Help on how to use DataStores, retrieving and storing?
I'm trying to make a saving database of someone's department in a group, I have a GUI which successfully changes the Department depending on the entry, but then here's my hard part, how to save it to a DataStore and retrieve it afterwards.
My attempt (Store)
1 | local DataStore = game:GetService("DataStoreService"):GetDataStore("Departments") |
2 | local key = "user_" .. script.Parent.Parent.userId |
3 |
4 | script.Parent.Parent:WaitForChild("leaderstats").Department.Changed:connect(function() |
5 | DataStore:UpdateAsync(key,script.Parent.Parent:WaitForChild("leaderstats").Department.Value) |
6 | --This is where it stops working, "Unable to cast value to function" |
7 | end) |
(Retrieve)
01 | local group = 1234 --GroupID |
02 | local DataStore = game:GetService("DataStoreService"):GetDataStore("Departments") |
03 |
04 | game.Players.PlayerAdded:connect(function(player) |
05 | local leadrsts = Instance.new("IntValue",player) |
06 | leadrsts .Name = "leaderstats" |
07 | local rank = Instance.new("StringValue",leadrsts ) |
08 | rank.Name = "Rank" |
09 | local department = Instance.new("StringValue",leadrsts ) |
10 | department.Name = "Department" |
11 | local key = "user_" .. player.userId |
12 | department.Value = DataStore:GetAsync(key) |
13 | end) |
Any help?
They're both server scripts

The second argument is supposed to be a function, which is maybe why it says error casting it to a function.
01 | --looking at what you did, it looks like you want it to be updated to the Deparment.Value |
02 | --idk if this would work though |
03 | local DataStore = game:GetService("DataStoreService"):GetDataStore("Departments") |
04 | local key = "user_" .. script.Parent.Parent.userId |
05 | local leaderstats = script.Parent.Parent:WaitForChild("leaderstats") |
06 | local Deparment = leaderstats.Department |
07 | Deparment.Changed:connect(function() |
08 | DataStore:UpdateAsync(key, function(old_value) |
09 | local new_value = Deparment.Value |
10 | print(string.format("The old value is %s\n The new value is %s", tostring(old_value), tostring(new_value))) -- I tostringed them because I do not know if this if it is an IntValue or an ObjectValue etc. |
11 | return new_value |
12 | end) |
13 | end) |

Unless is a deeper reason for this happening + the reason I gave TheLowOne 85 — 8y
