Hi, i've noticed that when i run a request on a NOSQL item, it overwrites the entire NOSQL item with the request data.
Is it possible to just update a specific item value, instead of an entire NOSQL item?
Example
NOSQL item
playerStash{
value1 "3"
value2 "five hundred-6"
value3 "moredata"
}

Hi Laura,
Sorry about that. The original error was coming from my attempt to concatenate the field name "playerStash."+data.slot. To resolve this, you'd need to construct the object you're using to update the document prior to performing the query, so it would look something like this:
If you have any further questions please let us know.

I currently use something like this to update data.
With your above example, should i just use that 1 liner, or maybe can you post an example based on my existing code? Thank you.
var playerDataList = Spark.runtimeCollection("PlayerData"); // this will get the collection of player data
var ID = Spark.getPlayer().getPlayerId(); // first we get the id of the current player
var playerBaseData = Spark.getData().STASH2;
var currentPlayer = {
"playerID": ID,
"playerStash2": playerBaseData
}; // we construct a new player from the data we are about to input into the player data
playerDataList.update({
"playerID": ID
}, //Looks for a doc with the id of the current player
{
"$set": currentPlayer
}, // Uses the $set mongo modifier to set old player data to the current player data
true, // Create the document if it does not exist (upsert)
false // This query will only affect a single object (multi)
);

Hi Laura,
Using the $set operator means there should no longer be any need to first retrieve the existing player document and modify it before updating your collection. Something like this should do the trick:
Spark.runtimeCollection("PlayerData").update(
{"playerID":Spark.getPlayer().getPlayerId()},
{"$set":{"playerStash2":Spark.getData().STASH2}} //you can update multiple fields using {$set:{"playerStash1":myValue1, "playerStash2":myValue2,...etc}}
)
Give this a go and let us know how it works for you.

Hi Vinnie, this works to store a specific value, but the problem is the Create Log Event Attributes, and created GS Data within Unreal, overwrites all the other values inside that NOSQL item (in above example playerStash2).
Attached is an image of my Unreal node setup (switching between different player stashes), and the NOSQL item i try to update. When i run above code only one value remains inside the NOSQL table. I can circumvent this when i save all values at once, but i want to preserve bandwith, hence my question.

Hi Laura,
I see. In this situation, it will depend on what data you're sending to your event (your playerBaseData value). For example, if you're sending a single inventory item and you know which slot you wish to store it in you could use:
If, on the other hand, you were sending an object with multiple items to store, and which slots to store them against, you would need to include the path to said item slots, e.g.
Alternatively, if you don't know in which slot you wish to store your items, you would need to first retrieve the existing document, iterate through it to find an empty slot, update that slot's value with that passed in, the update the database document with the new data.
I hope this helps. If you have any further questions please let us know.

Vinnie

Thanks for the examples.
Is there a way to use a single script to save values in the root, with changing item slots?

Hi Laura,
Sorry, just to clarify, when you metioned changing item slots - you want the value being sent to be stored in the first available item slot, or one specified in the data?

Hi Laura,
Let's say the data in 'Spark.getData().STASH2' resolves to this:
{"item":"Sword-Knight-0","slot":"StashSlot5"}
You could apply this to the player's document using:
var data = Spark.getData().STASH2;
Spark.runtimeCollection("PlayerData").update(
{"playerId":Spark.getPlayer().getPlayerId()},
{"$set":{"playerStash."+data.slot:data.item}}
);
If you only specifiy the slot number in the data being sent:
I get now this error missing } after property list (event/Save_Player2_Item.js#10)
Thank you

Hi Laura,
You can use Mongo's $set operator to update individual fields within a document. For example:
Spark.runtimeCollection("myCollection").update({"playerId":Spark.getPlayer().getPlayerId},{$set:{"value1":10}})
If you have any further questions please let us know.

I try to use the last code snippet in my cloud code query, but i get this error
missing : after property id
Customer Support
Hi Laura
It looks like a small typo in the code can you change the + to : in this line
{"$set":{"playerStash."+data.slot:data.item}} to
{"$set":{"playerStash.":data.slot:data.item}}

Could you post the entire Cloud Code again, when i use this example
var data = Spark.getData().ITEM2;
Spark.runtimeCollection("PlayerData").update(

Thank you Vinnie, this seems to work now, great.
Btw, do you have an example for loading data via an array for Unreal?
We tried this but doesn't work. Ps. let me know and i create a new topic for that question.
