I want to sum of values inside array of objects which have another array of objects. In my case; how can I count 'url' values in all documents inside 'urls' array under 'iocs' array;
Mongo playground: open
Here is document example;
[
{
"_id": {
"$oid": "63b4993d0625ebe8b6f5b06e"
},
"iocs": [
{
"urls": [
{
"url": "7.1.5.2",
}
],
},
{
"urls": [
{
"url": "https://l-ink.me/GeheimeBegierde",
},
{
"url": "GeheimeBegierde.ch",
}
],
},
{
"urls": [
{
"url": "https://l-ink.me/GeheimeBegierde",
}
],
}
],
type: "2"
},
{
"_id": {
"$oid": "63b4993d0624ebe8b6f5b06e"
},
"iocs": [
{
"urls": [
{
"url": "7.1.5.2",
}
],
},
{
"urls": [
{
"url": "https://l-ink.me/GeheimeBegierde",
},
{
"url": "GeheimeBegierde.ch",
}
],
},
{
"urls": [
{
"url": "https://l-ink.me/GeheimeBegierde",
}
],
}
],
type: "3"
},
{
"_id": {
"$oid": "63b4993d0615ebe8b6f5b06e"
},
"iocs": [
{
"urls": [
{
"url": "www.google.com",
}
],
},
{
"urls": [
{
"url": "abc.xyz",
},
{
"url": "GeheimeBegierde.ch",
}
],
},
{
"urls": [
{
"url": "https://123.12",
}
],
}
],
type: "1"
}
]
expected output be like;
url: "7.1.5.2",
count:2,
types:[2,3]
url: "https://l-ink.me/GeheimeBegierde",
count:4,
types:[2,3],
url: "abc.xyz",
count:1,
types:[1],
I tried unwind iocs then project urls but can't figure out how to get this output. I think i must use group but how ? Newbie in mongodb.
Any help would be appreciated. Thanks all.
NOTE: All the answers are working. Thank you all for the contributing.
You could do something like this !
db.collection.aggregate([
{
"$unwind": "$iocs"
},
{
"$unwind": "$iocs.urls"
},
{
"$group": {
"_id": "$iocs.urls.url",
"count": {
"$sum": 1
},
"types": {
"$addToSet": "$type"
}
}
},
{
"$project": {
url: "$_id",
_id: 0,
types: 1,
count: 1
}
},
])
