How to insert a value into a dictionary?

Help and Feedback Scripting Support
#1

so i have been making a modulescript allowing u to create a private server using reserveserver however i want to assign it to another code thats shorter i did that but it says attempt to index nil with “code” so how do i insert the values like this

local table = {
[“qwewqrq”] = “private server key”
}
etc
and here is the code

local module = {}
local TS = game:GetService("TeleportService")
local DTS = game:GetService("DataStoreService")
local CodesDatastore = DTS:GetDataStore("CodesDatastore")
local alphabet = {"a","b","c","d","e","f","g","h","i","j","k","l","m","n","o","p","q","r","s","t","u","v","w","x","y","z"}
local codetable = CodesDatastore:GetAsync("Codes")

function module:CreatePrivateServer(placeid)
	local id
	local succes, err = pcall(function()
		id = TS:ReserveServer(placeid or game.PlaceId)
	end)
	if succes then
		local code = ''
		for i = 5,1,-1 do
			local letter = alphabet[math.random(1,#alphabet)]
			code = code..letter
		end
		codetable[code] = tostring(id)
		local codeid = codetable[code]
		print(codetable)
		CodesDatastore:SetAsync("Codes",codetable)
		
	else
		print(err)
	end
	
end


function module:GetCodes()
	return codetable
end

return module

Perhaps it’s better to do this? Since data can be nil

local codetable = CodesDatastore:GetAsync("Codes") or {}
#3

i actually had that before i will put it back and see if the error goes away

#4

still however this time it is at line 19 saying attempt to index nil with “ydbef” the codes are randomly generated tho

#5

try to print the table codetable before running.

	if succes then
		print(codetable)
		local code = ''
		...
#6

it will still be empty as i assign the code to the id at line 21 but ok

#7

it now has no errors and says table = 0x02131 or some long code however it should be
table = [“qweasr”] = 0x02131

#8

can you send a screenshot/table?

#9

it means everything works for you, because in the game the table looks like this when printed. You can also print the table with a loop (if you want).

for i, v in pairs(codetable) do
	print(i, v)
end
#12

but why cant i see the key and the value? i only see the value

#13

if i print it in the loop it doesnt print anything

#14

Are you sure? try this code to see what’s wrong.

codetable[code] = tostring(id)
print(code)
local codeid = codetable[code]
print(codeid)
for i, v in pairs(codetable) do
	print(i, v)
end
#15

it works now all of a sudden ig it was just an error in the datastore

#16

i marked it as solution thanks man!
