointmentType = 3 but I still get an appointment.
JSON I am sending
{
"events": [
{
"summary":"Meeting 1",
"location":"Location 1",
"start": {
"date":"2013-12-01",
"time":"13:00:00",
"utc":true
},
"end": {
"date":"2013-12-01",
"time":"14:00:00",
"utc":true
}
}
]
}
What is the correct JSON format to create a meeting ?
Take a look at the following documentation: Event with attendees represented in JSON format
EXAMPLE 4. Event with attendees and time zone array:
{
"x-lotus-charset": {
"data": "UTF-8"
},
