Bind mongodb json to kendo grid - kendo-ui

Question

I am very new to kendo UI and getting similar challenges as below(except I dont mind having a fixed data structure for grid):
How to pass MongoDb Json value to KendoUI grid using webservice method
$("#grid").kendoGrid({
dataSource: {
transport: {
read: {
url: "http://localhost:8080/urlPath",
dataType: "json",
}
},
schema: {
data: "score"
}
columns:[{
field: "physics"
},
{
field: "chemistry",
}],
});
Json looks like:
[{"score"[{"physics:99", "chemistry" :95}]},{"score"[{"physics:99", "chemistry" :95}]}]
I am struggling from last few days and have tried approaches like:
Convert dbcursor object into json
http://www.codeconfuse.com/2014/03/mongodb-convert-data-getting-from.html
Here's the related code from above URL:
while(cursor.hasNext()) {
BasicDBObject obj = (BasicDBObject) cursor.next();
jsonobj = new JSONObject();
BasicDBList name = (BasicDBList) obj.get("Name");
jsonobj.put("Incident Date", obj.getString("Incident Date"));
jsonarray.put(jsonobj);
}
return jsonarray;
JSON json =new JSON();
String serialize = json.serialize(cursor);
But the kendo Grid seems to be rejecting it. Please assist.

Answer 1

My issue got resolved by formatting the json returned in an appropriate format as below:
From:
[{"score"[{"physics:99", "chemistry" :95}]},{"score"[{"physics:99", "chemistry" :95}]**}]**
To:
[{"physics:99", "chemistry" :95}]},{"score"[{"physics:99", "chemistry" :95}]
So, basically I extracted the score object, put into my own hashmap and then returned the json object. See below for sample code:
*
DB db = mongoClient.getDB( "test" );
DBCollection coll = db.getCollection("mycol");
BasicDBObject fields = new BasicDBObject("score",true).append("_id",false);
BasicDBObject query = new BasicDBObject();
DBCursor cursor = coll.find(query,fields)
while (cursor.hasNext()) {
DBObject obj = cursor.next();
BasicDBList scoreList = (BasicDBList) obj.get("score");
for (int i = 0; i < scoreList.size(); i++) {
BasicDBObject scoreObj = (BasicDBObject) scoreList.get(i);
String physics = scoreObj.getString("physics");
String chemistry = scoreObj.getString("chemistry");
//ofcourse we need another innerloop here to iterate through
//all the rows of the returned list.
innerMap.add("physics",physics);
innerMap.add("chemistry",chemistry);
}
return new Gson().gson(map.values);
}
