In the scenario, how to give the EL$ for the field 'location' and 'ID'.
I tried giving as below but getting error as Attribute not defined for 'ID' and 'Location'
.body(
StringBody(
"""{"name": "${name}", "Url": "${Url}", “Product”: [ { "ID": "${ID}", "location": "${location}" } ] }"""
)
).asJson
JSON:
[
{
"name":"xyz",
"url":"test1.com",
"Product":[
{
"ID":111111,
"location":"NewYork"
}
]
},
{
"name":"abc",
"url":"test2.com",
"Product":[
{
"ID":22222,
"location":"Texas"
}
]
}
]
The ID and location fields are inside a Product object, so the correct Gatling EL String would be respectively #{Product.ID} and #{Product.location}.

I am having the below document structure:
[
{
"network_type": "ex",
"rack": [
{
"xxxx": {
"asn": 111111,
"nodes": {
"business": [
"sk550abcc1eb01.abc.com",
"sk550abcc1eb10.abc.com",
"sk550abcc1eb19.abc.com",
"sk550abcc1eb28.abc.com"
]
},
"region": "ex-01",
"zone": "01a"
}
}
]
}
]
I need to rename/update the key array element "xxxx" to "details".
I tried the below command, but it doesn't seem to work.
db.collection.update({},
{
$rename: {
"rack.xxxx": "details"
}
})

Please help me.
You can't direct $rename the field name which is within the array.
Instead,
Iterate with document(s) in the rank array, create the details field with the value of xxxx and next append this field to each document.
Remove the path with $rank.xxxx to remove the xxxx field from the document(s) in the rank array.
db.collection.update({},
[
{
$set: {
rack: {
$map: {
input: "$rack",
in: {
$mergeObjects: [
{
"details": "$$this.xxxx"
},
"$$this"
]
}
}
}
}
},
{
$unset: "rack.xxxx"
}
])

How can i filter 'array' of object ids inside of mongo document, so that it doesn't include "60ba4ca6f170dsfa234", and will update document. Thank you!
{
"_id" : ObjectId("60bfdae011abd61c3eec"),
"array" : [
ObjectId("60ba4ca6f170dsfa234"),
ObjectId("60bd240df30ead9293d")
}
You can make use of the $project pipeline stage with the $filter option.
db.collection.aggregate([
{
"$project": {
"array": {
"$filter": {
"input": "$array",
"cond": {
"$ne": [
"$$this",
{ // <-- Ignore this block and pass value directly you are passing `ObjectId` directly drom driver and conversion from string is not required
"$toObjectId": "60407d54a8204c86a62bf231" // <-- ObjectId you want to be removed from the array
}
],
},
}
},
},
},
{
"$merge": {
"into": "collection", // <-- Change to source collection name where the changes has to be updated
"on": "_id",
"whenMatched": "merge",
},
},
])
Mongo Playground Sample Execution
I have the following query and it works with $in but not with $nin.
I'm trying to remove the link list items by name (itemA and itemB) from all records that are NOT part of a document that has a user name which contains '#not_these' or '#nor_these'.
db.users.update({userName:{$nin: [ RegExp('#not_these.com'), RegExp('#nor_these.com') ]}},{$pull:{'myLinkList': {name: {$in: ['itemA', 'itemB']} } } } )
If I make it $in and and declare the RegExp() explicitly it does remove the array items as expected.
db.users.update({userName:{$in: [ RegExp('#yes_these.com'), RegExp('#and_these.com') ]}},{$pull:{'myLinkList': {name: {$in: ['itemA', 'itemB']} } } } )
This one does remove itemA and itemB array list items for those explicitly declared users.
Why can't the items '#yes_these' and '#and_these' be removed using the first example? It seems to do nothing when executed.
Sample document:
{
"_id": ObjectId('5e34741aa18d8a0c24078b61'),
"myLinkList": [
{
"name": "item",
"created": ISODate('2020-01-31T18:38:18.682Z'),
"managedBy": [
"imm"
]
},
{
"name": "itemA",
"created": ISODate('2020-01-31T18:38:18.682Z'),
"managedBy": [
"imm"
]
},
{
"name": "itemB",
"created": ISODate('2020-01-31T18:38:18.682Z'),
"managedBy": [
"imm"
]
}
],
"userName": "#yes_these.com"
}
After update (hopefully):
{
"_id": ObjectId('5e34741aa18d8a0c24078b61'),
"myLinkList": [
{
"name": "item",
"created": ISODate('2020-01-31T18:38:18.682Z'),
"managedBy": [
"imm"
]
}
],
"userName": "#yes_these.com"
}
I verified this did work:
db.users.updateMany({userName:{$nin: [ /#not_these\.com/), /#nor_these\.com/) ]}},{$pull:{'myLinkList': {name: {$in: ['itemA', 'itemB']} } } } )
I have mongoDB content as below:
[

