Here is the structure of my main schema:
_id: id,
random: random,
cards: [objectId, objectId, ...] //ref to cards
An example of a card in the schema:
_id: id,
random: random,
random: random,
clicks: 15.
I am looking to sort the top schema based on the total number of clicks within the cards.
Instructions for Query1
_id)*For descending order, use sort -1 instead of 1
Test query here
mainColl.aggregate(
[{"$lookup":
{"from": "cardCollection",
"localField": "cards",
"foreignField": "_id",
"as": "clickSum"}},
{"$set": {"clickSum": {"$sum": "$clickSum.clicks"}}},
{"$sort": {"clickSum": 1}}])
Steps for Query2
Test query here
mainColl.aggregate(
[{"$lookup":
{"from": "cardsCollection",
"localField": "cards",
"foreignField": "_id",
"pipeline":
[{"$group": {"_id": null, "clicksSum": {"$sum": "$clicks"}}}],
"as": "clicksSum"}},
{"$set": {"clicksSum": {"$arrayElemAt": ["$clicksSum.clicksSum", 0]}}},
{"$sort": {"clickSum": 1}}])
After some experimentation, I ultimately settled on the following solution:
model.aggregate([
{$lookup: {from: "cards", localField: "cards", foreignField: "_id", as: "cards"}},
{$set: {clickSum: {$sum: "$cards.clicks"}}},
{$sort: {clickSum: -1}}
])
