I have documents in which I would like to update the hostUser with one of the members of the document,also have to delete the record from the member document and add the chips of the deleted member in the club chips.
Here is the sample document.
{
"_id" : "1002",
"hostUser" : "1111111111",
"clubChips" : 10000,
"requests" : {},
"profile" : {
"clubname" : "AAAAA",
"image" : "0"
},
"tables" : [
"SJCA3S0Wm"
],
"isDeleted" : false,
"members" : {
"1111111111" : {
"chips" : 0,
"id" : "1111111111"
},
"2222222222" : {
"chips" : 0,
"id" : "2222222222"
}
}
}
This is what I have tried.
db.getCollection('test').updateMany({"hostUser":"1111111111"},
{"$set":{"hostUser":"2222222222"},"$unset":{"members.1111111111":""}})
This is how you would handle unset and set in a single call to updateMany. Can you please clarify what you meant by "check if the values exist in the member field"?
db.getCollection('test').updateMany(
{"hostUser":"1111111111"},
{
'$set': {"hostUser":"2222222222"} ,
'$unset': {"members.1111111111":""}
}
)

I have updateMany function as follows
Article.updateMany({author: userId}, {author: anonym}, function(err, updated) {
if (err) {
res.send(err);
} else {
res.send(updated);
}
});
userId is = 6068b57dbe4eef0b579120c7
anonym is = 6069870676d6320f39e7e5a2
for testing purposes I have a single article in MongoDB as follows
db.articles.find()
{ "_id" : ObjectId("6068b591be4eef0b579120c8"), "favoritesCount" : 1, "comments" : [ ], "tagList" : [ ], "title" : "Martin", "description" : "Testib", "body" : "Asju", "author" : ObjectId("6068b57dbe4eef0b579120c7"), "slug" : "martin-2hzx78", "createdAt" : ISODate("2021-04-03T18:36:01.977Z"), "updatedAt" : ISODate("2021-04-03T18:53:29.809Z"), "__v" : 0 }
You can see that article has "author" : id field in it which currently shows userId as author.
I want to update that field and transfer authorship to anonym user.
When I send this request to postman I get following response
{
"n": 0,
"nModified": 0,
"ok": 1
}
And database remains unchanged. What am I doing wrong here ?
I have almost no experience in SQL or noSQL.
I need to update every document so that my fields "Log*" are under the new field "Log"
I found some help from this StackOverflow, but I am still wondering how to move the data.
Thank you very much
Original document

Final Document
// collection: Services
{
"_id" : ObjectId("5ccb6fa2ae8f8a5d7037a5dd"),
"Name" : "InvoicingService",
"Log" : {
"LogPath" : "Product\\APIService\\",
"LogTypeList" : [
{
"Name" : "ApiComCounter",
"FileName" : "ApiComCounter.log"
},
{
"Name" : "ApiService",
"FileName" : "ApiService.log"
}
]
}
}
This requires MongoDB 4.2 or higher:
db.<collection>.updateMany({}, [
{$set: {"Log.LogPath": "$LogPath", "Log.LogTypeList": "$LogTypeList"}},
{$unset: ["LogPath", "LogTypeList"]}
])
I have two collections one is websites which stores information like:
{
"_id" : ObjectId("5ac5efd6a37efa4c0e28f5aa"),
"main_id" : 3,
"status" : "",
"website" : "http://test.com",
"last_access_time" : "2018-04-16 17:49:03",
"links" : [
{
"link_id" : "test-1",
"link" : "test1.html"
},
{
"link_id" : "test-2",
"link" : "test.html"
}
]
}
And another is website_info in which I want store info like:
{
"_id" : ObjectId("5ad72ddecf45b60dffcbf9f2"),
"main_id" : 3,
"last_access_time" : "2018-04-18 15:37:02",
"test-1" : {
"no_of_links" : 55,
"links_2" : [
{
"link" : "/home",
"link_id" : "secnd-1",
},
{
"link" : "/login",
"link_id" : "secnd-2",
},
{
"link" : "/services",
"link_id" : "secnd-3",
}
]
},
"test-2" : {
"no_of_links" : 55,
"links_2" : [
{
"link" : "/home",
"link_id" : "secnd-1",
},
{
"link" : "/login",
"link_id" : "secnd-2",
},
{
"link" : "/services",
"link_id" : "secnd-3",
}
]
}
}
I am using Python3 and mongoDB.