Here I have an array named 'Category' where it contains objects with different category id.
I need to
select a particular category id - '57c3df061eb1e59d3959cc40'
From the above selected Category, we get 'Value' array
From Value array need to find if the second value is equal to 'ZZZZZ' ie. value[1] == 'ZZZZZ'
And now, update the matched value arrays with a new value at the end
Eg:
[
"232323",
"ZZZZZ",
"1999"
]
should be updated to
[
"232323",
"ZZZZZ",
"1999",
"update1"
]
and
[
"8888",
"ZZZZZ",
"1999"
]
should be updated to
[
"8888",
"ZZZZZ",
"1999",
"update1"
]
I have tried as below:
resume.update({
"Category.CategoryId": new ObjectId('57c3df191eb1e59d3959cc43'),
"Category.Value.$.1": 'ZZZZZ'
},
{"$set": {"Category.Value.$.3": "update1"}
}, function(err, resData){
res.send(resData);
});
But, nothing gets updated. Its there any way to get this work. Please help to update the inner array.
Thanks in advance.
Your goal is not possible at the moment since you need to update two positional elements.
There is a JIRA trackable for the sort of behaviour you want here: https://jira.mongodb.org/browse/SERVER-831
It's a problem since you need to match two elements positions:
the Category element with the matched CategoryId
the Value element in the Value array of arrays
If one of these wouldn't be an array it would have been possible.
Anyway, Your update try above was wrong. IF this feature was possible (and it is not!!!) it would have been something like this:
db.resume.update(
{
Category: {
$elemMatch: {
CategoryId: ObjectId('57c3df061eb1e59d3959cc40'),
Value: {
$elemMatch: {
'1': 'ZZZZZ'
}
}
}
}
},
{
$push: {
'Category.$.Value.$': 'update1'
}
}
)
The positional $ operator should be used during the update and not the find like you did, and it will update the first element that matched the query.
Doing the above will return the error:
Too many positional (i.e. '$') elements found in path 'Category.$.Value.$'
Because of the missing feature I explained at the top.
So, currently (version 3.2) you will not be able to do this unless you change your schema.
I'm using ElasticSearch in my system and I have a question.
When I use GET in this uri:
/dev/category/_search
I receive this:
{
...
"title": "Sound",
"slug": "sound",
...
}
It's correct. But I have many fields in this query and I want to optimize this one.
I GET this uri:
/category/_search?show_in_menu=true&fields=title,slug
When I add the param fields, all fields are returning as array. In this example, return this:
"fields": {
"slug": [
"Sound"
],
"title": [
"sound"
]
}
There is a way to return only the field intead of an array?
Thanks!
You can apply source filtering
Allows to control how the _source field is returned with every hit.
Example from documentation:
{
"_source": {
"include": [ "obj1.*", "obj2.*" ],
"exclude": [ "*.description" ],
}
"query" : {
"term" : { "user" : "kimchy" }
}
}
Hope it helps.
