Hi Benjamin,

If you add the following to your UploadCompleteMessage you will be able to keep a custom runtime collection with all of the details of the files uploaded by users. This would include any data that you set to the "uploadData" of the GetUploadUrlRequest.

//in your UploadCompleteMessage Cloud Code

var dataToGrab = Spark.getData().uploadData;

var uploadedFiles = Spark.runtimeCollection("uploadedFiles");

var success = uploadedFiles.insert({"uploadedData":dataToGrab})


//example request

{
 "@class": ".GetUploadUrlRequest",
 "uploadData": 
  {"test":"value"}
}

//example of document in custom collection after successful upload 

{
 "_id": {
  "$oid": "58053fc538c31604dd9a69c7"
 },
 "uploadedData": {
  "fileName": "eb7a5ecf50ce40d59132877706c46efe-2016-09-07_17h13_43.jpg",
  "uploadId": "eb7a5ecf50ce40d59132877706c46efe",
  "test": "value",
  "fileSize": 689094,
  "origFileName": "2016-09-07_17h13_43.jpg",
  "playerId": "5800f32a8b146964b4b4038f"
 }
}

You will then be able to query this as you would a normal collection. If you have any further questions just let me know.

Thanks,

Liam
