Using REST API, I am getting the JSON response from the below Ajax hit for loading datatable.
I am getting error: Uncaught TypeError: Cannot read property 'length' of undefined.
$('#example').dataTable({
"bSort" : false,
"bDestroy" : true,
"sPaginationType" : "full_numbers",
"bProcessing" : false,
"bFilter" : true,
"bServerSide" : true,
"bAutoWidth" : false,
"sAjaxSource" : 'exampledatagrid.json?token=' + sessionId,
"aoColumns" : [{
"mData" : "0",
"mData" : "1",
"mData" : "2",
"mData" : "3"
}],
"fnServerParams" : function(aoData) {
alert(aoData);
aoData.push({
"name" : "colNameMode",
"value" : "userStatusList"
}, {
"name" : "colName_0",
"value" : "userIDList"
}, {
"name" : "colName_1",
"value" : "userNameList"
}, {
"name" : "colName_2",
"value" : "userRemarksList"
});
},
"fnRowCallback" : function(nRow, aData, iDisplayIndex) {
alert(aData);
},
"fnDrawCallback" : function(oSettings) {
if ( oSettings.bSorted || oSettings.bFiltered ) {
for ( var i=0, iLen=oSettings.aiDisplay.length ; i<iLen ; i++ ) {
$('td:eq(0)', oSettings.aoData[ oSettings.aiDisplay[i] ].nTr ).html( i+1 );
}
}
}
});
JSON response is :
{"userRemarksList":["TECHNOLOGY","GUEST","HOUSE","SECURITY"],"userIDList":[23,45,23,54],"userNameList":["Michael","Danny","Rahil","Ramesh"],"userStatusList":[0,0,1,1]}
I want to know whether I have to change my JSON format or if I can retrieve from the above JSON response itself?
I got the answer by making a change in my back-end by quering the results using hibernate "org.hibernate.query". from this i was able to obtain the list of records (one-by-one) and load it into the grid respectively.

I am using Springboot and MongoTemplate for the find Query. If I want to retrieve a subdomain based on "domains.subdomain.name" field, can I get only the subdomain json from a mongo query, or do I get the entire document and then iterate and filter the subdomain in my java code.
Use $unwind and then $replaceWith
db.collection.aggregate([
{
$match: {
"domains.subdomains.name": "name1"
}
},
{
$unwind: "$domains"
},
{
$unwind: "$domains.subdomains"
},
{
$match: {
"domains.subdomains.name": "name1"
}
},
{
$replaceWith: "$domains.subdomains"
}
])

Mongodb 4.2.15
I'm tring to use mongo Updates with Aggregation Pipeline
My request is very big but here it's core structure
db.runCommand({
"update": "collectionName",
"updates": [
{
"q": { ... },
"u": [
{
"$project": { ... },
"$set": { ... },
"$set": { ... },
"$project": { ... }
}
],
"multi": false,
"upsert": true
}
]
});
After the first execute I receive a result with newly created object's _id
{
"n" : 1,
"nModified" : 0,
"upserted" : [
{
"index" : 0,
"_id" : ObjectId("619997f11501d6eb40c6f64a")
}
],
"opTime" : {
"ts" : Timestamp(1637455857, 61),
"t" : NumberLong(5)
},
"electionId" : ObjectId("7fffffff0000000000000005"),
"ok" : 1.0,
"$clusterTime" : {
"clusterTime" : Timestamp(1637455857, 61),
"signature" : {
"hash" : { "$binary" : "hA0tf5DXMqTNmnVXdMVnpnAKCU0=", "$type" : "00" },
"keyId" : NumberLong(7018546168816730116)
}
},
"operationTime" : Timestamp(1637455857, 61)
}
After the second execution of the same request there is no modified object's _id
{
"n" : 1,
"nModified" : 1,
"opTime" : {
"ts" : Timestamp(1637456057, 19),
"t" : NumberLong(5)
},
"electionId" : ObjectId("7fffffff0000000000000005"),
"ok" : 1.0,
"$clusterTime" : {
"clusterTime" : Timestamp(1637456057, 19),
"signature" : {
"hash" : { "$binary" : "U2yCP6nXUrjBN9ZiLanyl0rgxww=", "$type" : "00" },
"keyId" : NumberLong(7018546168816730116)
}
},
"operationTime" : Timestamp(1637456057, 19)
}
The thing is that my filter conditions do not contain _id of the object but I need to return it with response. I see no useful request configurations. Any suggestions is it possible to get _id at response on update case?
I have got a below document in Mongodb collection , need to get the value of result of false with Java syntax .Any help can be appreciated .
{
"_id" : ObjectId("5f0890e870e631865877e"),
"user" : "testuser",
"Email" : "testuser#sample.com",

},

"Wild" : {
"System" : "Wild",
"result" : true
}
}
{
"CRaft" : {
"System" : "Craft",
"result" : false
}
}
],
I can't go like Email Systems.Bob.result ,Email Systems.Wild.result,Email Systems.Craft.result .Can anyone suggest how to get the result value from all systems with Java synatax.
I do have an unique index with a partialFilterExpression on a collection but duplicate data is sometimes inserted.
Index creation
getCollection().createIndex(new BasicDBObject(userId, 1)
, new BasicDBObject("name", "uidx-something-user")
.append("partialFilterExpression", new BasicDBObject(Properties.someting, new BasicDBObject("$eq", true)))
.append("unique", true));
The index from the getIndicies command
{
"v" : 1,
"unique" : true,
"key" : {
"userId" : 1
},
"name" : "uidx-something-user",
"ns" : "somewhere.something",
"partialFilterExpression" : {
"something" : {
"$eq" : true
}
}
}
The duplicated Docuemnts
{
"_id" : "08a8506c-bcbc-4ed6-9972-67fd7c37b4bc",
"userId" : "1068",
"express" : false,
"something" : true,
"items" : [ ],
"recipient" : {
"_id" : "efbd8618-c480-4194-964e-f5a821edf695"
}
}
{
"_id" : "b6695c6a-f29d-4531-96ac-795f14c72547",
"userId" : "1068",
"express" : false,
"something" : true,
"items" : [ ],
"recipient" : {
"_id" : "4f93fe38-edb2-4cb7-a1b3-c2c51ac8ded1"
}
MongoDb version: 3.2.7, seems also to happen with 3.2.12
A Sidenote: When dumping the collection and restoring it, a duplicate key error is thrown
Why is it sometimes possible to insert duplicate data and how to avoid that?
UPDATE
I created an MongoDb issue https://jira.mongodb.org/browse/SERVER-28153
Was fixed in 3.2.13, 3.4.4, 3.5.6

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.
