Find cards that increased prices
|
|
|
|
db.cards.find({$expr: {$gt: [{$arrayElemAt: ["$serra_prices", -2]}, {$arrayElemAt: ["$serra_prices", -1]}]}}, {name:1})
|
|
|
|
Update card Price
|
|
|
|
db.cards.update(
|
|
{'_id':'8fa2ecf9-b53c-4f1d-9028-ca3820d043cb'},
|
|
{$set:{'serra_updated':ISODate("2021-11-02T09:28:56.504Z")},
|
|
$push: {"serra_prices": { date: ISODate("2021-11-02T09:28:56.504Z"), value: 0.1 }}});
|
|
|
|
Set value
|
|
|
|
db.cards.aggregate([{ $group: { _id: { set: "$set" }, value: { $sum: { $multiply: ["$prices.eur", "$serra_count"] } }, count: { $sum: 1 } } }])
|
|
|
|
Color distribution
|
|
|
|
db.cards.aggregate([{ $group: { _id: { color: "$colors" }, count: { $sum: 1 } } }])
|
|
|
|
Calculate value of all sets
|
|
|
|
db.sets.aggregate({$match: {serra_prices: {$exists: true}}}, {$project: {name: 1, "totalValue": {$arrayElemAt: ["$serra_prices", -1]} }}, {$group: {_id: null, total: {$sum: "$totalValue.value" }}})
|
|
|
|
Calculate what cards gained most value in percent
|
|
|
|
db.cards.aggregate({$project: {set: 1, collectornumber:1, name: 1, "old": {$arrayElemAt: ["$serra_prices.value", -2]}, "current": {$arrayElemAt: ["$serra_prices.value", -1]} }}, {$match: {old: {$gt: 2}}} ,{$project: {name: 1,set:1,collectornumber:1,current:1, "rate": {$subtract: [{$divide: ["$current", {$divide: ["$old", 100]}]}, 100]} }}, {$sort: { rate: -1}})
