I need to update a particular element of the nested array in mongoDB
My mongoDB data looks like below. I need to match the value accessid and name to update the status. The input content has
{"accessid" : 1627047023995, "name" : Name 09, "status" : 100 }
The input content may belong to any level
{
"_id" : ObjectId("60fac46ffcbf5287248460a9"),
"levelone" : [
{
"level" : [
{
"name" : "Name 01",
"status" : 5
},
{
"name" : "Name 02",
"status" : 0
},
{
"name" : "Name 03",
"status" : 0
}
],
"accessid" : "1627047023995"
},
{
"level" : [
{
"name" : "Name 09",
"status" : 5
},
{
"name" : "Name 15",
"status" : 3
}
],
"accessid" : "1627047023995"
}
],
"createdAt" : ISODate("2021-07-23T13:30:23.995Z")
}
I have tried to update the status, but it is updating only the first index value - name: Name 01 status. Please guide to resolve the issue.
collections.updateOne({
'levelone.level.accessid': accessid,
'levelone.level.name': name
}, { '$set': { 'levelone.$.level.status': status } }).exec();
you can use arrayFilters positional update,
$elemMatch to filter the main documenta variable for accessid and b for nameawait collections.updateOne({
levelone: {
$elemMatch: {
accessid: accessid,
"level.name": name
}
}
},
{
$set: {
"levelone.$[a].level.$[b].status": status
}
},
{
arrayFilters: [
{ "a.accessid": accessid },
{ "b.name": name }
]
})
