Module datastore help

Help and Feedback Scripting Support
#1

i did a module datastore script that worked perfectly, i tried making it soo i could add new values without breaking the datastore completely, because my game will always be updated with new content everyday, and with my old datastore scripts i had to wipe data every single time i updated, and now it ins’t saving, soo what i need is help to fix the scripts and make soo i can add new values whenever i want without having to data wipe, 100% of the roblox games dont need to data wipe when adding new content to the datastore, but when i search how to do that, i either cant find anything or people tell me to use datastore 2 (which is super messy), also someone said using datastore 2 doesn’t changes anything soo yeah

problems: broken save script, need to wipe data everytime i add new values

module script:

local dsinfo = {
	folder_name = "DATA";
	ds_name = "WDYF_TEST0333";
	key = "WDYF-";
	
	data = {
		coins = {"IntValue", 0};
	};
};

return dsinfo

server script (inside the module, however i dont think thats the problem)

local PS = game:GetService("Players")
local RUN = game:GetService("RunService")
local DSS = game:GetService("DataStoreService")
local DSM = require(script.Parent)
local DS = DSS:GetDataStore(DSM.ds_name)

function save(p)
	local key = DSM.key .. p.userId
	local tosave = {}
	
	local folder = p:FindFirstChild(DSM.folder_name)
	if not folder then return end
	
	for _, stat in pairs(folder:GetChildren()) do
		tosave[stat.Name] = stat.Value
	end
	
	local s, e = pcall(function()
		DS:SetAsync(key, tosave)
	end)
	
	if not s then
		warn(p.Name .. " Data Error: " .. e)
	end
end


PS.PlayerRemoving:Connect(save)
PS.PlayerAdded:Connect(function(p)
	local key = DSM.key .. p.userId
	local currentsave = DS:GetAsync(key)
	
	local folder = Instance.new("Folder",p)
	folder.Name = DSM.folder_name
	
	for name, stat in pairs(DSM.data) do
		local newval = Instance.new(stat[1])
		newval.Name = name
		newval.Value = stat[2]
		newval.Parent = folder
	end
	
	if currentsave then -- LOAD
		for l, stat in pairs(folder:GetChildren()) do
			if currentsave[stat.Name] then
				stat.Value = currentsave[stat.Name]
			else
				local missing = DSM.data[stat.Name]
				stat.Value = missing
				currentsave[stat.Name] = missing
			end
		end
		
		save(p)
		
		for l,s in pairs(currentsave) do
			print(l, s)
		end
	else
		save(p)
	end
end)

-- # studio bugfix # -- (not the problem btw)
game:BindToClose(function()
	wait(5)
end)

You should iterate through the module’s dsinfo table to check if everything is there.

local currentsave = DS:GetAsync(key) or {}
for i,v in pairs(module.data) do
    if currentSave[i] == nil then -- if the current index isn't inside of currentSave (we have to explicitly check if it isn't nil as not false is true, not nil is also true) then create it.
        currentSave[i] = v
    end
end
-- then iterate through the data and create the new objects as needed
for i,v in pairs(currentSave) do
    local currentObject = Instance.new(i[1])
    currentObject.Parent = folder
    currentObject.Name = i
    currentObject.Value = v[2]
end

where should i put that line of code

It was just some quick pseudocode that has to be adjusted to your circumstance but probably inside of your load func.
