I want to update request fields only in an array using java.This is my existing document in mongo db:
{
"_id": "6691e5068dwe335w42cb0a699650f",
"Opportunity_Owner": "Self",
"Account_Name": "IC",
"Lead_Source": "Callbox",
"Opportunity_Name": "name1 ",
"Stage": "Proposal",
"Stage_Status": "A",
"1555570551211": [],
"1555556165153": [],
"1555556059584": [{

"Notes": "Hi Bobby "
},
{
"id": "1557389978181",
"Notes": "Spoken to Bobby."
},
{
"id": "1557389990159",
"Notes": "plan to call on 29/Apr"
}
],
"createdBy": "2c18b8dbb7d74a41a66f53a90117480a",

Request payload:
{

"Stage_Status" : "I",
"1555556059584" : [
{
"id" : "1557389940585",
"Notes" : "updated note 123"
}
]
}
I am trying to update "Stage_Status" and "1555556059584.Notes" at a time using $set.I am able to update "Stage_Status" but "1555556059584" array is going to reset with what i have updated with last one.
expected output:
{
"_id" : "6691e5068dwe335w42cb0a699650f",
"Opportunity_Owner" : "Self",
"Account_Name" : "IC",

"createdDate" : "1562911250917"
}
can any one please help me to figure it out in java.
I guess you wanted to update Stage_Status and 1555556059584.Notes at Once .
here is a demo about it
> db.student.find()
{ "_id" : ObjectId("5d2c09ea8ed60ae70d3dd76b"), "name" : "bigbang", "courses" : [ { "name" : "en", "classRoom" : "9001" }, { "name" : "math", "classRoom" : "1001" } ] }
> db.student.update({name:'bigbang','courses.name':'en'},{ $set: {'courses.$.classRoom':'1009',name :"course"} })
WriteResult({ "nMatched" : 1, "nUpserted" : 0, "nModified" : 1 })
> db.student.find()
{ "_id" : ObjectId("5d2c09ea8ed60ae70d3dd76b"), "name" : "course", "courses" : [ { "name" : "en", "classRoom" : "1009" }, { "name" : "math", "classRoom" : "1001" } ] }
the java demo is like this
collection.updateOne(and(eq("Stage_Status","A"),eq("1555556059584.id","1557389940585")),new Document("$set" ,new Document("Stage_Status","YOUR_NEW_VALUE").append("1555556059584.$.Notes","YOUR_NEW_VALUE")));
you must set the 1555556059584.id to let the diver know which element to be update .

10.0,
8.0,
5.0

},
{
"type" : "exam",
"questions" : [
25.0,
10.0,
23.0,
0.0
]
}
]
}
Example from this link
db.student3.update(
{},
{ $inc: { "grades.$[t].questions.$[score]": 2 } },
{ arrayFilters: [ { "t.type": "quiz" } , { "score": { $gte: 8 } } ], multi: true}
)
ERror I got from robo-3t :
cannot use the part (grades of grades.$[t].questions.$[score]) to traverse the element ({grades: [ { type: "quiz", questions: [ 10.0, 8.0, 5.0 ] }, { type: "quiz", questions: [ 8.0, 9.0, 6.0 ] }, { type: "hw", questions: [ 5.0, 4.0, 3.0 ] }, { type: "exam", questions: [ 25.0, 10.0, 23.0, 0.0 ] } ]})
Please help;

