DataStore Saving as Array Instead of Dictionary

Help and Feedback Scripting Support
#1

What do you want to achieve?
I want to make it so it saves the player’s data in the dictionary. ([playername] = score)

What is the issue?
The data is printing ([1] = “WoofWoofWatermelonYT”).

What solutions have you tried so far?
I tried doing:

		table.insert(Players_Complete, player.Name)
		Players_Complete[player.Name] = score

but it errors as expecting a number.

Original script:

		table.insert(Players_Complete, 1, player.Name)
		Players_Complete[player.Name] = score

If you know how to fix, please let me know. Thanks!

Edit: Entire code is below. :slight_smile:

local Players_Complete = {}

game.ReplicatedStorage.Server.OnServerEvent:Connect(function(player, result, score, timetaken)
	local url = "not showing :)"
	local http = game:GetService("HttpService")
	local data
	if result == "Passed." then
		Players_Complete[player.UserId] = score
		print(Players_Complete)
		local success, errormessage = pcall(function()
			local DataStoreService = game:GetService("DataStoreService")
			local LevelStore = DataStoreService:GetDataStore("CurrentQuizzes")
			LevelStore:SetAsync("QuizData", Players_Complete)
		end)
		if success then
		else
			warn(errormessage)
		end
		for key, value in pairs(Players_Complete) do
			print(key .. " is " .. value)
		end
		data = {
			["embeds"] = {
				{
					["title"] = "Quiz Results",
					["description"] = "**Result**\n" .. result .. "\n\n**Score**\n" .. score .. "\n\n**Time Taken**\n" .. timetaken,

	http:PostAsync(url, finaldata)
end)

table.insert inserts the Player name as a dictionary Players_Complete = {"Player"} and the 2nd line is an array Players_Complete = {["Player"] = 1] so you can just leave the 2nd line

table.insert, when only one parameter follows the table parameter, actually saves as a value and not a key. What you’re doing is:

Players_Complete = {
    "PlayerName",
    ["PlayerName"] = score
}

Just set the key-value pair as it is without table.insert:

Players_Complete[player.Name] = score
print(Players_Complete[player.Name])

Error: ServerScriptService.Server:8: attempt to index nil with ‘WoofWoofWatermelonYT’ (It is supposed to add the player to the dictionary after it fires to the server).

#5

To my knowledge you can’t really use table.insert() on a dictionary.

Try Dictionary[player.Name] = {}.

From there you can go:
Dictionary[player.Name].Score = Score

#6

I said to keep the 2nd line of your original script

#7

I kept the second line only. Don’t know the issue.

#8

I tried that just now, didn’t work.

#9

Try user Player.UserId instead of Player.Name.

#10

ServerScriptService.Server:8: attempt to index nil with number

#11

The dictionary is empty, and I want it to insert a value in it once an event is fired.

#12

You should NOT be using table.insert here. Dictionaries never need to have the values added to them via table.insert. Doing:

Players_Complete[player.Name] = score

would work way better. Also, please don’t use the player’s name when saving data. Player’s are able to change their name at any point, so this isn’t a good way to store data. The better way would be to save the player’s UserId, which is a unique identifier.

Players_Complete[player.UserId] = score

This should work.

#13

When the dictionary is empty, it should work?

#14

Also, I’m still getting:

ServerScriptService.Server:8: attempt to index nil with number

#15

To my knowledge, the only time a dictionary could be empty after setting it, would be if the value being set was nil. Print out the score value and see if its actually valid, or just nil.

#16

It prints out a string value (the score).

#17

If the error

is still happening, can you please print out Players_Complete before setting the value, and see if thats nil?

#18

It’s nil. (If the datastore doesn’t detect any previous data, it doesn’t add anything to it. However, if there is a value in it, then it adds it into the dictionary). P.S. I’ll print Players_Complete right when you join the server and see what happens.

#19

Oh, I think I know why. I’ll just make it if the data is nil, it won’t do anything to the dictionary since it might be deleting the table.
