Setmetatable ignore updating table when using loop although it supposed to

I want to update my table. But I wouldn’t update even if I update the Table then setmetatable it or after it still only result with it not updating.
It work by setting the value normally but when I try to use for loop on it to counts how many instance are in the child it just won’t work.

local SharedFolder = ReplicatedStorage:WaitForChild("Shared")
local ServerFolder = ServerScriptService:WaitForChild("Server")
local ClientFolder = game.StarterPlayer.StarterPlayerScripts:WaitForChild("Client")

local Classes,Packages,Engine,Modules,Services,Assets,Remotes = {},{},{},{},{},{},{}
local MetaData = {["Modules"]=0,["Running_Modules"]=0,["Loaded_Modules"]={},["Error_Modules"]={}}

local Settings = {["Debug"]=true}
local Framework={
	["Shared"]={
		["Folder"] = SharedFolder,
		["Classes"]={
			["Data"] = {},
			["Setting"]={
				["Meta"]=true,
				["Table"]=Classes,
				["Folder"]={}

for _,Folders in pairs(Framework) do

Modules()
--All I think that it must be something when using #Services["Setting"]["Folder"]:GetChildren()

Is your MetaData table supposed to be unique for each service or is it supposed to be shared?

#3

The services variable are shared, the for loop is just to set it up and setmetatable for it include function and index to the actual services in the framework table.

#4

Oh, okay I think I see what you’re saying, for loops don’t run what’s in a metatable even if you set the index to another table.

There are two ways that I can think about that allow you to sort through the index with a for loop:

------------------ [ 1 ] ------------------
-- // From your provided info
local Table = setmetatable(Services["Setting"]["Table"],{
		__index = Services, 

		__call = function(Table,Object)
			print(Table["Data"]) --Modules haven't change
		end
})

local Services = getmetatable(Table).__index -- // Probably not recommended; 

for index, value in pairs(Services) do 
    -- . . .
end

------------------ [ 2 ] ------------------

local Methods   = {}
Methods.__index = Methods,
Methods.__serviceIndex = Services,
Methods.__call  = function(Table,Object)
		print(Table["Data"]) --Modules haven't change
end
-- // returning meta index
function Methods:GetService()
    return self.__serviceIndex
end

local Table = setmetatable(Services["Setting"]["Table"], Methods)

for index, value in pairs(Table:GetService()) do
    -- . . .
end

Don’t mean to keep editing this just small errors but does relatively the same thing.

I have been trying your methods but I can’t seem to how to fix my problems. I don’t understand what wrong with my code or why it act like that maybe I will try to find a workaround

I just know my problem and has fixed it. It turn out that this line of code

Services["Data"] = MetaData

has caused the problem instead of

#Services["Setting"]["Folder"]:GetChildren()

It seem like the problem was because I am setting the Table Variable into Another Table Variable which caused it to like clone each other. It was an easy fix by cloning the table.