In your update operation
"$set": {
"operations.1.parameters.$.dummy": "foo"
}
refers to the 1st element in operations that is an element with "_id" : "100", and within parameters array, the $ updates the first element in array.
You need to consider using mongodb 3.6 if you want to update nested array elements using $[] to update all matching elements.
One possible way to do this in 3.4 version is fetching the required sub-document and do matches and updates on the application side.
Hi I'm reading data from mongodb into spark application.
My mongodb contains 2 collections.
One is profile_data(actual data with field names)
(Which holds all the input data including some unique fields)
{
"MessageStatus" : 2,
"Origin" : 1,
"_id" : ObjectId("596340fe8b0fa35d2880db1a"),
"accerlation" : 19.4,
"cylinders" : 4,
"displacement" : 119,
"file_id" : ObjectId("59633e48b760e7c8071a6c1c"),
"horsepower" : 82,
"modelyear" : 82,
"modified_date" : ISODate("2017-07-10T08:47:01.641Z"),
"mpg" : 31,
"snet_id" : "new_project",
"unique_id" : "784",
"username" : "chevy s-10",
"weight" : 2720
}
And another collection is : predictive_model_details(Which holds the ML model details like model name, feature fields and prediction field just like metadata)
{
"_id" : ObjectId("56b4351be4b064bb19a90324"),
"algorithm_id" : "55d717a53d9e22022ff2a1e9",
"algorithm_name" : "K- Nearest Neighbours (IBK)",
"client_id" : "562e1d51b760d0e408151b91",
"feature_fields" : [
{
"name" : "Origin",
"type" : "int"
},
{
"name" : "accerlation",
"type" : "Double"
},
{
"name" : "displacement",
"type" : "Int"
},
{
"name" : "horsepower",
"type" : "Int"
},
{
"name" : "modelyear",
"type" : "Int"
}
],
,
"makeActiveStatus" : "0",
"model_name" : "test1",
"parameter_type" : "system_defined",
"parameters" : [
{
"symbol" : "-K",
"value" : "1"
}
],
"predictor" : {
"name" : "mpg"
"type" : "Int"
},
"result_exists" : true,
"snet_id" : "new_project"
}
So I've created 2 datasets in spark for two collections in MongoDB. Now I want to map these 2 Datasets with all feature fields together and prediction field together.
And common field in 2 datasets is snet_id.
Could anyone please help?
Ok so I am making API requests to retrieve certain things like movies, songs, or to ping the server. However all of these responses are contained within the same response JSON object that has varying fields depending on the response. Below are three examples.
ping
{
"response" : {
"status" : "ok",
"version" : "0.9.1"
}
}
getIndexes
{
"response" : {
"status" : "ok",
"version" : "0.9.1",
"indexes" : {
"index" : [ {
"name" : "A",
"movie" : [ {
"id" : "150",
"name" : "A Movie"
}, {
"id" : "2400",
"name" : "Another Movie"
} ]
}, {
"name" : "S",
"movie" : [ {
"id" : "439",
"name" : "Some Movie"
}, {
"id" : "209",
"name" : "Some Movie Part 2"
} ]
} ]
}
}
}
getRandomSongs
{
"response" : {
"status" : "ok"
"version" : "0.9.1"
"randomSongs" : {
"song": [ {
"id" : "72",
"parent" : "58",
"isDir" : false,
"title" : "Letter From Yokosuka",
"album" : "Metaphorical Music",
"artist" : "Nujabes",
"track" : 7,
"year" : 2003,
"genre" : "Hip-Hop",
"coverArt" : "58",
"size" : 20407325,
"contentType" : "audio/flac",
"suffix" : "flac",
"transcodedContentType" : "audio/mpeg",
"transcodedSuffix" : "mp3",
"duration" : 190,
"bitRate" : 858,
"path" : "Nujabes/Metaphorical Music/07 - Letter From Yokosuka.flac",
"isVideo" : false,
"created" : "2015-06-06T01:18:05.000Z",
"albumId" : "2",
"artistId" : "0",
"type" : "music"
}, {
"id" : "3135",
"parent" : "3109",
"isDir" : false,
"title" : "Forty One Mosquitoes Flying In Formation",
"album" : "Tame Impala",
"artist" : "Tame Impala",
"track" : 4,
"year" : 2008,
"genre" : "Rock",
"coverArt" : "3109",
"size" : 10359844,
"contentType" : "audio/mpeg",
"suffix" : "mp3",
"duration" : 258,
"bitRate" : 320,
"path" : "Tame Impala/Tame Impala/04 - Forty One Mosquitoes Flying In Formation.mp3",
"isVideo" : false,
"created" : "2015-06-29T21:50:16.000Z",
"albumId" : "101",
"artistId" : "30",
"type" : "music"
} ]
}
}
}
So basically my question is, how should I structure my model classes to use for parsing these responses? At the moment I have an abstract response object that only contains fields for the status and version. However, by using this approach I will need a response class that extends this abstract class for ever request I make (e.g. AbstractResponse, IndexesResponse, RandomSongsResponse). Also, some models with the same name may have different fields depending on the API request made. I would prefer to avoid making a model class for every possible scenario.
And as an extra note, I am using GSON for JSON serialization/deserialization and Retrofit to communicate with the API.
I'm having an issue in STS creating a custom template. What I want is the ability to do token-based replacement within all files in the project. I've read this is possible with the "token" replacement, but cannot seem to get the wizard.json to let me accept multiple inputs. The "example" you see everywhere is replacing the top-level-package, which I've got to work great.
Anyone have any examples of doing multiple inputs in the wizard.json, or have any idea on what I'm doing wrong?
Here is what I have, which doesn't work:
{
"info" : {
"elements" : {
"element" : [
{
"name" : "mysystem",
"description" : "Please the name of your system (ex. marketing, hr, accounting, etc).",
"type" : "java.lang.String",
"page" : 0,
"required" : true,
"pattern" : "\\w+",
"replaceKind" : "token"
}
],
"element" : [
{
"name" : "myapp",
"description" : "Please the name of your application (ex. thisapplication, thatapplication, etc).",
"type" : "java.lang.String",
"page" : 0,
"required" : true,
"pattern" : "\\w+",
"replaceKind" : "token"
}
]
},
"projectName" : "projectName",
"pages" : {
"page" : [
{
"order" : 0,
"description" : "System Info"
}
]
}
}
}
The "myapp" picks up and does the translation, but the "mysystem" never even gets displayed for input (screen one is just the myapp text).
For those who run into the same problem, I have figured this out. Here is what I ended up with.
{
"info" : {
"elements" : {
"element" : [
{
"name" : "mysystem",
"description" : "Please the name of your system (ex. marketing, hr, accounting, etc).",
"type" : "java.lang.String",
"page" : 0,
"required" : true,
"pattern" : "\\w+",
"replaceKind" : "token"
},
{
"name" : "myapp",
"description" : "Please the name of your application (ex. thisapplication, thatapplication, etc).",
"type" : "java.lang.String",
"page" : 1,
"required" : true,
"pattern" : "\\w+",
"replaceKind" : "token"
}
]
},
"projectName" : "projectName",
"pages" : {
"page" : [
{
"order" : 0,
"description" : "System Info"
}
],
"page" : [
{
"order" : 1,
"description" : "System Info 2"
}
]
}
}
}