Here I want to check the field like "link_id" which is "test-1" in the website_info for main_id = 3 exists or not. If it is exists I will update for same, if does not exists I want to insert new record set.
The thing is how to check whether field "test-1" (which is the value from websites collection) in website_info collection exists or not.
Help is appreciated.
Here in my case, link_id will be unique in website_info collection. So no need to check for main_id, only checking for link_id solved my issue, like:
#classmethod
def find_link(self, link_id):
cursor = self.db.collection.find({link_id: {'$exists': True}} )
results = list(cursor)
return results
And check for exists like:
if(len(is_exists)>0):
#do if exists
I want to update a particular property in a nested mongo document
{
"_id" : ObjectId("55af76e60b0e4b318ba822ec"),
"make" : "MERCEDES-BENZ",
"model" : "E-CLASS",
"variant" : "E 250 CDI CLASSIC",
"fuel" : "Diesel",
"cc" : 2143,
"seatingCapacity" : 5,
"variant_+_fuel" : "E 250 CDI CLASSIC (Diesel)",
"make_+_model_+_variant_+_fuel" : "MERCEDES-BENZ E-CLASS E 250 CDI CLASSIC (Diesel)",
"dropdown_display" : "E-CLASS E 250 CDI CLASSIC (Diesel)",
"vehicleSegment" : "HIGH END CARS",
"abc" : {
"variantId" : 1000815,
"makeId" : 1000016,
"modelId" : 1000556,
"fuelId" : 2,
"segmentId" : 1000002,
"price" : 4020000
},
"def" : {
"bodyType" : 1,
"makeId" : 87,
"modelId" : 21584,
"fuel" : "DIESEL",
"vehicleSegmentType" : "E2"
},
"isActive" : false
}
This is my document. If I want to add or update a value for key "nonPreferred" inside "abc", how do I go about it?
I tried it with this query:
db.FourWheelerMaster.update(
{ "abc.modelId": 1000556 },
{
$Set: {
"abc": {
"nonPreferred": ["Mumbai", "Pune"]
}
}
},
{multi:true}
)
but it updates the whole "abc" structure, removed all key:values inside it and kept only newly inserted key values like below
"abc" : {
"nonPreferred" : [
"Mumbai",
"Pune"
]
},
Can anyone tell me how to update only particular property inside it and not all the complete key?
Instead of using the $set operator, you need to push that array using the $push operator together with the $each modifier to append each element of the value separately as follows:
db.FourWheelerMaster.update(
{ "abc.modelId": 1000556 },
{
"$push": {
"abc.nonPreferred": {
"$each": ["Mumbai", "Pune"]
}
}
},
{ "multi": true }
)
I am newbie in MongoDB. I have stored data inside mongoDB in below format
"_id" : ObjectId("51d5725c7be2c20819ac8a22"),
"chrom" : "chr22",
"pos" : 17060409,
"information" : [
{
"name" : "Category",
"value" : "3"
},
{
"name" : "INDEL",
"value" : "INDEL"
},
{
"name" : "DP",
"value" : "31"
},
{
"name" : "FORMAT",
"value" : "GT:PL:GQ"
},
{
"name" : "PV4",
"value" : "1,0.21,0.00096,1"
}
],
"sampleID" : "Job1373964150558382243283"
I want to update the value to 11 which has the name as Category.
I have tried below query:
db.VariantEntries.update({$and:[ { "pos" : 117199533} , { "sampleID" : "Job1373964150558382243283"},{"information.name":"Category"}]},{$set:{'information.value':'11'}})
but Mongo replies
can't append to array using string field name [value]
How one can form a query which will update the particular value?
You can use the $ positional operator to identify the first array element to match the query in the update like this:
db.VariantEntries.update({
"pos": 17060409,
"sampleID": "Job1373964150558382243283",
"information.name":"Category"
},{
$set:{'information.$.value':'11'}
})
In MongoDB you can't adress array values this way. So you should change your schema design to:
"information" : {
'category' : 3,
'INDEL' : INDEL
...
}
Then you can adress the single fields in your query:
db.VariantEntries.update(
{
{"pos" : 117199533} ,
{"sampleID" : "Job1373964150558382243283"},
{"information.category":3}
},
{
$set:{'information.category':'11'}
}
)
