Retrieving related elements from MongoDB - reactjs

Question

I have the following data in MongoDB. Based alone on an id that I have available how can I retrieve all other entries where the player matches the player for my current id.
For example : find who the player for id 12 is, search all other entries that match that player name and return a list of all of them.
[
{_id: '62ecdf342f1193134043964c', id: '12', player: 'David Beckham', team: 'Manchester United'},
{_id: '62ecdf342f1193134043965c', id: '17', player: 'Cristiano Rolando', team: 'Manchester United'},
{_id: '62ecdf342f1193134043966c', id: '22', player: 'Cristiano Rolando', team: 'Juventus'},
{_id: '62ecdf342f1193134043967c', id: '42', player: 'David Beckham', team: 'Real Madrid'},
]
This is the code that I'm using to retrieve the one single entry that matches a specific id and then I'd also like to get the related entries.
export async function getStaticProps({ params }) {
const { db } = await connectToDatabase();
const jerseyA = await db
.collection("Jerseys")
.find({ id: params.jersey })
.sort()
.toArray();
const jersey = JSON.parse(JSON.stringify(jerseyA))[0];
return { props: { jersey } };
}

Answer 1

Now that you know the name, do another fetch like .find({player: jersey.player})

I'm not sure of the output format you want, but here's one way to return all documents that match the "player" name of the given "id".
db.Jerseys.aggregate([
{
"$match": {
// your id goes here
"id": "17"
}
},
{
"$lookup": {
"from": "Jerseys",
"localField": "player",
"foreignField": "player",
"as": "docs"
}
},
{"$unwind": "$docs"},
{"$replaceWith": "$docs"}
])
Example output:
[
{
"_id": "62ecdf342f1193134043965c",
"id": "17",
"player": "Cristiano Rolando",
"team": "Manchester United"
},
{
"_id": "62ecdf342f1193134043966c",
"id": "22",
"player": "Cristiano Rolando",
"team": "Juventus"
}
]

Just an addition to #rickhg12hs solution, to ignore the first record. You can use the following query to ignore the first record (where the id also matched) and the others.
db.Jerseys.aggregate([
{
"$match": {
"id": "12"
}
},
{
"$lookup": {
"from": "Jerseys",
"localField": "player",
"foreignField": "player",
"as": "docs"
}
},
{
"$unwind": "$docs"
},
{
"$replaceWith": "$docs"
},
{
"$match": {
"id": {
"$not": {
"$eq": "12"
}
}
}
}
])
A possible javascript translation of it, should be,
export async function getStaticProps({ params }) {
const { db } = await connectToDatabase();
const { jersey: id } = params;
const jerseyA = await db
.collection("Jerseys")
.aggregate([
{
"$match": {
id
}
},
{
"$lookup": {
"from": "Jerseys",
"localField": "player",
"foreignField": "player",
"as": "docs"
}
},
{
"$unwind": "$docs"
},
{
"$replaceWith": "$docs"
},
{
"$match": {
"id": {
"$not": {
"$eq": id
}
}
}
}
]).toArray();
const jersey = JSON.parse(JSON.stringify(jerseyA))[0];
return { props: { jersey } };
}
