How to delete depricated string fields in options document? - mongodb

Lets say I have a collections 'testCol' with document validation options in its options document.
{
"name" : "testCol",
"type" : "collection",
"options" : {
"validator" : {
"$or" : [
{
"phone" : {
"$type" : "string"
}
},
]
},
"validationLevel" : "moderate",
"validationAction" : "error"
},
...
}
Lets also say I want to delete these options (I am aware that I can set 'validationLevel' to 'off').
I can run db.runCommand('colMod'': testCol', validator: {}) and mongoDB will delete the field 'validator' from the options document. But I can't do the same for 'validationLevel' and 'validationAction'. db.runCommand('colMod'': testCol', validationLevel: ''), does not change anything which leaves me with something like this:
{
"name" : "testCol",
"type" : "collection",
"options" : {
"validationLevel" : "moderate",
"validationAction" : "error"
},
...
}
This is just unclean! Is there a way to get rid of that deprecated string-field options or a way to manipulate/access the options document of a collection directly?

Add field to every document with existing data (move fields data to new field)

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
// collection: Services
{
"_id" : ObjectId("5ccb4f99f4953d4894acbe79"),
"Name" : "WebAPI",
"LogPath" : "Product\\APIService\\",
"LogTypeList" : [
{
"Name" : "ApiComCounter",
"FileName" : "ApiComCounter.log"
},
{
"Name" : "ApiService",
"FileName" : "ApiService.log"
}
]
}
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"]}
])

Update document on mongo

I read several articles and even the mongo doc, but I do not know why this update, updates the item that does not match the condition 'tests.name': 'testY'.
Follow my update and my document, if anyone can help me, please let me know, thank you.
document:
{
"_id" : ObjectId("5b687ac27f71ad55cf3e7c3f"),
"version" : "1.4",
"tests" : [
{
"tag" : "develop",
"name" : "testX",
"team" : "PROC"
},
{
"tag" : "develop",
"name" : "testY",
"team" : "REC"
}
]
}
update:
db.getCollection('testboards').updateOne(
{
'version': "1.4",
'tests.tag': 'develop',
'tests.name':'testY'
},
{
'$set': {'tests.$.team':'NEW'}
}
)
Instead of updating the item 'tests.name': 'testY', the item 'tests.name': 'testX' is updated.
It seems he ignores this condition.

Mongodb update and delete operations in a single query

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":""}
}
)

MongoDB Conditional validation on arrays and embedded documents

I have a number of documents in my database where I am applying document validation. All of these documents may have embedded documents. I can apply simple validation along the lines of SQL non NULL checks (these are essentially enforcing the primary key constraints) but what I would like to do is apply some sort of conditional validation to the optional arrays and embedded documents. By example, lets say I have a document that looks like this:
{
"date": <<insertion date>>,
"name" : <<the portfolio name>>,
"assets" : << amount of money we have to trade with>>
}
Clearly I can put validation on this document to ensure that date name and assets all exist at insertion time. Lets say, however, that I'm managing a stock portfolio and the document can have future updates to show an array of stocks like this:
{
"date" : <<insertion date>>,
"name" : <<the portfolio name>>,
"assets" : << amount of money we have to trade with>>
"portfolio" : [
{ "stockName" : "IBM",
"pricePaid" : 155.39,
"sharesHeld" : 100
},
{ "stockName" : "Microsoft",
"pricePaid" : 57.22,
"sharesHeld" : 250
}
]
}
Is it possible to to apply a conditional validation to this array of sub documents? It's valid for the portfolio to not be there but if it is each document in the array must contain the three fields "stockName", "pricePaid" and "sharesHeld".
MongoShell
db.createCollection("collectionname",
{
validator: {
$or: [
{
"portfolio": {
$exists: false
}
},
{
$and: [
{
"portfolio": {
$exists: true
}
},
{
"portfolio.stockName": {
$type: "string",
$exists: true
}
},
{
"portfolio.pricePaid": {
$type: "double",
$exists: true
}
},
{
"portfolio.sharesHeld": {
$type: "double",
$exists: true
}
}
]
}
]
}
})
With this above validation in place you can insert documents with or without portfolio.
After executing the validator in shell, then you can insert data of following
db.collectionname.insert({
"_id" : ObjectId("58061aac8812662c9ae1b479"),
"date" : ISODate("2016-10-18T12:50:52.372Z"),
"name" : "B",
"assets" : 200
})
db.collectionname.insert({
"_id" : ObjectId("58061ab48812662c9ae1b47a"),
"date" : ISODate("2016-10-18T12:51:00.747Z"),
"name" : "A",
"assets" : 100,
"portfolio" : [
{
"stockName" : "Microsoft",
"pricePaid" : 57.22,
"sharesHeld" : 250
}
]
})
If we try to insert a document like this
db.collectionname.insert({
"date" : new Date(),
"name" : "A",
"assets" : 100,
"portfolio" : [
{ "stockName" : "IBM",
"sharesHeld" : 100
}
]
})
then we will get the below error message
WriteResult({
"nInserted" : 0,
"writeError" : {
"code" : 121,
"errmsg" : "Document failed validation"
}
})
Using Mongoose
Yes it can be done, Based on your scenario you may need to initialize the parent and the child schema.
Shown below would be a sample of child(portfolio) schema in mongoose.
var mongoose = require('mongoose');
var Schema = mongoose.Schema;
var portfolioSchema = new Schema({
"stockName" : { type : String, required : true },
"pricePaid" : { type : Number, required : true },
"sharesHeld" : { type : Number, required : true },
}

How to update particular array element in MongoDB

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'}
}
)
