I want to push one value in attachments array using mongodb. I want to update query using following criteria.
_id:ObjectId("5b56bd2f3e18580edc85af73") "cardID": ObjectId("5b56c895d0a04836f71aa776") "commentId":"2"
I want to push value in attachments, any help would be appreciated
This is a collection object:
{
"_id" : ObjectId("5b56bd2f3e18580edc85af73"),
"orgId" : "90",
"createdBy" : "test",
"name" : "testname",
"Cards" : [
{
"cardID" : ObjectId("5b56c895d0a04836f71aa776"),
"cardName" : "test Name",
"cardCreated" : "",
"reviewer" : "",
"priority" : "",
"cardPosition" : "",
"membersAssigned" : [
"ggg",
"fff"
],
"labels" : [
"l1",
"l2"
],
"description" : "",
"attachements" : [],
"comments" : [
{
"commentId" : "2",
"commentedBy" : "test",
"date" : "",
"comment" : "Hello world",
"attachements" : [
"1",
"data"
],
"emojis" : [
":smile:",
":thumbsup:"
],
"updatedBy" : "arkadata",
"updatedOn" : "",
"subComments" : {
"commentedBy" : "jaril",
"date" : "",
"comment" : "Hello world inside dark"
}
},
{
"commentId" : "3",
"commentedBy" : "test",
"date" : "",
"comment" : "Hello world",
"attachements" : [
"1",
"raj"
],
"emojis" : [
":smile:",
":thumbsup:"
],
"updatedBy" : "arkadata",
"updatedOn" : "",
"subComments" : {
"commentedBy" : "jaril",
"date" : "",
"comment" : "Hello world inside dark"
}
},
{
"commentId" : 6.0
}
],
"dueDate" : "",
"createdDate" : "",
"lastUpdated" : "",
"checkList" : [],
"position" : "5",
"status" : "active"
},
"timestamp" : ISODate("2018-07-24T05:46:23.890Z")
}
You can try with mongodb 3.6 arrayFilters
db.collection.update(
{ "_id": ObjectId(5b56bd2f3e18580edc85af73) },
{ "$push": { "Cards.$[card].comments.$[comment].attachments": "2" } },
{ "arrayFilters": { "card.cardID": ObjectId("5b56c895d0a04836f71aa776"), "comment.commentId": 2 } }
)
Make sure you cast your ids to ObjectId
db.collection.update(
{ "_id": ObjectId(5b56bd2f3e18580edc85af73) },
{ "$push": { "Cards.$[card].comments.$[comment].attachments": "2" } },
{ "arrayFilters": [
{ "card.cardID": ObjectId("5b56c895d0a04836f71aa776")},
{"comment.commentId": 2 }
]
}
)
